Park your vehicles in the car park at the entrance to the Rosier campsite (S/E).
Turn left and cross the road opposite the Rosier fountain.
(1) Take the Promenade et Randonnée trail (PR® yellow markings) indicated by the sign to the left of the fountain.
Climb gently through the meadows and then into the forest overlooking the right bank of the Clarée.
Join a wide forest track, cross the Rivet torrent before descending slightly to the Serre district of Val des Prés.
(2) Undertake a short climb then a descent to reach the Granon chalet road.
(3) Take it on the left, turn right at the next crossroads and continue on this track until you reach the footbridge that crosses the Clarée.
(4) Then tackle the steep climb (still following the yellow markings and signs), cross the D994g road and finish the ascent at the cave.
(5) Begin the descent on the left bank of the stream, reach a large meadow and then start another climb in the woods (markings and sign, see Note in the Practical Information section) to rejoin a track. Descend to the right to reach the junction of the direct path to Val des Prés.
(6) Take this path, which starts on the left (signposted Val des Prés 40').
Continue along this path until you reach the edge of the road, but stay on the path on the left.
Reach the Draye bridge at the entrance to Val des Prés.
(7) Before the bridge, take the path that runs alongside the Clarée river and leads to Le Rosier and the car park (S/E).
