Nestling in a green environment, the Chalain lake is a magnificent water pond of glacial origin that is 2,9 kilometres long and 1 kilometre wide. This lake is particularly well-suited for watersports activities. Its sandy beaches are perfect for those who love lounging around.
On-site excavations uncovered the remains of lake dwellings. These findings can be observed in the archaeology museum of Lons-le-Saunier.
