Parking is available at the south-western end of the Font d'Urle station.
(S/E) Head south on the gravel path to elevation 1,472. The start of the hike follows the "Sentier du Karst" trail, marked with triangular posts slightly protruding from the ground with arrows indicating the direction of travel. Then, at each landmark, a 1-metre post bears a number in ascending order and a description of the location.
(1) Note the markers and follow them to the left to reach the "Glacière" at marker no. 1. You can enter the ice house and then continue eastwards above ground to discover two other caves. Return to marker no. 1 and follow the markings on the ground to the left towards the south to reach marker no. 2, "Le Chaos", then marker no. 3, "La Grotte".
Heading left, reach marker no. 4, "Les Ruines", at an altitude of 1,520 metres. Return west, still following the markers on the ground, and head towards the cliffs. Curving to the left, reach marker no. 5, "La Falaise". Continue along the edge of the cliffs at the edge of the fence and reach marker no. 6, "Les Crevasses".
(2) At elevation 1552, leave the themed trail to the left and follow the edge of the fence. The unmarked trail slants south-east towards Pas Pascaud, turns south, heads east again and then north-east to reach the Fontaine du Chien.
(3) Do not follow the fence going up into the meadow, but turn right (east) and pass under the rocks overlooking the Fontaine du Chien. Come out onto the ridge and continue along the edge of the cliff until you find the fence again. Pass the Scialet de Baume Noire and then the Pas du Follet, always staying close to the fence.
(4) Continue south-east, then leave the fence on your left and climb eastwards over mixed grass and gravel. Reach the ridge, find the fence again and turn right towards the south to reach the highest point of the Puy de la Gagère.
(5) Descend east, then head northeast among the junipers.
(6) Join theGR®93marked in red and white along the edge of the fence and follow it to the left, first on the eastern slope then on the western slope of the ridges, almost in a straight line to reach the Col du Pot de la Croix.
(7) Head left, slightly uphill, and cross the scree. Pass a grassy section and come to a fork.
(8) Leave theGR® trail and follow a faint trail in the grass to the right, heading north then north-west. You will arrive at a meadow.
(9) Turn right towards the east to visit the spectacular Scialets des Cloches (unsecured, caution advised).
(10) Retrace your steps back to the meadow.
(9) Continue south-west (do not take the path you took on the way there). At an altitude of 1,520 metres, join the red and white markedGR® trail and follow it to the left.
(8) Continue south-east on theGR® and return to the Pot de la Croix.
(7) Turn left at the hairpin bend and descend to the edge of the forest. The trail reaches a forest track coming from the right. Continue straight ahead, ignoring the other paths, and arrive at an elevation of 1334 metres at the Pelouse de la Croix.
(12) Continue to the right to reach the Col de la Chau. On the right, a path with steps leads to the Resistance Memorial.
(13) Retrace your steps back to the pass and then to Pelouse de la Croix.
(12) Go uphill to the right through a grassy gap.
(14) After 200 metres, follow the flat path to the left and after 50 metres on this path, you will see a cave below on the left. Retrace your steps along the grassy path.
(12) Turn left and follow the path west to a road (D76). Follow it for 150 metres to the crossroads.
(15) Turn left onto the road climbing south (D76b), which will naturally lead you back to the starting point at the end of the resort (S/E).
