In Lannemezan, head towards Labarthe-de-Neste and follow the D929 to Arreau. On leaving Arreau, head towards Col de Peyresourde and Bagnères-de-Luchon. Leave this road at Avajan and turn right onto the D25 towards Loudenvielle. Then follow the signs for Pont de Prat, the end of the road where there is a small car park.
(S/E) Cross a small bridge and take a stony path to the right of the power station. Go through a metal barrier and follow a marked path on the right. You will reach the junction with the Pez valley.
(1) Head towards the Soula refuge and the lakes on the left. This well-marked trail crosses two footbridges and then winds its way uphill. Along the way, information boards provide details about the local flora and fauna.
This path ends with a few steps and a pretty view of Lake Génos. You will arrive at La Santette.
(2) Enter the Clarabide Gorges. The path carved into the rock follows a contour line for about 2 km, then descends slightly to the small Soula bridge.
(3) Follow the pretty paved path to the Refuge de la Soula.
(4) From there, you can go to Lac de Caillauas by taking the path on the left or to Lac de Pouchergues by following the path between the buildings.
The view opposite the refuge is magnificent, with herds of izards often visible on the slopes of the Pales des Courtalets.
Return via the same route to the Pont de Prat car park (S/E).
