  • H24 personalized weather forecast services and medical hotline
  • Preparation course, live expedition coverage
  • Guaranteed departure from the first participant

Lhotse (8516 m), the fourth highest peak on the planet, is often overlooked. It represents a major objective for any mountaineer wishing to climb several 8000-meter peaks. The ascent route is the same as that of Everest up to Camp 3 (7100 m). Beyond this point, the route divides at the characteristic band of yellow rock. Camp 4 at 7950 meters, halfway between the South Col and the foot of the "Reiss" couloir, is the real starting point for the ascent. In fact, the 1956 Swiss expedition made the first ascent of Lhotse before successfully setting off on the slopes of Everest. And more often than not, mountaineers plan to climb Lhotse in the wake of Everest, thus saving substantial costs. But you still need to be in good physical condition.

We also offer an ascent of Everest via its southern slopes and Tibet.

Overview

We set off to climb Lhotse (8516 m), the fourth highest peak on the planet. It represents a major objective for any mountaineer wishing to climb more than one 8000-meter peak. The ascent route is the same as that of Everest up to Camp 3 (7100 m). Beyond this point, the route divides at the characteristic band of yellow rock. Camp 4 at 7950 meters, halfway between the South Col and the foot of the "Reiss" couloir, is the real starting point for the ascent. In fact, the 1956 Swiss expedition made the first ascent of Lhotse before successfully tackling the slopes of Everest.

To ensure a trip in the best possible conditions, we concentrate our resources, strength and expertise on small teams.   

The approach trek to base camp includes essential acclimatization time, with a rest day in Namche Bazar and Lobuche. A few days at base camp complete the acclimatization process, or better still, you can climb Lobuche Peak (6119 m). By making this ascent, you'll be perfectly acclimatized and will be able to reduce the number of rotations to Camp 2 and, consequently, the time spent in the Khumbu Icefall.

Here is the animated itinerary for the ascent of Everest from both sides, South Nepalese and North Tibetan.


MOUNTAINEERS' WORDS

These words from the mountaineers who climbed Everest apply perfectly to our ascent of Lhotse.

"What is it that makes this summit so fascinating to all mountaineers?... It is the highest mountain in the world... The many expeditions, the men who have conquered it, have not succeeded in making it smaller... The altitude remains." – Reinhold Messner

"We didn't have to wait for the ultimate vision. Above the fog, Everest was still before us...: motionless as Keats's star in its solitary splendor, and so high in the night! Eternal watchman of the shadows, the Mount seemed to inebriate the world with its radiance." - George Leigh Mallory

"Suddenly, it occurred to me that the ridge in front of us, instead of continuing to rise, was falling sharply; much lower down, I could see the North Col and the Rongbuck Glacier; in the foreground, a narrow snow ridge climbed towards a snowy summit; a few more ice axe strokes in the hardened snow... and we were at the summit. It was 11:30 a.m." - Edmund Hillary May 29, 1953

COLLECTIVE ADVENTURE

While it remains an exceptional adventure, the ascent of an 8000er is no longer an undertaking reserved for a very high-level alpine elite. Advances in logistics, mountain equipment, weather forecasting, gear and the physical fitness of mountaineers mean that the world's highest peaks are now accessible to technically autonomous, well-trained and highly motivated mountaineers.

Our expedition will be a collective adventure, a confluence of motivations and energies, a meeting of the capacities of an organization and motivated climbers. Two parallel challenges will have to be met:

  • for the participants: to be physically, technically and mentally at the top of their game at all times;
  • for the organizer: to provide irreproachable logistics enabling access to the high altitude camps under optimum conditions. Beyond that, it is up to the participants to play their part, taking part independently in the assaults on the summit ridge led by the guide and sherpas.

The main objective of this expedition is to experience an adventure that requires total commitment, both physical and moral, acting with lucidity and humility in a hostile natural environment that forgives no imprudence or temerity leading to death. It is this testimony that must be wisely remembered.

Good observance of all safety rules is essential, as is good physical and psychological preparation, a warm and supportive environment, total serenity, a little tactics and then, if the weather is kind and luck is on your side, you will be able to count down the magic minutes at the summit when effort ceases and nothingness fills the space and instills itself within you.

It is agreed by all parties that giving up is never a failure, but that accepting it can also be a victory over oneself. Any preparation, even the most meticulous, any will, even the most tenacious, can be defeated by the adversity of natural environments whose force is exponentially stronger than the finest human intelligence. Let the gods bless us and allow us to tread the summit.

THE MOTTO IS: DARE TO CLIMB, KNOW HOW TO DESCEND


VERY HIGH ALTITUDE

Advice from Hubert Giot, mountain guide. He has taken part in several expeditions to 8000 meters and climbed Everest without oxygen.

It is not easy to establish rules, because mountaineers are not equal when it comes to altitude, either physiologically or mentally. Everyone seems to have their own plateau where they get stuck. Extremely demanding, this stage is always painful, but not unmanageable. Once you are past this stage, everything's fine... or not so bad. It's generally at this point that you get a better idea of your ability to adapt. This can happen as early as 6000 meters, or even earlier, during the approach trek.

High altitude also has its own rules, and transgressing them becomes inherently dangerous. There is a fundamental difference between climbing to 8000 meters and descending immediately, and staying there for 12 or 24 hours.

At this altitude, the trouble really starts, and every minute spent up there leads to an inexorable process of self-destruction. We experience loss of sleep, lack of appetite, apathy and often hallucinatory phenomena.

In short... above 8000 meters, you are being consumed. For novices, anything is possible, just remember a few basic rules. The first few days at base camp serve as a thermometer, and by the third day you are often starting to feel good. It is then up to you to decide how to divide up the stages: either use the usual camp sites, or those defined by the terrain. As a general rule, when you can sleep at 6500 meters without headaches, you are ready to go higher. However, it's a good idea to make two return trips to 7000/7500 meters, to test your potential. During these essential shuttles, it's important to stay well hydrated. Now it's time to spend an often uncomfortable night at around 7500 meters, then attempt the summit at 8000 meters. If the summit is beyond that, we try to sleep at 8000.

As for the rest, you need to be prepared to use your brain (or what is left of it) rather than your muscles, because meters, beyond 8500 meters, are more costly. And if I say brain, it is because it has to be sufficiently alert to decide when to descend. If it does not, it is a sure death. Doing an 8000 in good conditions is hard, but with cold, wind, snow or a barometric depression, it turns into a nightmare.

As a general rule, here are a few precautions to take:

  • don't get too cold ;
  • don't get too hot ;
  • cover your head ;
  • stay hydrated, even in bad weather;
  • try to have one hot snack a day;
  • during the trek, do not walk bare-chested;
  • at high altitudes, keep an eye on each other; don't doze off together;
  • never descend alone;
  • set limits for yourself, and look out for signs such as mirages, falling asleep and total loss of appetite;
  • never hesitate to turn back, whatever the pressure;
  • and in all cases, accept the fact that the mountains will always be there.

In short, to evolve at high altitude, you need meticulous preparation, adequate acclimatization, constant and mutual verification, intellectual vigilance at all times, and immediate renunciation in the event of weakness, doubt or danger.

Take a look at our web-conference on climbing Everest and Manaslu.

OUR APPROACH

TRUST, UNITY, SERENITY AND HUMILITY.

First of all, Lhotse, just like Everest, is tamed through a great deal of prior reading, map consultation and listening to first-hand accounts, which allow us to familiarize ourselves with the mountain long before the expedition begins.

Preparation takes over a year. Various aspects such as physical training, mental preparation, thinking about what to do, and technical preparation are tackled with the utmost care.

To optimize our chances of success, in addition to top-quality high altitude sherpas, the most complete safety equipment has been organized, and oxygen will be used at night, starting from camp 3 at around 7300 meters. Initially at low flow, so as to be able to sleep properly, and at maximum flow during the summit push to make the effort more bearable.

The most appropriate food is provided, if possible to everyone's taste. For greater comfort and to enhance normal living conditions, a real camp will be set up at Camp 2, with a kitchen and permanent cook.

It is agreed by all parties that giving up does not in any way constitute failure. Returning to tell the story of your personal adventure can also be a victory over yourself. Any preparation, even the most meticulous, any will, even the most tenacious, can be defeated by the adversity of natural environments whose force is exponentially stronger than the finest human intelligence.

Let the gods bless us and allow us to tread the summit. That is why the best-trained sherpas make a point of devoutly presenting the offering to Sagarmatha, in a simple and moving ceremony as soon as we are settled in at base camp.

Day 18: High camp — Lobuche summit (6119 m) — return to Lobuche

Day 18

We set foot on the snowy slopes of the southern ridge. The route is magnificent, with no major difficulties. There are a few fixed-rope ledges to be climbed up to the final slope leading to the Lobuche Trekking Summit. Beyond, the ridge continues to the true summit of Lobuche, but the difficulty of the progression is beyond the scope of this expedition. Return by the same route to the high camp for a few minutes' rest before continuing downhill to Lobuche.

approximately 5364 m Meals: breakfast – lunch – dinner Accommodations: night in campsite

Day 19: Lobuche — Everest Base Camp trek

Day 19

Once again, we traverse the moraines leading first to the sandy plain of Gorakshep and then to Everest Base Camp. You can see how far we have come in just a few days in terms of acclimatization.

+ 480 m / - 50 m approximately 5364 m Meals: breakfast in campsite – lunch – dinner Accommodations: night in campsite

Days 20 to 53: Lothse ascent (8516 m)

Day 20 to 53

The main stages of the climb are as follows:


Camp 1: 5900/6000 m

Reaching C1 is the most technical part of the ascent. It involves crossing the Khumbu Icefall. The "Ice doctors", sherpas specialized in the installation of fixed ropes along the icefall, have recognized the best passage for the current year. 600 meters of progress on the constantly moving glacier. The camp is located at the entrance to the west combe, at the exit of the waterfall. We limit our stay to two nights at Camp 1 for acclimatization. As soon as possible, we move up to Camp 2, perfectly situated as an ideal starting point for the summit. 


Camp 2: 6400/6500 m

C2 is located on the left bank of the west combe, at the foot of the west ridge. It is a very safe spot, with a breathtaking view of Lhotse. A real advanced base camp, we set up a kitchen tent and a mess tent for optimum comfort. From here, we launch the attempt to the summit. You will spend several nights here before climbing to the upper camps. 


Camp 3: 7100/7300 m

The long ascent from C2 to C3 puts the participants' tenacity to the test. The high altitude slows our progress, but we cannot yet call on the assistance of oxygen. The slope leading up to Lhotse has an incline of between 30° and 45° on very hard, even icy snow. Progress is made along fixed ropes. You will spend two nights at C3 before continuing on to the summit.


Camp 4: below South Col at 7900 m

A long ascending traverse leads to the South Col. We leave the Everest itinerary and head for the Lhotse face.


Lhotse summit: 8516 m

We use oxygen right from the start of the C4. We have to reach the base of the four- to six-metre-wide "Reiss" couloir, whose slope gradually rises to 60° at the top (fixed ropes).

END OF EXPEDITION

For reasons that cannot be foreseen at this stage, such as unpredictable weather, the physical fitness or lack of fitness of participants or other circumstancess (customs formalities, road conditions, traffic, landslides, force majeure, etc.), your expedition leader may have to adapt the program, if necessary, to ensure the smooth running of your trip. He remains the sole judge and the one who guarantees your safety. Activity times are given as an indication and may vary from one participant to another.

The itinerary for all our expedition programs, or the ascent program for our high-mountain expeditions, are given here as a guide only. They are flexible enough to adapt to weather conditions with a few contingency days. In any case, you should follow the recommendations of your guide, who may suggest that you cancel your expedition due to weather, safety or physical conditions.

It is important to remember that this is a truly unsupported expedition, and that anything can happen. Expeditions Unlimited, your expedition leader, your guide or our local teams can in no way be held responsible.

Any costs incurred as a result of a change in the expedition schedule (extra nights' accommodation, extra flights) will be borne by the participants and not by the organizers. "Contingency days" refer to the expedition in the strict sense of the term (base camp/base camp in the mountains, departure point/exit point on a traverse, etc.).

Any early return of the expedition or of certain members only (early success, abandonment, etc.), generating costs for accommodation, meals, changes to air tickets or other activities not provided for in this program, will be charged in full to the participants.

Trip notes

Guiding

YOUR PRIVATE GUIDE

Key to your success on all our expeditions, we systematically use a ratio of one high-altitude sherpa per participant. He accompanies you during the key moments of the ascent and during the summit push. He is particularly experienced at high altitude. We select him for you. He generally speaks English. He may not be with you all the time during rotations between camps, as his role is also to manage the carrying operations to set up the camps.

A summit bonus is also arranged for your high-altitude sherpa, to be paid in cash on site after the ascent. This bonus is due from the moment you leave the last summit camp on your summit push attempt.

Our team of "altitude sherpas" can be made up of several Nepalese ethnic groups, Sherpa of course, but also Tamang, Gurung, Rai, Bothe, etc.


EXPEDITION LEADER


The expedition leader plays an important role in setting up the logistics of the upper camps and implementing the strategy required for success: rotation in the high altitude camps, acclimatization of each participant, study of weather reports to decide on the optimum moment to launch the summit push.


The expedition leader represents Expeditions Unlimited to the group, our partners and local authorities. Mainly based at base camp, he may accompany you to the high altitude camps to oversee the logistics of the expedition. He takes any necessary decisions. His authority is absolute and undeniable. You must respect his decisions, as well as those taken collectiveLY;


From one to five participants, you have a local English-speaking Nepalese expedition leader who has coordinated numerous expeditions over 8000 meters. He can be shared with other expeditions. 


For groups of six participants, an experienced French expedition leader is assigned exclusively to your expedition. 


LOCAL TEAM


For a project involving the ascent of a major Himalayan peak, our team is particularly well-staffed to deal as effectively as possible with the two key issues of an expedition: technical supervision and the carrying of equipment (food, collective and personal equipment). This is an important issue, as it directly affects the success of both parties. As a result of more than 10 years of joint reflection and work, our operation is fully optimized and the tasks entrusted to each person determine their own status. determine their own status.


A base camp manager and kitchen staff will be present at base camp. A cook will be present at Camp 2.


There is a team of porters who help us set up base camp with all the equipment and cooking facilities. Beyond that, the team of high-altitude sherpas takes over. In particular, they help us to set up the high altitude camps and with the carrying from base camp.


Each participant is responsible for carrying his or her own personal belongings and high-altitude food. Collective equipment is carried by the Nepalese team. Our rucksack will weigh between 10 and 12 kg. 

And throughout the program, we will rely on other local skills as needed. Finally, we will have access to personalized weather forecast services and a specialized high-altitude doctor from Ifremmont (see above).

For unpredictable reasons at this stage, like adverse weather conditions, insufficient physical condition of participants, insufficient competencies of participants related to the intended activities, your guide may decide to adjust the intended program and/or activities. At all times, his decision will be final on all matters likely to affect the safety and well-being of the trip.

Difficulty level

Level rated: extreme

This program is intended for experienced participants, who have a high level athlete's physical and mental condition.

It's rated as "extreme difficulty" because of the very high altitude at which you will be climbing. Lhotse is one of the highest mountains in the world: although the technical difficulties are relative, climbing to the summit is nonetheless a difficult and sometimes even dangerous undertaking. Attempts to reach the summit require a high degree of commitment.

This expedition is therefore designed for experienced mountaineers with a good knowledge of very high altitudes (with PD level snow skills _ PD = A little difficult). It is essential to be totally self-sufficient in the mountains, both technically and psychologically. The expedition leader and guides are primarily technical advisors and logistics managers. Under no circumstances can they "pull" a participant towards the summit.

Rigorous training is of course essential, focusing on developing endurance and stamina: running, cycling, swimming, cross-country skiing and, of course, mountain climbing. This training must be regular and begin at least 6 to 8 months before the start of the expedition.

Preparation will continue to be carried out in constant liaison with the organizer and guide. Particular attention will be paid to safety and the management of high altitude hazards. Everest is first and foremost an adventure to come back from and bear witness to. 

High altitude is, of course, the major problem we face. The process of oxygen deficiency (hypoxia) is at its peak when climbing a peak such as Lhotse. Progressive acclimatization is essential to offset this phenomenon as much as possible. During the first few weeks, you need to take it easy, avoid violent efforts and go at your own pace. Although "secondary" symptoms such as migraines and nausea are virtually unavoidable in the early stages, be careful not to ignore them, as they can trigger an oedematous process.

For a relatively long period of time, the body will be subjected to considerable physical effort in a difficult environment, with the added handicap of high altitude. Serious physical preparation is essential for an expedition of this scale: you will need to work on your stamina and endurance, even in difficult climatic conditions (cold, wind).

Beware of carrying: while collective equipment is carried by the sherpas, personal belongings must be carried during the ascent; not doing so at all would be highly detrimental to summit attempts, during which a bag of some weight must be carried, since it will have to contain oxygen cylinders.

On an expedition, participants are confronted with a hostile environment due to its remoteness, cold, bad weather and discomfort, all of which can generate stress. Fatigue can be the cause of mood and relationship disorders. Everyone must therefore show good mood, tolerance and respect, not only towards the members of the expedition, but also towards the local team. The group may split into sub-groups according to individual affinities. Keep in mind that it is the core team that prevails and that, as always in this type of project, the key to success remains the collective and team spirit.

Therefore, participation in the preparation course, the date of which will be specified later, is mandatory. In addition, mountaineering preparation courses as part of our Adventure School can be a serious asset, both to build confidence and to gain autonomy.

To register for this expedition, you will be asked to provide an expedition (mountain climb list)/trek/athlete CV. A hypoxic stress medical test is also mandatory, as is a medical certificate for completing an ascent in the Himalayas.

You benefit, free of charge and for the duration of your expedition, from membership in the 24/7 high altitude medical service set up with our partner Ifremmont, of which we are partners. See below.

If you have any health problems that you feel could compromise the success of your expedition, please let us know so that we can assess together whether they are compatible with this expedition. And we strongly advise you to have a check-up with your dentist before departure, given the length of the expedition and the significant variations in altitude and pressure.

Last but not least, we can provide you with a sports coach and/or a mental coach for the months leading up to your expedition, to help you prepare in the best possible conditions. We have developed remote protocols in this field, just as we have built a hypoxia preparation protocol which we describe later in this document in the chapter devoted to Ifremmont. 

In the longer term, we offer refresher and advanced mountaineering courses as part of our Adventure School, as well as expeditions to peaks at 5000, 6000 and 7000 meters, offering you the ideal progression towards your dream goal at very high altitude.

Technical difficulty

Mountaineering level: Not very difficult (PD+)

In this program, the use of mountaineering equipment (crampons, harness, ice axe, ropes, etc.) is necessary, and the route tackled may involve minor difficulties, whether it be slightly steeper passages in a glacier run, the height of the wall, the commitment of the run or the continuity of effort. Of course, altitude makes everything more difficult. Steep or more arduous passages are all equipped with fixed ropes, so you need to be comfortable with a self-locking handle in all situations. This climb is aimed at participants with previous mountaineering experience and who have already completed climbs of this level. 

This technical rating applies, of course, to normal weather conditions: difficulty can increase in poor conditions, with fresh snow for a rocky route, insufficient or poor-quality ice for glacier mountaineering, etc., and the situation can change radically if the weather is not too bad. Similarly, the situation changes radically, for the same technical level, with altitude, the weight of the rucksack, the lack of equipment for the route on site, the fatigue linked to the approach if it is long, the particularly hostile environment, and so on.

Our École de l'Aventure's three-to five-day mountaineering courses are designed for you, and are the perfect way to make sure you are at the right level.

Meeting point

We meet up in Kathmandu and are welcomed at the airport by our local teams.

Given the diverse origins of the participants on this trip, international outward and return flights are not included in this package. In most cases, we book flights on your behalf to ensure that the whole group arrives at the destination at the same time. We do not charge any fees for these air bookings. Please do not hesitate to contact us. If you book your own tickets, we will advise you on the ideal flight schedule to enable all participants to arrive within a reduced time frame. At the very least, you need tickets that can be modified. 

Accommodations

KATHMANDU AND TREKKING

In a single room in a 3/4-star (***) hotel accommodation in Kathmandu.

During the trek, we will be staying either in individual tents or in lodges. Lodges in Nepal are of very random comfort. Lodges can resemble a refuge or sometimes our local B&B. Most are family homes with double, triple or dormitory rooms. Toilets and showers are always separate. It is important to check that the water is not heated with wood, as this contributes to deforestation. Most of the time, water is heated with solar energy.

BASE CAMP

At base camp, we stay in individual tents.

As a base for several weeks, it needs to be as comfortable as possible, to enable us to recover properly on our return from the altitude camps. It should also enable us to cope with periods of bad weather in the best possible conditions. Each participant has his or her own individual tent with a comfortable mattress. A heated mess tent is the main living area. Tables and chairs are permanently installed. We also have a shower tent and a toilet tent (solid waste is disposed of in drums).

HIGH ALTITUDE CAMPS

During the ascent, at the altitude camps, we have an altitude tent for 2 people, and even 3 people at the last camps. 

At C2: we have a kitchen tent and a mess tent.

Hygiene & laundry

Toilets: The base camp is equipped with toilets and toilet paper. Make sure you wash your hands with a hydro-alcoholic gel (available from your personal pharmacy) after each use of the toilet. For the higher camps, we recommend that you take a bottle with you to urinate in at night, to avoid having to go outside.

Daily hygiene: a basin with soap and water is available at the entrance of the mess tent. Water for washing hands and face; do not drink. 

Showers: hot water available (request from kitchen). Showers should only be taken on sunny days to avoid catching cold! 

Laundry: (cold) water and basin to be requested from the kitchen. Bring biodegradable products only.

Meals

KATHMANDU AND TREKKING

On arrival in Kathmandu, a welcome dinner is offered on the first evening. Similarly, on your return from the expedition, a farewell meal is provided. 

In the towns, there are many small (and large) restaurants where you can sample typical local cuisine. With the exception of Kathmandu, breakfasts and evening meals are prepared by the lodge's kitchen staff or cooks and served in the lodge's dining room or mess tent. Depending on the profile of the stages (length of the day's walk and/or presence of water), midday snacks will be served hot or cold in the form of picnics.

BASE CAMP

All meals are prepared by the kitchen staff using local ingredients, including rice, pasta, lentils, potatoes, vegetables, eggs, a little meat, etc. They are served in a private tent. Hot non-alcoholic beverages such as tea and coffee are provided free of charge. We recommend that you stay hydrated at all times. 

HIGH ALTITUDE CAMPS

At C2, a cook will be on hand for the duration of the expedition. At altitude, you often have to force yourself to eat. The use of freeze-dried food is almost unavoidable. But such dishes, appetizing in the valley, quickly become a source of disgust in high altitude camps. During the preparation course, we bring a sample of lyophilized dishes for you to taste, to indicate your preferences, which we do our utmost to respect (depending on the stocks available at the time of final purchase). You can also bring along a few of your favorite dishes (if you have any)or small snacks that give you pleasure (cold meats, cheese, etc.), or energy bars as the ones on offer locally are sufficient but basic, and so on. Be careful with the weight – we are talking about a kilo in all! 

Each tent has a stove for melting snow (MSR Reactor type) and making water for freeze-dried food and hot drinks. The necessary gas cartridges are supplied.

HYDRATION

Take along tablets (such as Hydroclonazone, Micropur or others) to disinfect the water you put in your water bottle, depending on the source and on the advice of your guide. It is sometimes possible to buy purified water and fill your bottle without having to buy bottled water. You can also buy "mineral" water in the towns (not included in the price), but as you know, it has a poor environmental performance. So we do not recommend it.

Besides, glacier meltwater contains no mineral salts, which is partly compensated for by the soups and other meals you' will be eating. But if you only drink tea or coffee made from glacier meltwater, or just water in your water bottles, over a long expedition, you will hydrate less well, risk gastric problems and, ultimately, deficiencies that will tire the body. To counter this problem, it is a good idea to pack mineral tablets in your luggage at some point, to supplement your water bottle. Two or three tubes of ten tablets are all you need.

Transfers / Transport

All transfers are by private vehicle. 

For a number of reasons, we prefer trekking to base camp: the progression designed for acclimatization allows us to prepare both physically and psychologically for the ascent. It is also the ideal time to get to know the team and start building a sense of group spirit and cohesion. 

The return journey is also planned as a trek. However, for an additional charge, you can also take the helicopter on the return journey. 

Group size

The group is composed of 1 to 10 participants maximum. The number of participants is deliberately limited to allow for greater immersion, to avoid embarrassing our hosts, and to develop freedom and flexibility. However, the maximum number may be exceeded if the last person to register wishes to travel with one or more other people. The services will not be modified, and the conditions of the trip will remain the same.

Equipment

COLLECTIVE EQUIPMENT

All logistical equipment is provided, including individual tents at base camp with mattresses, mess tent, shower tent and toilet tent, as well as all collective and individual cooking equipment. At altitude, tents, stoves with gas cartridges, ropes and anchors.

INDIVIDUAL EQUIPEMENT

Personal equipment is not provided. A full list is given later in this document. It will be refined with us during the preparation course and up to the moment of departure, depending on your questions.

High altitude sleeping bags, full-body down suits and/or good-quality down jackets are expensive items that you may not use frequently. We can rent you this specific equipment for the duration of the expedition. You must then return the equipment cleaned and in the condition in which it was given to you (deposit required). The rental price will be communicated to you on request. The cost of transport remains your responsibility, unless you pick it up at the agency in Lyon.

OXYGEN OR NO OXYGEN

For safety's sake, high altitude sherpas always use oxygen, even at reduced flow rates.

The vast majority of participants in Lhotse expeditions take oxygen from Camp 3 (7300 m), and some as early as Camp 2 (6500 m). We therefore include in your package the oxygen supply from Camp 3 (5 cylinders, regulator and oxygen mask). Cylinders and equipment are transported to altitude camps by altitude porters.

If you wish to use additional oxygen before Camp 3, you will need to ask your expedition leader and/or sherpa as soon as possible during your expedition, and additional cylinders will be charged extra. Oxygen cylinders not included in the package must be paid for on site.

That said, we are one of the few organizers to allow our participants to attempt the summit without supplemental oxygen. Our experience shows, however, that only the most experienced Himalayan climbers manage to achieve this feat (between 1 and 2% success rate every year). The organization, and in particular the ratio of "1 high altitude sherpa to 1 participant", means that the pace of ascent can be slightly different and more personalized. So we can have participants in the same group who need oxygen and others who do not.

If you choose to attempt the climb without the use of oxygen beyond Camp 3, then you need to talk to us as soon as possible to fine-tune your acclimatization. Your choice will depend on the agreement of your expedition leader and/or your sherpa, who will assess your fitness during the first rotations. Please note that if you choose not to use supplemental oxygen for your ascent, no refund will be given. For safety reasons, one oxygen cylinder per participant is provided at Camp 4, whether you use it or not. 

You then have two options, starting from Camp 3 (7300 m) during the summit push: 

  • You don't need an oxygen cylinder: the "purist" option par excellence. It allows you to move forward without adding extra weight (4/5 kg). But if you become too tired or slow, you have no option but to turn back, whether your sherpa tells you to or not, and return to Camp 2. The summit attempt is over, there will be no more.
  • You take at least one oxygen bottle with you if you need it to complete the climb: it means extra weight in your rucksack (4/5 kg), and it's up to you to use it or not, at any point during the summit push.

SECURITY AND COMMUNICATION

We have a minimum of one Iridium satellite phone for the group, which is used for logistical, weather and safety purposes only. Under certain conditions, participants may make use of it. For private use, please contact us.

The camps will be permanently linked by radio. Expedition leader, participants and high-altitude sherpas will also be able to use them. 

The expedition will have a hyperbaric chamber at base camp, and a full pharmacy, though lighter, at the upper camps.

The group will be equipped with a Garmin Inreach beacon, enabling you to communicate freely and without restriction with your friends and family, wherever you may be on the mountain, as well as sending tracking and safety information. It is on this beacon that you will receive weather forecasts and that we will communicate together regularly.

At the same time, we will provide live coverage of the expedition for the general public, including a logbook and photographs, enabling you to share your adventure with your community. To this end, and if the base camp is not equipped with wifi or 4G, you can also use an IridiumGo system to send your photos. These systems are simple to use, but require a few tests before departure, which we will carry out together.

In addition, at the time of writing, all participants are free to bring any systems they have. We just need to be able to declare them to our contacts, so please let us know in advance.

Please note: in order to preserve the serenity of this expedition and the privacy of the participants, we ask you not to communicate with the general public during the expedition. You are, however, free to send information about yourself to your private sphere. By registering for this program, you accept this essential clause to protect the privacy of other participants in a project of this scale, where important issues of image, physical risk and financial considerations (sponsors, etc.) are at stake.


Our commitments to sustainable development

Our commitment to a better planet has been a reality since the beginning of our story but we always need to do more and better. Please find out more about our charter and our commitments in terms of sustainable development. We have drafted our charter and take action through six themes on which we act as concretely as possible, most often with you: social equity and cultural respect, preservation of water, waste management in expedition, protection of biodiversity, raise public awareness on these subjects and finally, the optimization and recovery of CO2 emissions.

Regarding carbon emissions, most of which are due to air travel, we calculated and communicated in 2018 on the carbon footprint of each of our programs, expressed in tonnes of CO2.

These calculations made us aware of the importance of the total carbon emissions generated by our activity. Also, we have committed in 2022 to a carbon reduction that we believe is unprecedented in the tourism industry, aiming to reduce the total emissions of our activity by 5% per year, taking 2019 as the reference year (3,430 tonnes of CO2). This commitment is in line with the trajectory of the Paris climate agreements of 2015, the current benchmark. Thus, in 2030, we will not entitle ourselves to exceed 2,160 tonnes of C02 and until then, each year, as soon as the carbon footprint budget is reached, we will stop taking any reservations for the current year. Thus, our maximum “carbon” budget for 2024 is 2,950 tonnes and for 2025, this budget will be reduced to 2,800 tonnes. And so on until 2030. To find out more about all of our calculations and our commitments in terms of reducing our carbon emissions.

In addition, since 2019, we have been encouraging you when you book for your journey to contribute with a donation to an independent NGO, among the two we have selected that share the commitments made in our charter. We matched the amount of this donation to this program's carbon footprint. Thus, the journey you are considering generates 3,69 tons of CO2, which corresponds to a 100% donation of 111 for an estimated value today of €30 per tonne of CO2. This donation remains of course optional and you can decide to give between nothing and 100% of this amount. Since 2019, including covid years of 2020 and 2021, we have been able to collect thanks to you nearly €7,000 for these associations.

Please do not hesitate to come back to us with any questions you might have regarding this carbon footprint mechanism, our other sustainable développement commitments or even to share with us your experience through a chat or a mail at contact@secret-planet.com.

Expedition leader

We rely on the most experienced high altitude expedition leaders. They are part of our close community and co-opt each other. They know each other well and respect each other.

For this expedition, the expedition leader has not yet been formally appointed, but should be shortly.

In addition to their exceptional expeditions experience, our expedition leaders have the know-how to optimize the expedition's chances of success, both in terms of group management and in terms of the pace at which the group builds up its strength and progresses in altitude, key elements in this type of expedition.
