Stop at the first car park on your right (just after the Tech dam).
(S/E) Head due west. Follow this path which climbs steadily. Leave the forest.
(1) You’ll arrive above a water intake built on the stream. Continue to the right, staying on the left bank of the Labas stream, along a very well-marked path. Pass a small ledge and reach a fork
(2). The Bouleste hut is 50 m to the left. Turn right onto a path that climbs and heads due north into the mountain pasture (left bank of another stream).
Cross this stream and follow a well-marked path heading south-west. Cross another stream, head north-west and reach the Col d’Uzious (2,236 m).
(3) From the pass, you can climb to Pic Sanctus by following a path that climbs gently north-eastwards. Go round the first peak you come to. Then some yellow markings will help you follow this steep path to the summit (2482 m) of Pic Sanctus. Follow the few remaining yellow markings carefully. Do not attempt this route in poor visibility (fog, rain).
(4) Descend back to the Col d’Uzious, turn right to descend to Lac du Lavedan (2,179 m) and Lac d’Uzious (2,115 m).
(5) Return via the same route.
(1) Take an alternative route at the water intake. Turn right, pass the EDF building by crossing the stream and follow the yellow markings. The return route then follows the right bank of the stream.
(6) At the fork, head down to the left into the forest. Leave the forest to arrive at a large clearing.
(7) Head straight on, ignoring the marked path that branches off to the right towards Lac de Pouey-Laun, and join the D105.
(8) Turn left; it is a further 300 m to the cars (S/E).
