The access is very well signposted, and you can do a lovely loop hike, starting from Saint-Même-le-Haut, or from Saint-Pierre-d'Entremont for the more adventurous. At the end of winter, the water level can be very high.

The path to Lac de crop is somewhat steep at places, but it is well maintained and well marked. The view of the lake is truly rewarding. Highly recommended.

Magnificent lake! Accessible to all! As a bonus, you'll find ibexes and a few marmots if you're lucky. For the more courageous, you can climb to an altitude of 2,900 m by continuing on the path with a magnificent view if the sky is clear!
