The HRP, or more precisely the “Haute Route Pyrénéenne”, is a long-distance hiking route which, in 45 high mountain stages, crosses the Pyrenees, linking the Atlantic to the Mediterranean. The crossing of the high valley of Ossau requires two stages, from the Col des Moines to the Refuge de Pombie and the Refuge de Pombie to the Refuge d’Arrémoulit.

There are three high mountain refuges in the Ossau Valley. From west to east, Ayous, Pombie and Arrémoulit are open in high season between late May and early October. They are located at an altitude of 2000m, and offer accommodation and food in an end-of-the-world atmosphere.
