Park near the Riondet Lodge.
(S/E) Start heading east along the path leading to Pré Pollet. The route is flat at first, even slightly downhill, then climbs gradually before becoming much steeper as you approach the cliff section. Enjoy the view over the valley. Reach the junction leading to Pré Pollet.
(1) Turn left onto a blue-marked path which continues the climb, zigzagging towards the ridge. The path climbs towards the edge of the cliff then disappears into a small basin (rocky depression).
(2) Go round it on the right before reaching the edge of the cliff again. Follow the edge of the cliff to the summit of Mont Beauvoir, marked by a triangulation point.
(3) Continue along the cliff to rejoin a good path that runs alongside it.
Just before reaching the Col du Caut, slightly to the left, the path disappears again (the Col du Caut path is then a forest track that you cannot miss). Reach the pass.
(4) Join the excellent Col du Caut path, which allows you to descend comfortably and quickly down the cliff to reach the Mont Grelle forest road.
(5) Take it to the left towards the south. Reach the summit of the Prés du Riondet, then, via a short stretch of tarmac road, the car park at the start of the hike (S/E).
