Cerbillona, Mountain peak in Pyrenees, France and Spain

Cerbillona is a mountain peak in the Pyrenees reaching 3247 meters above sea level and forming part of the Vignemale massif along the border between France and Spain. The summit features rocky slopes and offers views across both countries for those who reach the top.

The summit sits on the Franco-Spanish border between boundary crosses no. 314 and no. 315, and it marks the watershed between the Adour basin, draining north to the Atlantic, and the Ebro basin, draining south to the Mediterranean. It forms the south-western upper rim of the Ossoue glacier together with the Pic Central (3,235 m) and the Clot de la Hount (3,289 m).

The summit sits on the Franco-Spanish border between boundary crosses no. 314 and no. 315, and its name appears in Aragonese as Punda de ro Cerbillonar alongside the French pic de Cerbillona and Spanish pico Cerbillona. It marks the watershed between the Adour basin, draining north to the Atlantic, and the Ebro basin, draining south to the Mediterranean.

The ascent is possible through several established routes, with the main path starting from the Refuge des Oulettes de Gaube on the French side. Climbers should bring proper gear and alpine experience, as the route involves steep sections and rocky terrain throughout.
