Caves and potholes in la Torre de Cabdella

La Torre de Cabdella, in the Pallars Jussà, occupies much of the vall Fosca, one of the great high-mountain areas of the Pyrenees, known for its early-20th-century hydroelectric heritage. Its municipal area, made up of several settlements, climbs up to the peaks bordering the Aigüestortes national park, with high-altitude cavities typical of this Pyrenean limestone relief.
