The park is home to a 22 km-long coastal sand strip, from the limestone cliffs of the Mount Circeo, in correspondence of the Torre Paola watchtower, up to Capo Portiere. The sand, characterized by fine sand, is backed by a typical maquis shrubland with a maximum depth of 27 meters. The section nearer to the sea is home to short vegetation, housing a number of small size wildlife including the European badger, foxes, lizards and beetles.
