Anyone wanting to climb here should have absolutely no fear of heights and not be afraid of the very exposed climbing sections on greasy rock! Not all sections are secured with wire ropes.

Very steep, loose gravel, official XC E-MTB trail. If you like pushing your bike for a few hundred meters, this is a great trail!

Please note that contrary to what we can read on many websites, bivouacking is strictly prohibited (protected and/or private area) throughout the massif.

A great classic of Lake Annecy. Beware of the crowds and the heat in summer. A departure at dawn is more comfortable. Conversely, in the off-season, beware of the snowfields still possible until June and the cool temperatures until mid-June and from September.

Basic riding skills are not enough for this tour! It is far too steep to ride uphill. Going downhill you need a full suspension bike with a lot of suspension travel and very good riding technique. I don't think that's suitable for mountain biking.
