From Bourg-d'Oisans, head towards Saint-Christophe-en-Oisans and, at a place called "Plan du Lac", a few hundred metres past the dam, park in the car park on the right just after the lodge.
(S/E) At the end of the car park, take the double footbridge crossing the Vénéon torrent and walk a few metres to the crossroads.
(1) At the signpost, turn left onto the path that runs alongside the stream towards Saint-Christophe-en-Oisans. The path climbs slightly above the valley.
(2) At the signpost, turn right towards the Lanchâtra valley. A sign advises caution, but the path is perfectly passable and in good condition. The path climbs steadily to the start of the valley. Cross the Moulin footbridge over the Pisse stream.
(3) Follow the path on the left, which climbs steadily and runs alongside the stream for the rest of the route.
(4) Cross the stream via the footbridge and officially enter the Écrins National Park. Remember to close the gate behind you. Continue towards the Selle sheepfold.
(5) Arrival at the Selle sheepfold. Cattle and dogs present during the summer grazing season.
Continue the climb. Reach the highest point of the hike above the rocky outcrop to admire the cirque at the foot of Pointe Swan.
(6) Highest point and viewpoint. Turn back and descend via the same route to the crossroads at the Moulin footbridge.
(3) Continue straight on to the hamlet of Lanchâtra (well worth a visit).
(7) Continue along the path past the hamlet to begin the descent towards the Vénéon valley.
(8) At the junction, turn right. The path reaches the bottom of the valley and passes in front of the spectacular Lanchâtra waterfall. Continue along the path to return to the original junction.
(1) Turn left towards the footbridge over the Vénéon and head for the car park (S/E) .
