The largest karst lake in the Lazio region, Lake Canterno is in the heart of the Ciociaria, not far from the city of Alatri. It is situated at the foot of the Ernici Mountains and surrounded by woodland.
Located at 538 metres above sea level, it is set in a landscape of rolling hills and protected by a nature reserve by the same name. It covers a surface of 0.6 square metres (2 km long and 1 km wide), has a 5-kilometre perimeter and a variable depth between 13 and 25 metres.
The atmosphere of this small natural basin has been compared to the fabled aura of the Scottish highlands. Images of elves and medieval legends seem to surface from the calm waters of this lake.
The fish of this lake are carp, eel, European perch and molluscs of the Anodonta Cygnea kind. .
The avifauna is typical of the wetlands: grey heron (ardea cinerea), purple heron, the little egret (egretta garzetta), common moorhen (Fulica atra) and the great crested grebe (podiceps cristatus).
Birds of prey are also present, such as the common buzzard (buteo buteo), the Eurasian sparrowhawk (accipiter nisus) and the Eurasian eagle-owl (bubo bubo).
The welcoming and healthy natural environment of the lake makes it an ideal destination for those who love the outdoors, being in contact with nature and physical activities.
The many trails around the lake are suitable for bicycles and walking. This is where you can fully enjoy the extraordinary quietness and enchanting panorama.
The best side of the lake is certainly the south-east side, which faces cultivated fields. Instead, the side towards the mountain, due to the presence of the Fosso del Diluvio, is defined by marshes which make it difficult to reach the lake.
