Bikepacking trip with a night bivouac on the shores of Lac des Rousses, beach side. Very windy at night, so wrap up warm. Otherwise, a magnificent lake with few people (early August).

A very nice border village to relax in after a bike ride (from Geneva in our case). We spent the afternoon and a night camping near the lake. Shops nearby for supplies 👍
