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 👍

A departure from Lac des Rousses towards Le Pont and back. A not-too-difficult outing of 62 km and 450 m of elevation gain.

A stronghold of resistance and an ancient milestone on the Sardinian road that led to the Netherlands in the 17th century. A very beautiful view of the Jura Mountains, too.
