Antras walks

The route is mainly in the shade. Only the summit is in full sun from the village of Antras. The climb up the Col de Mourères is not difficult. A beautiful walk on the Balcon du Biros

A circular loop to climb Pic de l'Arraing via Pic de Sérau, following the pretty ridges.

Two days, exploring both sides of the cool Biros Valley through which the River Lez flows, in a very mountainous setting.One night’s stay in the hamlet of Eylie d’en Haut. The mountain refuge and dining area are separate and welcoming.Both days are spent largely on marked trails, but these are challenging, sometimes steep and often very steep.- The first day is challenging, with 1,200 metres of ascent and 900 metres of descent. Do not underestimate it. The descent from the Col des Cos is not straightforward due to the patous and the path being difficult to follow, despite the markings, as well as the crossing of the Ruisseau du Haurendech (torrent). The views make you forget these difficulties.- The second day begins with a very steep climb (25 per cent gradient). Then, the beautiful balcony path requires great caution as it is not maintained and is very narrow. After the Col des Cassaings, conditions improve. The views make you forget these difficulties.

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.

First stage of the Petit Tour du Biros.From the Anglade car park, a steady climb along theGRP®® Tour du Biros to the Passerelle des Pichès, then a detour via the Chapel and the Cabane Forestière de l'Isard.Then, after returning to theGRP®®, you arrive at the Cabane d'Illau.This is followed by a steep climb up to just below the Étang d’Araing dam and finally the arrival at the Refuge Jacques Husson de l’Étang d’Araing.This stage is only feasible when there is no snow, from late May until the huts close or the first snowfall begins.

Suggestion for a shorter Tour du Biros with alternative routes.Start from the Anglade car park (Frechendech).A fairly challenging first stage with an alternative route via La Chapelle and the Maison Forestière de l'Isard.A second stage exploring an old lead and zinc mine, preceded by the ascent of the Pic de l’Har.A third, more leisurely stage, but over rough terrain, on a path damaged by fallen trees and the absence of a footbridge over a torrent.This route is only feasible when there is no snow, from late May until the mountain huts close or the first snowfall begins.

This large circular takes us through varied landscapes, discovering the riches of the Couserans. The Pic de Crabère is the remarkable highlight of this beautiful journey. From its height of 2,630 metres, you can see the high peaks of the Ariège and Luchonnais on either side, while to the south, the Aneto massif dominates the landscape. To fully enjoy this long hike, don't hesitate to stop for the night at the Étang d'Araing refuge. You'll have a front-row seat to watch the magical spectacle of the sunset over the Pic de Crabère.

Torrential streams, forests, mountain pastures, panoramic views, huts and chapels await you on this hike at the bottom of the Biros valley.

A beautiful ridge walk offering magnificent views of the Pyrenean mountains, including Mont Valier and the Piedmont. Moderately challenging, it is fairly easy to complete. It is possible to stay overnight at the Cabane de l'Arraing: maximum four to five places.

Splendid view of the Couserans peaks with a crossing of a summer pasture and the discovery of an old marble quarry.

Summit with a superb view of the Couserans part of the Pyrenees mountain range.

A magnificent viewpoint over the high peaks of the Couseran. An easily accessible summit, passing by the old Bentaillou Mines and the Étang d’Araing. Please note: the return route via the Col de Clos requires a basic knowledge of navigation (especially in bad weather).

Combine mountain hiking with discovering industrial heritage.This valley has a significant mining heritage, and the succession of reminders of this during the climb, dotted with ruins and twisted, rusty scrap metal, evokes the past importance of the heart of our mountain range.

Third and final stage of the short Tour du Biros.The return route follows a very interesting and well-marked path, passing through Col des Cos.A lovely hut with a new roof, open to the public, is available at this pass as a new hut has been refurbished for the shepherd(s). There is also a water source at this spot.A very beautiful descent until you reach the GRP® Tour du Biros.Pass by the lovely Passerelle des Pichès footbridge.You pass through the hamlets of La Peyre and Frechendech before arriving at the car park.This stage is only possible when there is no snow, from late May until the mountain huts close or the first snowfall begins.

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).

The highest point in the Val d'Aran and Couserans, Maubermé is often overlooked in favour of Mont Valier. However, unlike Valier, the path climbs steadily and pleasantly to Port d'Urets (and its small hut where you can spend the night), then becomes a little steeper to reach the summit, which may prove a little difficult for those who are not used to it.

A beautiful outing between Ariège and Haute-Garonne, tackling the Col de Portet d'Aspet

An unusual hike along an old mining railway line with tunnel crossings.

A steep climb rewarded by a 360° panorama of the Couserans and Biros peaks.
