The route, zigzagging between two cliffs, leads gradually up into the heart of the Grande Combe. The Pas de Siara gives a glimpse of the south-alpine lawns of the Trois Becs before a gentle descent into the beech forest.
The path winds through the lush Grande Combe, becoming increasingly narrower until it reaches the alpine pasture of Pré de l'Ane.
You can make a return trip to the Pas de Siara for a glimpse of the sub-alpine meadows of the Trois Becs, where ewes from neighboring valleys graze in summer.
2nd return section of the loop: follow the signs for the Bois Vert sheepfold, where cattle may be present during the summer months.
Next, a magnificent viewpoint at Porte de Barry (Bourdeaux and Drôme provençale), a wide, shady path towards Les Berches, then on to the refuge des Princes (possibility of a stopover and bivouac). Undergrowth trail leading to a meadow: view of Pas de l'Echelette and Pas du Fau (Roche Colombe). Return along the horse park fence to the eco-guards' office and adjoining parking lot.
