Caves and potholes in Sant Feliu de Llobregat

Sant Feliu de Llobregat, in the Baix Llobregat, sits on the banks of the Llobregat river, at a point where the river plain meets the foothills of the serra de Collserola. Despite its strongly urban character, typical of the Barcelona metropolitan area, the territory retains rugged sectors towards Collserola, where the cave catalogue finds some formations.
