An alternative to climbing Mont Valier, passing through the adjacent valley and the Col de Pécouch, offering a change of scenery and magnificent landscapes.

From the Maison du Valier to the Col de la Core – update to the GR®10 route

Very difficult
Departure from Les Bordes-sur-Lez (Ariège)
Since the fire in July 2026, the terrain has been very unstable (frequent rockfalls) on the GR®10 towards the Ayes Lake, and this section of the path is therefore closed. Consequently, the ONF recommends an alternative route, the details of which are given below, between the Maison du Valier and the Col de la Core. The start and finish points of this stage are accessible by car.

Departure from Sentein (Ariège)
Second day of this trip to the Refuge d’Eylie. A day not to be underestimated.Classified as difficult due to an average gradient (slope) of 24% from (1) to (3). Afterwards, the GR®10 access trail – GRP® Tour du Biros – is very narrow, poorly maintained and at times dangerous due to low-lying, slippery rhododendrons: it is a north-facing slope. There are moments of respite in the woods, where the path is fairly wide and very well signposted. From the Col des Cassaings onwards, conditions improve. The highlights of this balcony trail are the numerous viewpoints from (3) to (4) and from (4) to (6).After at least 6 hours’ walking, including breaks, with 900 m ascent and 1,150 m descent, the arrival at the Ostal du Biros in Bonac is a welcome relief. From there, it’s a 25-minute drive along a very quiet road back to Sentein (E).

Departure from Sentein (Ariège)
First day of this trip to the Refuge d’Eylie. A day not to be underestimated.Set off from Sentein along an old track, then take the small road up to Bencarrech, joining the GRP® Tour du Biros. The GRP® in the Isard Valley crosses to the other bank via the Illa Maria footbridge. It then passes the Passerelle du Pichès on the right and begins a steep climb. From there, a PR® trail leads to the Col des Cos (mountain hut, fountain). This is followed by a tricky descent due to fallen trees blocking the path (PR®). After at least 6 hours’ walking, including breaks, with 1,200 m of ascent and 900 m of descent, the Eylie restaurant and bar is a welcome sight.
