Departure from Barèges (Hautes-Pyrénées)
This three-day hike takes in at least 20 lakes.It is divided into three sections and includes two nights in a mountain refuge (or in a tent).The first day is still quite challenging, though.The durations of each stage are those I noted down. They include breaks for photos, meals, chats and dipping your feet in the water, and I’d like to remind you that these are three hikes (at a normal walking pace).
Please note: booking issues have been reported at various mountain huts on 10 August 2026. Furthermore, the Bastan mountain hut will be closed by the authorities from May 2025 until safety standards are met.
