Provincial nature reserve
The shores of Lake Caldonazzo, the largest natural body of water entirely in Trentino, have been profoundly modified over time. The typical perilacunal vegetation survives only along some stretches of the shoreline: the two largest strips, located on the northern shore to the east and west of the village of San Cristoforo, are protected.
The Reserve is also a Special Area of Conservation and is one of the protected areas that make up the Brenta River Reserve Network.
