Corrections after the route on 01/11/202...
Park just after the orientation table and the Bedous geological area. You can continue a little further up the tarmac road, but it would be a shame not to take advantage of this exceptional point of interest! Please note: do not obstruct the road, as agricultural machinery sometimes passes by. Otherwise, park in the previous hairpin bend.
(S/E) The yellow-marked path starts at the end of the tarmac road, slightly to the right, signposted towards the Ourdinse hut. It starts as a sunken, shaded path that climbs quite steeply before veering slightly to the left (north) at the edge of a meadow and joining a signposted fork.
(1) Take the right fork. The path climbs steadily along the upper edge of the forest.
(2) At one point, the path passes through the undergrowth and leads to the "Font Larrun" spring, whose water quality is not guaranteed. At this point, take the left-hand path uphill and ignore the right-hand path which leads to Aydius (Chemin des Ardoisières). The path leaves the forest and reaches another fork. Turn left again and climb the winding slope before heading north-west.
You will then have to climb the entire grassy slope in a more or less zigzag pattern, but the path remains very well marked. Come out onto a ridge, then cross another grassy slope (see photos).
(3) At the first trees, the slope levels out and you just have to follow a small "suspended" valley and turn right at the end of it, sheltered by a few beech trees. Cross a small, rockier section and you will come out onto a pasture that is half rock, half grass, where the trail markers are less obvious; the Ourdinse hut is visible below on the right.
(4) You will see a ruined circular stone building with two wooden posts in the middle. Take the path that climbs slightly behind it.
(5) After about 150 metres, you will reach a path leading from the Ourdinse hut to the Casteruch hut.
Off the beaten track: it is very easy to climb the Pic des Taulères (about 15 minutes, 1,571 metres), which offers a sweeping panorama.
Climb a few more metres and you will reach the end of the ascent. Continue along the same path, which gradually turns and heads west. After a slight descent and a series of hairpin bends, the path heads straight for the Castéruch hut. Continue down the ridge, without veering towards the grassy slope on the left.
(6) When the ridge reaches a flatter area, at a fence, the path suddenly turns south and crosses the slope before winding downhill and rejoining the ascent route.
(1) All that remains is to follow the path you took on the way up, first through a meadow and then along a sunken path to return to the starting point (S/E).
