Caves and potholes in Caldes de Montbui

Caldes de Montbui, in Vallès Oriental, owes its name and its fame to the thermal springs already exploited by the Romans, with waters emerging at over seventy degrees that still feed active spas. The town centre, of ancient origin, sits at the foot of the Serra de Sant Sadurní. This nearby relief, of a limestone character at specific points, gives rise to a cavity or two recorded in the catalogue.
