Beautiful view of the lake, and afterward, we had a lovely swim in the lake. Nice bar with delicious ice cream.

Lake Chalain is a glacial lake (10th largest natural lake in France), where a lakeside city dating from the Neolithic period, classified as a world heritage site, was discovered.*The view from the Fontenu belvedere will reveal its turquoise waters. !

On the heights of the lake, the so-called belvedere of the castle offers you a wonderful view of Lake Chalain and the forests that surround it.

There's nothing like a beach after a long, hot day of hiking. Especially since the turquoise waters of the region's lakes call for swimming. This equipped and supervised beach will allow you to cool off quietly. You will also find something to stay for the night, eat, fill your water bottles, go to the WC. A pleasant and practical beach.
