At Premier Villard on the Route du Col du Glandon, head up to the right to take the Bois du Nant forest track. Once on the track, at the first bend, continue straight on to the Pont des Reisses, where there are a few parking spaces.
(S/E) Shortly after the Pont des Reisses, you will find a wooden sign. Turn left and follow the path towards the Chalets du Bacheux. Continue along the left bank of the Torrent du Bacheux until you reach the Chalets des Barnes.
(1) Continue along the left bank of the stream until you reach the Collet valley. Here, leave the stream before returning to it and reaching a fork in the path.
Follow the yellow markings to reach the Chalets du Bacheux, ignoring the path on the left which descends towards Les Granges and the Route Forestière du Stream du Bois du Nant.
(2) Continue left to reach the stream. Cross it and follow its right bank, then cross again. Leave the left bank of the stream and take the path on the right, continuing the ascent to reach the plateau of the Bacheux lakes.
(3) Return via the same route to the Pont des Reisses car park (S/E).
