Coming from Les Esterets du Lac, head towards the Fustiere D37 bridge to reach the lake (car park).
(S/E) From the car park, leave the road and take the path to the north-east, leaving the Vallon des Vaux on your right.
(1) At the dam on the right, turn left and follow the GR®49. Pass through the Saint-Cassien National Forest (a few paths on the right lead to the lake). Stay on the main marked path, ignoring all the side paths.
(2) At a fork, keep to the right. Continue to follow the GR® trail, staying close to the lake. Pass La Verrerie on your right. You will arrive at an intersection with the water sports centre opposite.
(3) Leave the path on the left and continue opposite the bay. Continue along a cove of the lake.
(4) Move away from the lake by climbing to the left for about 500 metres.
(5) Leave the GR® and take a PR® on the left at Gayet. Climb up a wooded path. Continue to a cistern.
(6) Leave the PR® and turn left onto an unmarked path. Cross the forest towards the lake, south-east, for about 1 km.
(2) Return to the GR®49 and follow it to the right until you reach the car park on the D37 (S/E).
