Grand Lac, Lake in Clairvaux-les-Lacs, Jura, France
Grand Lac is a natural lake in Clairvaux-les-Lacs, in the Jura region of France, listed as part of a UNESCO World Heritage Site and classified as a historical monument. It is about 0.4 miles (0.65 km) wide and just under 0.8 miles (1.25 km) long, sitting at roughly 520 meters in elevation.
Around 6,000 years ago, early communities built villages on stilts over the water at this site, leaving behind wooden tools, seeds, and bones that archaeologists have since uncovered. In 2011, these ancient lakeside settlements were officially recognized as a UNESCO World Heritage Site.
In summer, the Grand Lac becomes the center of village life, with families coming to swim, pedal-boat, and paddle on the water. The sandy beach has a gentle slope, and a specially designed beach wheelchair is available for visitors with reduced mobility.
The lake is open for swimming in summer, and the beach is supervised by lifeguards during the main season. A paid parking area is available near the beach, so arriving early on busy days is a good idea.
Though the lake is known today for swimming and water sports, it is considered one of the oldest stilt-village sites in Europe. Just nearby sits a smaller lake, the Petit Lac, but it is private and closed to swimming or fishing.
