The Notre-Dame de Liesse Chapel

From the parking lot Col de la Bigue, cross the road and take the path on the right from the fire water tank. Roam the path on the ridge until the intersection at 800m.
1 - Take the left path going into the woods, follow the ridge for about 1.5km to the Notre-Dame de Liesse fork with a peak at 996m. Turn right on the path going up to the chapel (round trip itinerary; remarkable view). From the chapel, come back to the crossroads and continue the path in the woods. Go down the Collet de Liesse.
2 - Don't take the left path going down to Verignon and continue straight on the ridge towards Saint-Priest. Reach the Chapel in about 3km. Go down the road for about 1.5km passing in front of a ruined barn on the left.
3 - Take the track starting on the right. It joins a path below at 900m (DFCI water tank).
4 - Follow the path on the right until the intersection at 500m. Turn right, stay on the main road for another 1.5km before reaching the intersection of the tracks of la Grave and le Brès.
5 - Follow the track on the right (la Grave) and go down the valley of the Grande Colle.
6 - Take the track rising on the right. Go up the valley for 2km. At the top, we can recognize the Notre-Dame de Liesse chapel. The path reaches a peak before a slight descent. Continue on the descending path towards the Col de la Bigue. A 800m before the pass, the trail reaches the point (1). Take a left to return to the starting point.
