From the hostel, we follow the trail towards Paso del Caballo and continue on to Anzotiello. The route passes beneath impressive peaks such as Mallo Gorreta and Quimboa, which form a striking wall of rock above the valley.

Refugio de Gabardito – Salto la Vieja – Plandániz – Collado de Foratón – (Bisaurín) – Lizara

Time: 3–4 hours (6 hours with the ascent of Bisaurín) Distance: 9.6 km Elevation: +693 m / -536 m (plus +700 m with the ascent of Bisaurín)

This is the shortest stage of the trek, normally taking around four hours. For those looking for an extra challenge, we can add the ascent of Bisaurín. This detour adds about three hours but is well worth the effort. As the highest peak in the area, Bisaurín offers outstanding panoramic views across the Pyrenees.

This stage is renowned for its spectacular scenery, especially the Valle de los Sarrios (Valley of the Chamois) and the beautiful Ibón d'Estanés, a glacial mountain lake.

The day begins with a demanding two-hour ascent from Refugio de Lizara. Once we reach Paúl de Bernera, the trail becomes gentler, leading through the wide and scenic Valle de los Sarrios.

From here, we descend toward Ibón d'Estanés before continuing through an enchanting beech forest (Bosque de las Hayas) on the way to Somport. This varied stage is one of the highlights of the Senda de Camille trek.

This stage showcases the Pyrenees’ diverse landscapes, from the lush Sansanet forest to the scenic Espelunguère valley, ending at the beautiful Arlet Lake and mountain hut at 2,000 metres. Along the way, we pass traditional shepherd cabins, with the unique chance to purchase homemade local cheese directly from the shepherds.

Arlet – Col de La Cuarde – Col de Pau – Cabanne de Bonaris – Labrenère – Lescun

Time: 6 hours Distance: 19.5 km Elevation: +518 m / -1641 m

This stage follows the historic Chemin de la Liberté, once used by refugees fleeing persecution during wartime. It also traces part of the ancient Camino de Santiago route in Aragón. The day ends with breathtaking views of the Cirque de Lescun as we descend into the valley.

Lescun – Mazouza – Ansabère – Col de Petrechema – Foyas del Ingeniero – Linza

Crossing back into Spain, the trail traverses limestone terrain before descending through ancient beech forests toward Linza, bringing the circuit to a memorable close.
