Extend your Chamonix
course, to maximise your acclimatisation
is a course extension, for those on a week
long course such as Mont
Blanc Summits or the Matterhorn,
who wish to kick start or enhance their acclimatisation.
You arrive in Chamonix on the Saturday afternoon
or evening on any flight that suits, and have
accommodation in town for the night, before
a choice of self-guided or guided acclimatisation
day options to suit the following day.
run these Acclimatisation Weekends in Summer
(from June to September), every week of the
season before a scheduled course. On most
weeks over half of clients on a Mont
Blanc course opt for this,
as the guiding on the scheduled course is
five days, so if weather dictates an earlier
ascent, you will not be very acclimatised
without considering one of these extensions.
those who opt for guided activities on the
Sunday, we always ensure that they are over by mid-afternoon
to allow you to descend and return to Chamonix
by 16:30 on Sunday, so that you can freshen
up for the 17:00 main course briefing.
this weekend is a case of stacking some of
the odds in your favour. We don't guarantee
that you will be fully acclimatised, or that
it will ensure you summit your main peak in
a course after the weekend, nor is it any
training substitute. It is simply one tool
that many choose to increase their chances.
If you really want to acclimatise well, book
a two week course e.g. Mont
Blanc Achievements or Mont
Aiguille du Midi cable car is closed for weather or maintenance,
and you are looking for a self-guided
option for activities on the Sunday, here are two obvious alternative
options to consider;
1) Skyway 3500m - take the bus from Chamonix
Sud (08:30 first bus) to Courmayeur, and
catch the Skyway lift to Helbronner. This
is the equivalent of the Aiguille du Midi
on the Italian side, and to stay the day
at that altitude would be great acclimatisation.
2) Grands Montets 3295m (currently closed following a fire, hopefully re-opening in 2025) - catch the free valley
bus to Grands Montets in Argentiere, and
ascend to the the top of the cable car.
This is slightly lower than the Skyway,
so is definitely a second option.
How long should you stay up there? All day
long! Go up on the first lift, and descend
as late as possible, in time to get back
for the 17:00 course briefing.
are listed in the column on the right, and
they show the live availability from our secure
online booking system. When you book online,
you receive immediate confirmation, your Alpine
Information Booklet, course specific kit list
the Saturday you travel out to Chamonix, where your accommodation
is provided for the night. Below are the options for activities
on the Sunday, so you can select a method of acclimatisation
which suits you best. Note your preference on the course
booking form (select the acclimatisation weekend date
below your course option, and detail your activity option
in the 'Notes for Icicle' section on the form). The night
of accommodation is guaranteed from the time of booking.
Let us know at the time of booking if you prefer the self-guided
option (i.e. just the £75pp for the night), or of
you wish to add a private guiding supplement to your invoice
(i.e. £75pp for night + guiding).
Supplement for private
is the most popular choice for the weekend, to allow
you to undertake a self-guided day. Below is an
outline of a frequently used itinerary for the day,
that obviously is subject to your experience, weather
and the conditions. It is only a suggestion.
£390 (up to 2 clients)
Enjoy an extra day of high mountain guiding, from
one of the top cable cars (Aiguille du Midi or Grands
Montets) for a warm up route such as the Pointe
Lachenal or Petite Aiguille Verte.
you get up quite early, you can beat the queues,
and extend your cable car pass by a day (c.15€
extra) and ascend to the Aiguille du Midi 3842m.
This is the highest cable car in the Mont Blanc
massif, and you are whisked up to the top in just
over 20 minutes. It's worth spending 3 or 4 hours
up there to really kick start the acclimatisation
process. There's viewing terraces, cafes, toilets,
and even a restaurant, but just doing the tourist
'thing' will take a good few hours, and it's a photographers
£250 (up to 6 clients)
Ascend the highest trek peak in the Mont Blanc massif
in a day. Mt Buet 3109m involves trekking 1800m
of ascent, usually 4 hours up and 3 hours down.
A big hill day, but hugely rewarding.
around lunchtime, you could descend to the mid station,
at Plan d'Aiguille, and hike across to Montenvers.
This balcony trail walk only takes about two hours
maximum, and as it's over 2000m, you are boosting
acclimatisation still, without using much precious
energy. When you reach Montenvers, you can use your
cable car pass (it covers all the uplift in the
valley) to catch the train back down to Chamonix,
and you'd be back in plenty of time before the course
into & safety briefing at 17:00.
£250 (up to 4 clients) Many train for courses
by running, and Chamonix is the European mecca of
trail running. Join one of our experienced ultra-trail
guides for a c.20km run on one of the most classic
trails above the valley.
is acclimatisation so important?
will already be aware that acclimatisation is essential
in the mountains. It takes an average person about
10 days to get 80% acclimatised, and five weeks
to increase this to 95%. In other words you will
never be fully acclimatised for a week long Alpine
course, but every day building up your acclimatisation
options are all conducted around 2000 - 3800m, at
which altitudes you will really develop stimulation
of the red blood cell production. These are the
blood cells that carry the oxygen around your body.
abide by the rule of climb high and sleep low, but
don't expect to get a great nights sleep at your
first night at altitude. Some people notice they
sleep lightly the first night they are in Chamonix
gaining height slowly and carefully you are maximising
your chances of acclimatising further during your
stay in the Alps, to make a safe and realistic attempt
on one of the larger summits.
You can get flights and transfers to arrive in Chamonix
at any time on Saturday that suits you. The course
accommodation will be available for check-in's from
16:00, but equally don't worry if you get an evening
flight, as you can check in later too. Our objective
is to be as flexible as possible for these weekends,
to make them as accessible as possible for the maximum
number of clients. If you check in at 16:00 (sorry
we can't get you in earlier, as the flats are still
occupied, then being cleaned), our resort team can
advise you on kit and weather for the following
day. The accommodation is self-catering, so
in the evening you can cook in or eat out at one
of the restaurants in town. Most people get an early
breakfast you follow your chosen activity for the
day. For all of the guided options, the normal meeting
time is at 08:30am, so ensure you've adjusted your
watches and alarms! For those attending a guided
activity, meet at the course meeting point (see
Course Instruction Booklet for map) at 08:30 ready
to set off straight away, with any snacks or lunch
that you require for the day. There is a great bakery
close to the accommodation, which sells a wide choice
of sandwiches and patisserie. All the activities
aim to descend and return to Chamonix in time to
freshen up before your main course briefing at 17:00,
which includes equipment checks, and information
for the week.
NOTES: Where possible we follow itineraries. Mountain
adventures are weather and conditions dependant, so occasionaly
we are forced to alter the plans. If this is the case,
suitable alternatives are offered. Please use this itinerary
as a guide to the types of route / activity you attempt.

Note that this is the basic option (Option 1)
and is room only. All guided options pay a supplement
on top of this price, as above.
that all the guided options for the Sunday are for private
groups, not collectives that are matched together, and
the prices are in total. If you want guaranteed guiding
on the Sunday, you need to book a private guide.

I just take this opportunity to say
thank you so much for the weekend guiding.
I got my bearings, learnt about the
region, and gave me strong hill legs
for the rest of the week. Thanks John

nights in huts?
options detailed on this page are for those seeking accommodation
in Chamonix on the Saturday night, and either self-guided
or guided activities on the Sunday.
If you are determined
to maximise your acclimatisation, another option to consider
is to check in to our accommodation at 16:00, then to
catch one of the last cable cars up the mountain to stay
in nearby mountain huts.
Examples of these are the Plan
d'Aiguille hut (10 mins from the Midi middle station),
the Bellachat hut (45 mins walk from the Brevent cable
car), Flegere hut (next to the Flegere cable car), or
the Montenvers hotel (next to the terminus of the Mer
de Glace train).
You could book all these huts directly
yourself from their websites. All these options are at
around 2000m, and do not require any glacier travel or
mountaineering skills to access them, as essentially they
are trekkers huts.
If you are determined to acclimatise
well, an extra hut night might really make the difference!
