Due to its karst nature, the territory has no superficial hydrographic network. On the contrary, its very accentuated karst nature which variously modelled the territory creating extensive plateaux, deep gorges, steep rock faces, grottos, swallow-holes, dolines and large cavities. Not to mention spectacular amphitheatres, scree extensions, moraines and karst lakes in the Prati del Sirente, Prati di Canale and at dell'Anatelle, near Rovere.
Moving from the north-east are the Campo Felice, the Pezza and the Rocche Plateaux, the Sirente Meadows and the Canale Plains.
