This is a great classic for hikers in the region. In the summer it gets quite crowded. I recommend the southern slope, from the Pré du Four parking lot.

It is possible to do the Crête des Crocs tour by following the path at the bottom of the cliffs. You will have to pay attention to the cairn which indicates when you must leave it to reach the ridge and switch to the other side. Be careful, the path to go back down includes a technical passage that can be avoided by passing the rocky bar while staying on the ridge.
