Last updated: 17/10/2023

price from 1790 € per pers.

The price given is for a group of 6 to 12 participants. One month before departure, before payment of your balance, we will give you the final number of participants. NB : For "open" groups, in accordance with our general sales conditions, a minimum of 6 participants (addition of individual registrations) is required for our departures to be guaranteed. They are cancelled or confirmed at least 30 days before the scheduled departure date.

This is the Authentic in the original sense of the most famous of treks.
The more alpine, more mineral, more difficult northern part will be absorbed by fresh bodies from the very first days.

All the climbs on the program are NORTH-facing, so in the shade, which is an undeniable advantage!

What's more, you'll be physiologically and mentally relieved before tackling the second part. All in all, an optimized success rate.

We use local mountain guides with excellent knowledge of the route. However, their level of English cannot be guaranteed. Groups are opened to french and english speaking walkers (You will not be with english speaking persons only). Do contact us for more details.
