La Charnay - Chalet d'Arvière

(S) From the hamlet of La Charnay, join the GR® forest track marked in red and white and continue straight on towards Le Tumet. It’s a pleasant warm-up walk through a large valley, with lovely unobstructed views of the surrounding area.

(1) At Le Tumet, the route leaves the forest track and climbs gently to the right of the house. The path enters the forest at the end of the valley, following a gently undulating route without any particular difficulty, until it reaches the Crêt du Nû junction. A short round trip takes you to the highest point of the Retord plateau (1,351 m) where you can admire the view.

(2) Begin the descent along the GR® towards Les Bergonnes. On leaving the forest, a forest track crosses the valley: take this track. Two water reservoirs follow one after the other on the left before the path plunges into the gorge and reaches the junction at La Croix de Terments.

(3) Go round the cross to the left and head down this charming valley. 320 metres further on, the GR® climbs to the left. Follow it and take the path on the same side. Pass under the high-voltage power line and join the white track that runs alongside it to the Planvanel farm.

(4) Continue along the forest track that branches off to the right, follow the edge of the forest, cross the fir forest and reach the Vézéronce stream.

(5) Cross the river and follow the dirt track to the right as far as the hamlet of Golet Grand Voie. The track continues to the left, leaves the forest track at the entrance to the valley and crosses a field in its entirety. It joins a dirt track at the edge of the woods, which continues to the left for 1.2 km to the Col de Richemond road.

(6) Turn left onto the road for barely 100 m, then rejoin the white path on the other side. The route enters the Combe à la Done, with a first house visible on the right before the entrance, then another higher up at the exit. Follow the path to its end.

(7) Cross the Tumelay stream on the GR® and switch to the left bank. The path climbs and overlooks the stream along a wide, wooded track, gradually over 2.5 km, before reaching a clearing and then the Combe Merlin. Continue to the junction with the Route Forestière de la Lovivre.

(8) Continue straight on along this semi-tarmac road to the Refuge de la Grange d’en Haut.

(9) Turn left. At the Col de la Biche road, turn left onto this road which descends slightly and, 250 metres further on, follow the path branching off to the right into the Combe du Cimetière to the ruins of the Grange d’en Bas.

(10) The GR® follows the ridge line and joins a forest track to the Grange de Falavier junction.

(11) Continue straight on along the white track, which descends towards the end point of this stage, the Chalet d’Arvière (E).

Before you set off
- Check the weather forecast to ensure there is no rain.

During the Second World War, the Retord was a key centre of the Resistance. The Maquis Trail and the Grange du Fort bear witness to this commitment.
