Caves and potholes in Aiguafreda

Aiguafreda, in Vallès Oriental, occupies the narrow valley that the river Congost opens up between the foothills of Montseny and the Serra de Bertí, on the way to Osona. This natural passage, historically a route of communication, preserves rugged relief with limestone formations on its slopes, where the municipality’s catalogue of cavities finds its geological context.
