The Avigliana lakes are two small lakes of glacial origin, created from water buildup in the spaces between several concentric frontal moraines which the glacier of Val di Susa, after the ice age, produced in his retreat to mount. Separated by a narrow isthmus, are located in the municipality of Avigliana (TO) and based on their surface are called big lake and small lake. The marshy area around the Lakes went to form the Avigliana Lakes nature park since 1980 and is home to numerous species of birds including herons, mallards, coots, loons and moorhens.
