Reach the village of Villard-Reymond from the Col d'Ornon road via the D210. Park at the bottom of the village in a large car park.
(S/E) Walk up through the well-restored village and past the town hall. You will come to a crossroads.
(1) Leaving the road, continue straight ahead uphill along the "Route du Solude". It turns right towards the pass, ignore a path on the left and continue for about 200 m to reach the Col du Solude.
(2) Enjoy the view from the orientation table in the field on the left as you arrive at the car park. Go back up the path on the ridge and rejoin the road. Continue on the road to the right until you reach the hairpin bend on the left.
(3) At this bend, leave the large antenna on your left and continue along the ridge. Follow the Prégentil to reach the Col de Saint-Jean.
(4) Go up to the left. When you reach the first pine trees, find the path that winds upwards slightly to the right (there are several options). Reach the Prégentil viewpoint.
(5) Enjoy the 360-degree view. Be careful of the cliff edge. To return to the car park, take the same path you took on the way up (S/E).
