Lago di Gerosa is a 400 mt large artificial lake, 2 km long. It’s mainly fed by Aso River that goes down from the slopes of Monte Vettore to Adriatic sea. The lake signs the borders among three municipalities: Montemonaco, Montefortino and Comunanza.

Thanks to the large size of the lake, activities such as canoeing, sailing and fishing are frequently organised. In Summer the place is very popular for its small beaches, appreciated by tourists who come here to enjoy the sun and the wonderful views.
The right bank, covered with forests, is the least accessible but it’s perfect to enjoy relaxing walks or to practice Nordic Walking. In the adjacent forest path it is possible to meet some wild mammals like deer, porcupine or badger.
