The Eiger is one of the most sought after summits in the Alps and a formidable challenge. If you have previous alpine experience and good physical fitness, it is within your grasp. We aim to climb this famous peak towards the end of the week, after a suitable preparation in and around the Chamonix valley.

Normally climbed via the Mittellegi Ridge with a descent via the South Ridge, this is a long and technical climb – for fit climbers only – but worth it to get to the top of this world famous peak.

We will stay in the famous Mittelegi hut followed by the Monchsjoch hut on the way down.

A word on the weather:

The climbing season runs from mid June to mid September and between those dates there is no better or worse time to attempt the climb. The beginning and end of the season can be snowy/ cold, and the middle months can be busier and the hotter temperatures can cause afternoon storms.

Summit success varies from season to season but remains consistent throughout the different months. If the weather shuts us down, we will endeavour to find the closest mountain in the area with better the weather, and thanks to our location we are generally able to find an equally beautiful alternative within driving distance in France, Italy or Switzerland.

Who is this for?

This course is for keen, fit mountaineers with previous experience on AD terrain. Stamina, balance, and concentration are a must! Our Chamonix Classics, Alpine Skills or Private Guiding courses are ideal preparation.

Accommodation and huts

Our Eiger courses are based out of our Chalet Pele which is located perfectly in Chamonix centre for the first 3 days. Rooms are normally on a twin shared basis with others from your course and all rooms are en-suite. The chalet has WIFI, a lounge and spacious dining area as well as a fun atmosphere. There are often other like minded people staying in the chalet who are on various other courses that we offer. Chamonix’s main high street is a short 5 minute stroll away with plenty of restaurants, bars and cafes as well as mountaineering shops for any last minute rentals or purchases.

What to expect from mountain huts

They are basic but comfortable. They can cater for vegetarians. Food is usually on a set menu basis (3 course in the evening, hot drink and bread/jam/cereal for breakfast). Often there is no running water and you have to buy water to drink and wash with (no showers). You can usually buy tea, coffee, wine, beer, soft drinks, chocolate bars and snacks.

Sleeping arrangements are normally dormitory style bunkbeds (eg 6 people on the bottom, 6 on the top) with blankets or duvets. No sleeping bags are needed, rather a ‘sheet sleeping bag’ should be brought. The huts provide slippers for wearing around the hut. On this course we ask the hut guardians to provide a packed lunch for the team each day.

You can expect a good atmosphere and a stunning view!

Typical Itinerary

We climb the Eiger via the classic Mittellegi ridge. This is a long climb (10 hours or more) on delicate terrain – snow ridges, rock ridges and scrambling. Like the Matterhorn, this mountain also requires fairly dry conditions for an ascent.

The itinerary is flexible, and weather / condition dependent, but here is a guideline of what to expect.

We meet Sunday evening to go through the weather/conditions and plan for the week. You meet your Guides and can ask them any questions

Warm up on the cosmiques aretes or similar route.

Tuesday – Wednesday:
2 days climbing around, and overnighting in, the Torino hut. Typical routes would be traversing the Entreves, the Tour Ronde and the Dent du Geant. This is the final preparation for the real thing, and great routes in themselves!

Drive to Grindeward (we organise this) and take the famous mountain train and walk to Mittelegi hut.

Friday – Saturday:
Climb the Eiger and descend to the Monchsjoch hut. We have a spare day built in to this itinerary to deal with any bad weather and maximise our chance of success.



To maximise your chance of summiting the Eiger it is important to get as fit as you possibly can. Good fitness will also make it more fun and less exhausting! The process of training for your goal will help you focus on your goal and having a goal will help you focus on your training. So all in all training is good!

Mountaineering is all about being able to exercise at a moderate intensity for many hours (typically 5 to 12 hours) and your training should reflect this. Probably the best training is going on long days hill walking as this simulates the real thing as closely as possible and prepares the mind (exercising for long periods in poor weather requires mental strength!).

However not everyone has the opportunity to do this and so alternatives such as jogging, cycling and gym workouts are good.
The focus should be on training Cardiovascular Endurance for long days in the mountains, and upper body strength for climbing.
For cardio cycling/running/rowing machines are much better than weight training. Try and exercise for up to a couple of hours at a time, 4 times a week. For climbing, core stability, flexibility and balance are as important as strong arms and shoulders. Don’t just lift weights!

Try yoga, swimming, pilates etc too. Remember to build up your workouts over time. If you are not used to exercising much, your muscles and joints need time to build up to avoid injury.

Try and choose an activity that you enjoy and keep a note of what you do and your times – this really helps with keeping the motivation up. If you are not used to training then your local gym will be able to advise you on a plan and schedule to help you achieve your goals.

Training does not work overnight! The fittest athletes train as part of their lifestyles and have been doing it for years.
Consider training for a good couple of months before coming out to the Alps.

The Effects of Altitude

As one climbs higher the air gets thinner and so there is less oxygen in each breath we take. The higher we go the less oxygen there is. This makes exercising much harder work than at sea level and so we have to slow down to help compensate. Because we have slowed down, we may feel colder.

Because there is less oxygen in the air as we get higher, this can lead to ‘altitude sickness’ or Acute Mountain Sickness which is like the worst hangover you have ever had (headache, nausea, weakness, fatigue, dizziness) and can develop into a very serious and even fatal (in extreme cases) problem.

To avoid these problems, enjoy the climbing and increase our chances of summiting we need to acclimatise by spending several days and nights at progressively higher altitudes, so our bodies can adapt. This is a very important part of our preparation.

Booking info

To find out more about our course, availability, or to ask any questions, please get in touch through the website or by phone on +33 (0)845 527 58 12.

We take a 30% deposit to secure your place on one of our courses, and we ask for the balance to be paid 10 weeks before the course start date.


We strongly recommend getting specialist travel insurance that covers cancellation, medical and mountain rescue.

Make sure that it covers glaciated mountaineering and climbing. We recommend the Dogtag (www.dogtag.co.uk) – they have comprehensive policies and a good reputation.

Getting to Chamonix

It is best to book flights and airport transfers well in advance of your departure.

Easyjet have many cheap flights to Geneva from all over the UK. Swiss Air have cheap and convenient flights from London to Geneva.

Booking a place on a minibus airport transfer service is by far the best way to get from Geneva airport to Chamonix (it takes about an hour or so, is cost effective and is a door to door service). We can book your airport transfers at a competitive rate – just email us with your flight details…

There are several cash points in Chamonix /Grindlewald and Maestro/visa/mastercard are all readily accepted. In mountain huts, however, you need to have cash (Euros / Swiss francs) to pay for any incidentals.

Confirming bookings

We need a minimum of two climbers to confirm this course. Your booking will remain pending if you are the first to book onto a course and we will send you a confirmation as soon as a second books on. We recommend not booking flights till the course is confirmed. We will confirm the course at the latest 6 weeks before the start date.

Will I definitely make it to the summit?

In short, no. Whilst we will always strive to get you to the summit safely, sometimes the weather or the conditions of the mountain don’t play ball. When there is precipitation, high winds and low visibility for example, we cannot guarantee reaching the summit and will sometimes recommend an alternative. Each Eiger course has a lead guide. The lead guide will always conduct a meeting with the clients and other guides the day before the Eiger ascent is due to begin (Usually the evening before we leave Chamonix for Grindelwald). During this meeting the latest weather forecast, conditions of the mountain, and the clients own ability to reach the summit will be discussed. Clients and guides alike will voice their opinions and/or concerns at the time and then decide how best to proceed. We fully trust our guides to make these final decisions based on their years of experience on the mountain. They are entrusted to make the final call and the client must accept any decision made. All decisions will have client safety as a top priority.

What type of boots do I need for the Eiger?

You will either need B2 or B3 mountaineering boots for the Eiger. All mountaineering boots are graded in a B1, B2, B3 system.
This will greatly depend on the conditions of the Eiger. If it is dry and warm B2 boots will be suitable. If it’s a little snowy and cold, B3 boots will be required. Both can be rented locally.

Can I store my belongings with Adventure Base when I’m in the huts?

Yes. From when you arrive till when you depart you are allocated a room in our Chamonix chalet and this will not be occupied by anyone else during that period. Please note rooms are usually allocated on a twin share basis, in most cases sharing with others from your course.

Is there wifi in the mountain huts?

No. All mountain huts are fairly basic and do not have access to WIFI. Some huts will have phone signal and some will even have 3g signal but we cannot guarantee this will work at all times.

What are the mountain huts like?

The mountain huts we use for our Eiger course are fairly basic but comfortable. You will sleep in dormitories on a shared basis, usually 6-8 per room. The huts provide breakfast, lunch and a 3 course dinner. In Chamonix we tend to use the Refugio Torino and Cosmiques Refuge. For your Eiger climb we use the Mittellegi hut and the Monchjoch hut.

What kind of fitness level do I need?

You need to be able to hike for 6-8 hours at a moderate pace. Mountaineering is all about having good cardiovascular endurance to be able to continue being active for long periods. As well as this you will need to have a good head for heights and good overall body balance.

Do I need to have previous experience?

Yes. If you have previous experience on alpine grade AD terrain with good physical fitness, the Eiger is within your grasp. We aim to attempt the Eiger climb towards the end of the week, after suitable preparation and acclimatisation. You must have a good head for heights and a good level of balance control whilst walking along narrow exposed ridges.

What size backpack should I bring?

Your backpack should be no bigger than 50l and no smaller than 30l. It is important that your backpack has an ice axe strap to stash your ice axe when you are not using it. Your backpack must also have a rain-proof cover.

What are the guides like?

All of our guides are highly experienced. They have all been hand picked by us over the many years we’ve been in the guiding industry. Our guides all speak a good level of English and are very attentive. Their primary role is to get you to the summit safely, but they also provide a high level of customer service along the way and are very interesting people to spend time with. They like to share their knowledge of the mountains and their experiences, so don’t hesitate to ask questions and pick their brains. Lastly, they know the routes on the Eiger like the back of their hands and this is the most important thing when it comes down to making key decisions in the mountains and providing the safest experience for our clients.

What will we do if the weather is bad?

This depends on a few factors and how bad the weather actually is. Should the Eiger be unsafe, we will study the conditions on other peaks in the Alps, in the Monta Rosa region for example. Should conditions be a lot better elsewhere, we will propose this to you as an option.

Strong high winds – this means reaching the summit is unlikely. High winds on the ridge will put us in danger and therefore we will likely look for an alternative.

Precipitation – When it snows on the Eiger it usually means a summit attempt will be very difficult. The route to the summit of the Eiger is a rocky ridge and if its covered in snow and ice it becomes a treacherous task. Route finding in a snow storm is also unsafe.

Whiteout – A cloudy whiteout will make a summit attempt difficult. Route finding in a whiteout is generally unsafe and therefore we will encourage you to consider an alternative.

Heat – This doesn’t tend to offer up any problems. When the Alps is hit with high temperatures and dry conditions, the Eiger is in good climbing condition.

How many clients per guide?

For the three training days at the beginning of the week we have a 2 client:1 guide ratio. For your Eiger attempt our ratio is 1 client:1 guide.

“Standing on top of this historically tortured peak is an experience you will never forget – reading the White Spider by Heinrich Harrer is a must during your training. Feel the history and challenge yourself to make it to the summit!”
