Park in the first car park on the right as you arrive, just past the dam on the right.
Head towards the dam (north).
(1) Cross the Tech dam.
Continue along the path heading due east. Pass a concrete hut in good condition on your left.
(2) At a right-hand bend, leave the track heading right and take a path (on the left) that leads into the forest (north-east). From there, cairns will help guide your way.
Continue along this steeply ascending path. At around 1379m, there is a right-hand bend and the path turns east. On leaving the forest, it heads due south to “overlook” the dam.
The path winds through the mountain pasture. It is more or less marked. Do not head back down towards the forest. Cairns will help you find your way.
(3) Reach the Cuyèou de Labet hut and continue roughly due south, continuing to climb. Cairns will help guide your way. Pass through an area of scree and boulders. Follow the cairns closely; they will help you.
You’ll reach a hilly mountain pasture and continue due south. Soon you’ll be able to make out the pass on your left.
(4). Reach the pass (2187m). The area is not particularly dangerous, but we are in high mountains.
Return via the same route to reach the car park at the dam (S/E).
