At 1222m above sea level, near the Fulla Pass, is the source of the Santerno River. The river runs 99km across the Tuscan-Emilian Apennines and into the Reno River. Between the valley of Firenzuola and the town of Camaggiore is a stretch of beautiful landscapes which are particularly well suited to swimming. Every summer the river is frequented by numerous locals and tourists who come to relax in this natural environment which seems as though it were made for swimmers with natural pools, waterfalls and smooth white rocks which are perfect for sunbathing. Just before Pieve di Camaggiore is an old stone bridge which was built in 1700 at the request of Granduke Leopold to lower the number of accidents and drownings that happened to onlookers every time the river flooded.
