High Pyrenean Route Ossau Valley

Ossau high route: four days linking Midi d’Ossau, Palas and Balaitús

Link Midi d’Ossau, Palas and Balaitús with PirineoSur on a four-day high route. This outing combines hut-to-hut travel and summit ascents, starting at Portalet and finishing the walking route at La Sarra.

This high route links three summits and several huts between the Ossau and Tena valleys. Preparation combines the effort of consecutive days with technical rock and snow passages, making both important before travelling. Describe experience with scrambling, ropes and crampons to agree on the route and equipment with the guide. Arranging the final transfer from La Sarra to Portalet completes the traverse’s logistics.

• Season: mid-June to late September.
• Location: Ossau and Tena valleys.
• Duration: four days.
• Group: one to four people.
• General level: medium-high.
