a pretty spot. unfortunately, the lake shrinks a little more every year, just look at the distance between the pontoon made to allow people with reduced mobility to fish, and the water... . ideally, walks in the Esterel are easy, at the beginning of spring. it's green, and there are many "streams" along the walks... in July this year (2025) the massif was closed to access most of the time, because of the risk of fire.

Not sure of the name, but nice lake, with frogs (at least, in spring). Ideal for a picnic.

Like all esterel it's great. In the morning not too late because even in September things hit quickly. The typical fire truck access paths are therefore cool and very smooth. Too rolling sometimes, because Be careful of the lack of grip for those who come from 'greasy' regions where it sticks. My elbow will take a few days to recover

You can’t go around the lake, the path is close to it on just one side. Worth it, regardless!
