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

Narlay Lake, located in the Jura, is a true natural setting surrounded by forests and green hills. This glacial lake, with its clear waters, offers an idyllic setting for a walk or a contemplative break by the water. The paths that surround it allow you to explore its peaceful banks, offering superb views of the Jura mountains and the reflections of the landscape in the lake.
