The Lagustelli di Percile: two lakes in the heart of the Monti Lucretili Park
The Lagustelli di Percile are two small lakes located in the Monti Lucretili Park, in the Ustica Valley. A wetland protected under the RAMSAR international convention — one of only six in Lazio — they owe their origin to collapses caused by underground water erosion. Two bodies of water that are different from each other yet just a few steps apart, surrounded by dense woods and silence.
The large lake
Lake Fraturno is the only accessible one. Its shores are colonised by poplars, marsh reeds, horsetails and willows, with small sandy banks where you can stop and rest. Just above, on Colle Morella, lie the ruins of Castel del Lago — one of the medieval fortresses that once guarded the Ustica Valley.
The small lake
Lake Marraone, the smaller one, is shaped like an enormous funnel, half-hidden among the trees. You can only look at it from above, leaning over a wooden fence: climbing down the steep banks would damage the ecosystem.
Practical information
The lakes can be reached on foot or by mountain bike from Percile, but also from Licenza, Mandela, Riofreddo and Cineto Romano, along various trails.
