To get to the car park at the start of the walk, head towards Onoz, which is on the D 360 leading to the Vouglans Dam. Before leaving the village in the direction of Cernon, take the local road on the left towards the hamlet of Chavia. After 1.1 km, turn left onto a gravel road at the sign for "Belvédère les Bourlaches". The car park is 100 m along on the left-hand side of the road.
(S/E) Leave the car park and take the white path heading east. You are now on theGRP® Tour du Lac de Vouglans and should follow the red and yellow markings. After about 120 m, take the path on the left heading north. Continue in this direction until you reach a clearing in the forest.
(1) Turn right towards the north-east to reach the Belvédère des Bourlaches viewpoint.
(2) After admiring the landscape and the superb views of the lake, leave the viewpoint to continue on theGR® and begin the descent towards the lake, following the red and yellow markings. After 3 km of winding descent through the forest, you will come to a T-junction with a path slightly overlooking the lake.
(3) At this point, continue to follow theGRP® trail and take the path on the left that runs along the steep bank and gives the impression of a lunar landscape. Continue walking with the lake on your right for about 1.6 km. Feel free to take one of the few small paths that lead to the lake, as this is an opportunity to take a short break on a small wild beach.
(4) At the enclave of the commune of Orgelet, leave theGRP® and turn left onto the path leading up through the woods. Stay on the main path until you reach the edge of the woods and the Maison Forestière des Louvetières heading south.
(5) 150 m after Les Louvetières, turn left towards the south-east. Continue for 1.2 km along the edge of the woods and meadows until you reach the Bourlaches car park (S/E).
