Description

This route is accessible to all and offers some beautiful panoramic views of the Pic du Morgon, Dormillouse and Lake Serre-Ponçon. The little sister of the "Les Glaisolles" route, this shorter walk offers a similar atmosphere. On the menu: scrubland, black marl, views of the lake and surrounding peaks. A lovely walk on which you can enjoy the peace and beauty of Lake Serre-Ponçon. 1) Head down the road towards Les Hyvans. At the hairpin bend, level with the tennis courts, take the path on the right and quickly turn right onto a stony path that rises quickly. 2) Continue on this path for 2 km before turning right at the Col Lebraut. 3) Descend on this path until you reach the road, then turn right. Continue along this stretch of road back to your starting point.
