Caves and potholes in Castellolí

Castellolí, in the Anoia, is best known for the permanent motorcycle racing circuit located within its municipal boundary, near the coll d’Estenalles and the western foothills of the serra de Montserrat. The village, small and rural in character, is surrounded by farmland and Mediterranean woodland. This relief near Montserrat contains karst formations consistent with the conglomerate and limestone of the massif.
