The area comes with a very evocative atmosphere, with the Strolla stream having eroded the basaltic rocks into new shapes. It’s located around the upper basin of the Era river, and it forms a sort of green island immersed in the big farming areas on the hills dating back to the Pliocene epoch.
An old church called Pieve della Nera overlooks the valley of the Strolla stream. Not far away from the church, one can admire the remains of the medieval Della Nera castle, located on a small plateau where the outcrops of limestone used to work as a natural defense system for the castle.

Outside the reserve, right before the Pieve, is where the Fonte del Latte is, a spring that, according to the legend, provides young mothers with a magic water which gives them milk.
