Departure from Oris-en-Rattier (Isère)
The Sommet de la Cavale does not claim to be on a par with its imposing neighbour, Le Coiro, which is 460 m higher. However, it remains a worthwhile destination, both for its wild and airy setting and for the beauty of the surrounding landscapes.
The fairly sustained climb up this long ridge is richly rewarded by the magnificent viewpoint offered by the summit, which provides breathtaking views of the Valbonnais, Dévoluy, Matheysine and Vercors massifs and the high peaks of the Écrins.

4h 20
Moderate
Departure from Saint-Honoré (Isère)
Seen from Lake Charlet and the climb to Tabor, the Sentier du Diable, which winds its way up the south-western face of Pérollier, is impressive, and its name deters many hikers from taking it. However, it is a pleasant trail with a fairly steady climb and is not particularly dangerous. We take it here to climb Pérollier (2,183 m), the third highest peak in the Tabor massif, and make a loop via Lake Charlet for the return journey.
