The walk starts at the end of the Route Forestière des Essarts, 2 km above the forest chalet at the foot of La Combe.
(S/E) Head south-west along a well-marked path which, after a 15-minute walk, will take you to the Lescherette alpine chalets.
(1) When you reach the last chalet, carry on by crossing the stream. The path climbs steeply to reach a first plateau, where the Valette and Pierre valleys meet.
(2) Continue left towards the Valette valley until you reach the Valette chalets, then carry on to the stream.
(3) Then, on the right bank of the torrent, take a path that climbs up an old moraine to reach a second plateau, where you will find the Gollachon hut on your right.
(4) From there, follow the torrent – now a stream – upstream to the spillway of Lac de la Valette.
(5) After a well-deserved break, head back along the same route to the end of the Route Forestière des Essarts (S/E).
