To get to the start: Coming from Le Dévoluy, just after the Pont de la Baume, turn right onto the D217 towards Monestier-d’Ambel. The Gillardes car park is located about 1,500 m further on, on the right
(S/E) From the car park, after crossing the road, head west to join a path marked in yellow and follow it towards Les Gillardes. The marked path heads north and climbs above the resurgences.
(1) Ignore the footbridge over the Souloise and climb a few hairpin bends, keeping to the left bank. Shortly after a hairpin bend on the right, you’ll reach a fork in the path: take the right-hand branch which goes straight on... When the path joins a wide track, follow it north-eastwards.
(2) At a hairpin bend to the right, leave the track and take a path on the left. Further on, cross the track you left and head towards the canyon, which you reach via a few steps.
(3) Retrace your steps, head down to the left to reach the footbridge and cross the Souloise. Follow the path which now climbs gently along the right bank. There are several spots by the water ideal for a picnic or a dip... Follow the stream upstream along the water’s edge. After passing Les Petites Gillardes (often dry, especially in summer), continue along the path for as long as possible until you reach the D217 road. Follow this road to the right, cross the bridge over the Souloise and return to the car park (S/E).
