Anguillaja and Fatonero are two ditchs of the Apuan Alps, located in the southern slopes of Mt. Sumbra (1765 m) and Mt. Fiocca (1709 m) in part, about 650 m away from each other.

ditches are left tributaries of the Turrite Secca stream, which in turn is right tributary of the Serchio river.

the channelled swirling waters have dug in their rock bed spectacular largecavity-shaped pot, better known as the Giants' pot-holes.

are presented to the viewer as regular cavities, roughly circular in shape, with very smooth walls and a cap shaped bottom mostly.

Anguillaja and Fatonero’s pot-holes are naturally carved into the rock and their size is extremely variable, ranging from a few centimetres in diameter up to 6.6 m, and the depth of 1.6 m.
