Caves and potholes in les Planes d'Hostoles

Les Planes d’Hostoles, in the Garrotxa, sits in the valley of the Brugent river, in a territory that forms a transition between the comarca’s volcanic zone and the buttresses that rise towards the Guilleries. This geological diversity, with limestone materials interspersed with more recent formations, gives rise here to a cave catalogue typical of this sector of the Garrotxa.
