Baisse du Basto

Highlight • Mountain Pass

At the Baisse du Basto you approach 3,000 meters in altitude. By doing so, you increase the chances of encountering ibexes. They are not uncommon at this height.

The climb is steep. Take your time.

You are getting closer to the Vallée des Merveilles, that is undeniable. This lake alone is a gem. The reflection of the mountains in the deep blue of its waters contributes to the enchantment.

Beautiful tour that also invites you to take lots of breaks. The hut at the destination is in a great location, has a lot of charm, but is very basic (e.g. no showers, no electricity for guests)
