A modest, but azure, body of water surrounded by steep green hillsides, on which trees cling precipitously, Lac de Montriond attracts scores of sunbathers in the summer. Most of them cluster around the shallow outdoor pool, leaving plenty of space on the grassy banks of the lake proper. It is a very pleasant 3km walk or jog around the circumference of the Lac de Montriond. Or you can go for a swim, once you have waded through the muddy shallows. On site, there are toilets and a couple of places to eat. When temperatures rise into the thirties in the Alps, the Lac de Montriond offers a scenic reprieve, but parking can be tricky.
