Caves and potholes in Sant Cugat del Vallès

Sant Cugat del Vallès, in the Vallès Occidental, sits on the northern slopes of the serra de Collserola, with the Benedictine monastery of Sant Cugat, of medieval origin, as the historic core of the town. Despite the strong urban growth of recent decades, the territory retains wooded and rugged sectors in Collserola, where some cavities typical of this massif have been catalogued.
