Access to the starting point: To the south of Pau, there is the village of Laruns where we follow the D-934 road. Three km after Eaux-Chaudes, take the unpaved track to the right that leads, after 1500 m, to the car park (940 m) near the Gorges de Bitet.
* Walk uphill through the forest and, after admiring the waterfalls, reach the splendid Lac d'Isabe (1.937 m, photo above). Take the direction of the steep grass slopes between the summit and the narrow gap to the right where you don't have to go. The sight of an antenna at the top (2.606 m) will surprise you. Easy descent to Col de Sesques and, from there, more complicated on the steep slopes. The narrow path veers right towards the impressive rock needle of Capéran de Sesques (photo below) and leads downhill to the cabanes de Cujala de Sesques and the starting point.
