This mountainous stage begins with a long climb to the Pas du Grand Échaillon, which continues up the Ravin de Pissenible to reach the Col de la Bataille and its viewpoint. The path, which is almost level on the flank of the Roc de Toulau, then climbs to the panoramic viewpoint at the Croix d'Ambel, before descending after the Pas de Garde to the viewpoint at Pierre Plate and crossing through Omblèze. It climbs to the Col des Ayes and then continues to the Col d'Anse, from where it descends to the hamlet of Ansage before reaching the car park

First stage of the circular route around Omblèze in the Southern Vercors. This route begins with a visit to the Chute de la Druise, one of the most beautiful waterfalls in the Vercors, which plunges 70 metres from the bottom of a narrow gorge. After passing through the Gervanne Gorge, you come to the charming little Pissoire Waterfall, followed by a crossing of the Gueulards Canyon, a unique geological feature that inspires both unease and delight, before reaching the small, isolated village of Léoncel and its 12th-century abbey, with its old-world charm, which offers hospitality in a discreet manner.
