Pic de Vallhiberna

Tuca de Vallibierna is a summit in the Aragonese Pyrenees with two distinct peaks connected by a sharp ridge called Paso del Caballo. The higher peak reaches 3067 meters, and its white rock formations are visible from a distance below.

The first documented ascent took place in 1865 when Charles Packe reached the summit with guides Firmin Barrau and Charles. Later, Roger de Monts became the first to climb it under snow conditions during the winter of 1900.

Local communities in the Castanesa valley call this peak Piedras Blancas, a name inspired by its white rocks that stand out against the surrounding iron-toned mountains. This alternative name reflects how the landscape shapes the way people here think about the place.

The climb typically starts from Pla de Senarta, located about 6.6 kilometers above Benasque, where a campground provides lodging options. A bus stop nearby makes it easier to reach the trailhead from the town below.

The western peak, called Culebras, takes its name from snake-like patterns visible on its northern face. These natural lines in the rock formation create a memorable visual detail that gave the peak its distinctive name.
