With a surface of just over a square kilometer, the enchanting Lake of Letino was created at the beginning of the twentieth century in order to feed the hydroelectric power station of Prata Sannita.

It rises from Lake Matese and in the first part of its way, it is characterised by cascades and differences in heights.

Once known as Lake of Carinola, it is a volcanic lake at the foot of mount Massico, in the municipality of Falciano del Massico.

For the ancients, it was the river of the myth, which gave forgetfulness to whoever drunk its water.
