Start from Ax-les-Thermes station.
(S/E) With your back to the station, follow the N2020 to the right with care, as far as Savignac-les-Ormeaux.
(1) At a sports shop, take a small road on the left. Then take thesecond road on the right, Rue du Pont. At the next junction, turn right.
(2) At the fork in the road, turn left and cross the Ariège. Continue along the Chemin de Pradatel, which passes under a power line and then, at a hairpin bend to the right, under the N20.
(3) You will then begin a steep, winding climb up the tarmac road. Pass under a power line and head up the Najar valley. You’ll reach the Granges de la Vallée de Savignac and, 200 metres further on, the end of the tarmac road.
(4) Continue westwards along a path marked in yellow, which climbs gently through the woodland, still following the course of the Najar. Head south-south-west to reach the Jasse des Esquers de dessous.
(5) Continue along the path and, 300 metres further on, pass the upper Jasse des Esquers. Keep following the yellow markings and stay on the left bank of the stream. Reach the Pont du Ressec (a lovely spot, ideal for a picnic).
(6) Carry on southwards following the yellow markings and you’ll soon reach the first hut. Further south, you’ll reach a second hut.
(7) The path continues, still well signposted. It climbs quite steeply to reach the plateau.
(8) Continue south-west to reach the Prat Redoun mountain refuge (E).
I couldn’t find the various water sources as indicated, but I’d brought what I needed; there’s no water at Prat Redoun either… the pipes must be frozen at this time of year.
