Park at the Buet station car park.
(S/E) Cross the road at the pedestrian crossing and take the path opposite towards the Bérard waterfall. Once at La Poya, turn left and then right to continue the circuit and reach the waterfall.
(1) Continue to follow the path that runs alongside the Eau de Bérard, towards the Refuge de la Pierre à Bérard. You will reach a fork at the footbridge that crosses the torrent.
(2) Follow the path to the left without crossing the stream; you will cross it 150 m further on to reach the left bank. You will arrive at the Refuge de la Pierre à Bérard.
(3) Turn right to the north-west, towards Col de Salenton. Follow the somewhat uneven path marked by yellow rectangles. You will reach a junction.
(4) Leave the Col de Salenton on your left, continue to the right (north) and follow the path around the Aiguille de Salenton. Higher up, the path slopes to the right and rises steeply to reach the Arête de Mortine.
(5) Continue along the path to the right, heading north-northeast, pass the Abri de Pictet and reach the summit of Mont Buet at an altitude of 3,098 metres.
(6) Follow the Arête du Buet (north) along a steep path with cables and an aerial passage. Pass the Col des Èves and reach the Col du Génévrier before arriving at the peak of the same name.
(7) Continue straight ahead (north-east), leaving the Refuge du Grenairon on your left: the path becomes difficult to see. Continue, making sure you keep heading north-east towards the Cheval Blanc.
(8) Turn right (east) and start a steep descent on a dirt trail equipped with cables.
(9) When you reach the Pointe des Corbeaux, turn left and descend towards the dinosaur tracks, first east, then north. You will reach the site of the tracks.
(10) Continue on the trail, which follows the contour line.
(11) Turn right towards the Col de la Terrasse, reach an intersection and turn right again to continue climbing above the Lac Vert below on your right. Reach the pass.
(12) Continue along the trail towards the Loriaz chalets, with a fairly steep and earthy descent just below the pass. Reach the Refuge de Loriaz, where several trails intersect.
(13) Continue south-east, passing close to the Croix de Loriaz, then turn right and follow a series of hairpin bends leading to a fork.
(14) Take the hairpin bend to the right, cross the stream de Loriaz bridge and continue the descent until you reach a radio mast.
(15) Head left, turn right at the intersection ahead and, after making an S-bend, rejoin the tarmac road at Route du Chanté d'en Haut.
(16) Turn right and continue downhill, follow the shortcut on the left and rejoin the road further down. Continue left, negotiate the right-hand bend and join the D1506 (Route du Col).
(17) Turn right and drive carefully up the departmental road to the station car park (S/E).
