Coming from Les Esterets du Lac, head towards the Fustiere bridge on the D37 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 the four-way fork, keep right, continue straight ahead and follow the GR® a short distance from the lake. Leave 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 until you reach a fork.
(5) Leave the GR® and take the PR® on the left at Gayet. Climb up a wooded path. Pass under the high-voltage line and reach the next fork (elevation 301).
(6) Leave the PR® and turn left onto the 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).
