On leaving Gèdre, heading towards Gavarnie, turn left onto the Héas road. At the junction by the Gloriettes dam, turn left and park in the large car park by the dam.
(S/E) Take the path on the left, cross the dam and walk around the lake along its left bank. Continue until you reach the footbridge on the botanical trail.
(1) Do not cross, but continue straight on to reach the Pont d'Estaubé junction on almost level ground.
(2) Stay on the left-bank path and reach the mountain pasture a few steps further on.
(3) Continue straight ahead and then tackle a short climb to pass close to the Cabane de Labassa. Cross several streams before reaching the Labassa stream.
(4) You will then begin a series of tight hairpin bends through the mountain pasture, before reaching a stony area and the junction with the path leading to the Brèche de Turquerouye.
(5) Keep to the right on the path and complete the ascent of the Hourquette d’Alans via a series of hairpin bends.
(6) Take the same path down to the Estaubé mountain pasture.
(3) Turn slightly right to enjoy the grassy area and reach the Pont d'Estaubé. Then head to the crossroads.
(2) Follow the same route back to easily return to the car park (S/E).
