Park in the car park at the Nistos-Cap Nestès resort. If the resort is open, you will need to pay the snowshoe fee of €5 (-10% for groups of 10 or more).
(S/E) Head west via the ticket office. Climb west then north-west and reach the Col de la Lit (1,651 m) after about 400 m.
(1) Follow the right-hand track north for 250 m until you reach the hairpin bend. Then turn left and follow the north-west ridge to Cap d'Ausour.
(2) Continue along the ridge for 700 m until you reach the track, which you will follow until the hairpin bend on the right at the "Forêt domaniale" sign.
(3) Leave the track and head north to the wire fence, which you will follow on the right down a very steep descent into the forest to the Col de Bas, which is open.
(4) At the pass, head north through the woods for 700 metres until you reach Mont Castéra.
(5) Turn north-west, following the ridge. Reach the summit of Glouppe Hup.
(6) Then descend to the pass. Climb Pic de Montaut via the very steep ridge or go around it on the left to approach it from the less steep western side. This route is preferable in snowy conditions and is used here for the descent.
(7) Descend via the less steep western face to the pass. Go around Glouppe Hup, staying at the same altitude, then rejoin the ascent route. Continue to the right and pass Mont Castéra again, then Col de Bas.
(3) If your legs are heavy, take the track on the right leading to Col de la Lit (choice of route), saving you the climb to Cap d'Ausour.
(1) Continue straight ahead to return to the car park (S/E).
