Arrieu (cours d'eau) - Affluent de la Neste walks

Third stage of the Ténarèze. From Ancizan, follow the GR® 105 north-east, crossing summer pastures and beech woods with views of the Pic du Midi de Bigorre. After Cadéac, the trail leads to Arreau, the former capital of the Aure Valley. Then take the old railway line (now disused), a flat path lined with ferns, to Fréchet-Aure. This balcony village, listed as one of the "Most Beautiful Villages in France", offers a panorama of the Pyrenees and a preserved pastoral heritage.

The second stage of the Ténarèze, at the bottom of the Aure valley, runs alongside the Neste river through fields. In places, the path widens, suggesting the trace of the old drovers' road, particularly near the Nourde footbridge. A peaceful route that passes through several small rural villages set on a plain ideal for resting herds before the climb to the summer pastures.

Ascent to the Hourquette de Caderolles, the Col de Bastanet and overnight stay at the Campana de Cloutou refuge. This first stage is classified as difficult because there is a lot of elevation gain.

This second stage, after spending the night at the Refuge de Campana de Cloutou, returns to Artigues, off the beaten track, with the discovery of the little-known Montarrouye valley.This day is classified as difficult because you need to know how to find your way.

Second stage of the Three Days in the Néouvielle Reserve and its lakes. From the Bastan refuge to the Chalet-Hôtel d'Orédon. The tour and contemplation of the 20 lakes continues. You are entering the Néouvielle National Nature Reserve, which is protected by regulations. Please respect these regulations (see practical information).
