Start from the car park at the church in Saint Alban-des-Villards.
(S/E) After passing through the hamlet of Le Mollard, the tarmac road turns into a track which you should follow without crossing the Torrent du Merlet. After about ten minutes, you’ll reach the Croix des Charrières.
(1) The track, and then the footpath, will gradually wind its way through the Vallon du Merlet, passing through clearings and then through woodland, until you reach L’Échaut.
(2) Pass through this hamlet, cross the torrent and turn left. Then continue along a track towards Les Granges
(3) Leave the Col des Balmettes path on your left and continue into the valley. The ascent is gradual through alpine pastures
(4) Once you reach Plan des Sources, carry on straight ahead towards the Col du Merlet along a path that becomes steeper.
(5) After a well-deserved break at the pass to take in the views, head back along the same route to the car park at the church in Saint-Alban-des-Villards (S/E).
