RANDOPARC CHEMIN DES CRÊTES

One of the park's emblematic hikes, called the "Chemin des Crêtes", starts in Aillon-le-Jeune. It's a 14 km loop, offering around 4 hours' walking with a 600 m vertical drop. Following rocky slopes and grassy paths, hikers traverse this varied landscape until they reach the crests. At this point, the climb offers magnificent panoramic views. The route is relatively easy and leads all the way to the Carthusian monastery.
