Réservoir de Grosbois

The Grosbois Reservoir is an artificial lake spanning 105 hectares with a sandy beach and clear water reaching depths of 22 meters at its deepest point. The water is divided into separate zones for swimming and fishing activities.

The lake was created in 1838 to supply water to the Burgundy Canal, serving as a key infrastructure for the region's water management. In 2007, it underwent its first complete emptying for maintenance operations.

The reservoir serves as a gathering place where swimmers and anglers share the water, and a seasonal beach cafe brings together visitors enjoying regional food. The site has become a social hub where people unwind and experience local flavors.

Swimmers should use the supervised areas where lifeguards are on duty, while fishing zones are clearly marked and kept separate from bathing areas. It helps to check which zones are accessible on your planned visit day.

The lake contains two shallow zones densely covered with water plants: one completely restricted to protect nature, and another open to anglers. These protected areas provide a glimpse into habitats for rare aquatic wildlife and plants.
