This route is an easier alternative route to n°3 (Les Roseires).
To start this trail take a car or the free shuttle bus from Les Diablerets to Col du Pillon.
The route starts at the entrance of the snow covered road that leads to Lac Retaud and Isenau. The road is in the forest (it is also a road for pedestrians.)
Around 300 metres before arriving at Lac Retaud, in the last turn, fork to the left across the hills and the forests, then head towards the area called “Fenil Durand”
You can then go back up the road, which goes along the Route du Pillon around the hills in the direction of Col du Pillon.
This route can be done in both directions.
