Park in the car park at the exit of Les Cammazes (or in front of the Voûte Vauban tea room). If you want to be closer to the dam, you can try to park there, but there may not be any spaces available.
(S/E) Head east along Chemin de la Rigole and follow the stream.
(1) At the crossroads, continue straight ahead and you will reach the dam. Take the road on the dam.
(2) At the end of the dam, take the road on the right and go around the barrier. Make a hairpin turn to the right and follow the lake. Stay on the main road, as close to the lake as possible, and ignore all the turnings on the left.
(3) Cross the Sendou stream and make a hairpin turn to the right. Continue on the main road, staying as close to the lake as possible.
(4) Turn left onto the path that branches off from the lake. At the barrier, immediately take the path on the right at an acute angle with a slope. Pass the stone bridges.
(5) Cross the Sourette stream and ignore a path on the left immediately after.
(6) After about 200 metres, take a narrow path downhill on the right. At the bottom, turn left.
(7) Cross the Ruisseau du Dor and reach the lake. Continue straight ahead on the main path, on the south bank of the lake, ignoring all paths on the left.
(1) Follow the stream you followed on the way there to the left to return to the Cammazes car park (S/E).
