(S/E) Park in the Pont d'Espagne pay car park, then follow the tarmac road for about 400 m to reach the signpost.
(1) Before reaching Pont d'Espagne, turn left onto theGR®10, which climbs through the forest following the Gave de Gaube. At the edge of the forest, you will come to Lac de Gaube.
(2) Continue on theGR® trail, skirting the lake along the western shore. The trail crosses scree and begins to climb again after the lake. The magnificent trail climbs in stages (however, the slope is never too steep). Cross the Gave des Oulettes de Gaube twice and you will arrive (about 3 km after the lake) at the Petites Oulettes wetland just after the Darré Splumouse waterfall.
(3) At the huge cairn marking the entrance to this wetland, leave theGR® and take the path on the right that leads to Lac du Chabarrou. At first, the path is not very visible, but it quickly becomes well marked on the ground and dotted with numerous small cairns. The climb is short but steep, leading to a small lake and a beautiful waterfall before arriving at Lac du Chabarrou.
(4) Enjoy the lake before heading back down the same route to (S/E).
