Ascent of D'Acher Castle (2,384m) from Oza Bridge
The Château D'Acher, in the Parc Naturel des Vallées Occidentales, is one of the must-see climbs in this part of the Pyrenees.
Peña Forca (2,391m) and Rincón de Alano (2,357m) from the Puente de Oza bridge.
The Peña Forca, together with the Rincón de Alano and the Lenito peaks, form an impressive cirque of towers and limestone walls that jut out to the west of the Selva de Oza, and which form the finishing touch to the elongated Sierra de los Alanos.
