In the village of Les Ayes, park at the Chapelle Sainte-Élizabeth.
(S/E) Walk up through the village. After the last house, take a wooden bridge on the right to join the GR® (red and white markings). Follow the GR® markings up into the Torrent des Ayes valley.
(1) Pass the first forest track.
Still following the GR® markings, join a track suitable for 4x4 vehicles.
Cross the bridge.
(2) Follow the path up the right bank of the torrent (Orange Saumon markings). When this joins the GR®, continue in the valley alongside the torrent.
(3) Cross a track that leads to a sheepfold on the other bank. Continue along the bottom of the thalweg. Through fields, climb parallel to the torrent (still on the right bank) and join the GR® track at the chalets.
(4) The track ends.(At this point, take the time to spot the Col de la Taure (6) on the right at a right angle, which will be our destination later on).
Follow the GR® signs to the pass.
(5) Col des Ayes. Beautiful view of Mont Viso. U-turn: retrace your steps and go straight down to the bottom of the thalweg, avoiding the scree, until you reach the crest of a moraine. Follow the moraine to its large terminal scree slope.
Don't go into the moraine, but turn left at a right angle to cut across a small scree and join a horizontal path on the flank. Follow the higher path, staying level and avoiding the scree as much as possible. After about 30 minutes, you reach the path leading up to the Col de la Taure (2423 m), which you found earlier (don't be tempted by the false pass on the left). Very faint salmon markings. Climb to the Col de la Taure.
(6) Once over the Col de la Taure, follow the path signposted Saumon: first to the right at level level, then downhill across the meadow, then finally at the bottom of the thalweg and down to the Chalets de la Taure (wooden fountain and drinking trough).
(7) Turn left again at a right angle on an unmarked path that follows the contour line. Beautiful views of the lake and Pic Peyre Eyraute opposite. The path joins a 4x4 track which you follow downhill to the right and which splits in two at the next crossroads.
(8) Take the track on the right towards the lake.
(9) Take the path parallel to the track towards Lac de l'Orceyrette. Go around the lake to the right. Swimming is possible (cold water). Reach the dyke used as a dam.
(10) Do not take the footbridge, but walk down the right bank along the Torrent de l'Orceyrette. Reach the large flat area at Plan Peyron.
(11) Plan Peyron. Join a track that rises to the right; follow it for about 200 m.
(12) A little-used path runs parallel to the torrent on the left. Follow this path back to the starting point (S/E).
