Take the D902 road along the Arc river to the old village of Bonneval-sur-Arc and enter at the Vieux Pont.
Park in the car park at the Old Bridge with two arches spanning a pond.
(S/E) Head towards the village in a north-easterly direction and, just before the Notre-Dame-des-Grâces chapel, take the street on the left. Cross another street and continue, passing in front of the La Torna chalet (on the left).
(1) At the village exit, turn left onto Chemin des Chèvres - AccèsGR® 5" (sign engraved on a wooden sign).
Note: From here, you can't go wrong if you follow the order: Les Roches, then La Lenta, then Bonneval-sur-Arc. But it costs nothing to give more details, so that's what I'll do.
The trail runs alongside the Col de l'Iseran road, below it. After 500 m, theGR® climbs to the right to join the road: it is better to stay on the trail for another 200 m and join the road further on to avoid a section on tarmac.
Walk down the road for a few metres to find the path that climbs up to cut across the next bend.
(2) When you rejoin the road after this bend, you are at a place called "La Cara" (yellow hiking sign). You are now facing two paths: a track that heads further to the left towards the south-west, and a path that climbs steeply towards the west. Take the second path, towards "Les Roches - Le Vallon".
This path, which is initially earthy and then becomes increasingly rocky, does not present any major difficulties, apart from the fact that it is often very steep. At the same time, you quickly gain height and superb landscapes are revealed as you go, particularly over the Haute Maurienne valley.
(3) You will arrive at a place called "Les Roches - 2440 m" (yellow signpost); head north towards "La Lenta" (GR® 5).
After crossing several streams on footbridges in excellent condition, you will find yourself on a balcony path with a view of a plateau area, Les Erès.
(4) Head for the yellow signpost that can be seen from afar, at a place called "Les Druges - 2260 m". Take the direction "La Lenta" (stillGR® 5).
From there, the descent is gentle, with views of the vast Lenta valley below and, upstream, the gorge that leads to the Col de l'Iseran and the mountain pass road.
(5) The track crosses the Lenta stream. Here you will find a series of tourist information panels about the Vanoise National Park, the hay meadows and the Lenta, as well as a yellow signpost. Head towards Bonneval-sur-Arc.
Follow the Lenta along its left bank for a short distance before crossing it again via the road bridge. You will soon see the pretty Saint-Barthélémy Chapel below on the left, then the road, after a wide left-hand bend, overlooks the Lenta gorge.
(6) Take the path (GR®) on the left which descends towards the river and follows it inside the gorge. The river cascades between rocky blocks, dams and water intakes. Soon, you will be overlooking Bonneval and descending fairly steep switchbacks.
(7) You will come to a fork in the path at the footbridge that crosses the Lenta to reach the Sentier du Petit Bonheur (which leads to the village of L'Ecot). At the sign (elevation 1850), follow the direction "Vieux Village par Chemin des Chèvres".
Halfway along, this path crosses the road and leads us to the village to rejoin the outward route
(1). Walk down the street for about 20 metres, then, in front of the La Torna chalet, take the alley on the right and follow it until it crosses a main street in the old village.
(8) Leave Chalet Bella Alpina on your left and go to see the Church of Our Lady of the Assumption. Return a few metres and take the lane on the right which, after turning left, leads to Chalet Le Bénal.
(9) At the Le Bénal chalet, turn right and follow the street that leads to the Notre-Dame-des-Grâces Chapel.
Turn right and return to the car park where you started (S/E).
