The caves serve as the resurgence point for the Bèze river, which originates from an underground network still partially unexplored.
The subterranean river tour relies on a boat to navigate the final leg of the visit, which is a rare feature for French cave systems.
Bèze village is officially categorized as a 'Petite Cité de Caractère' due to its preserved historical heritage.
The cave system maintains a constant interior temperature of 12 degrees Celsius regardless of the external climate.
The Grottes de Bèze are limestone caverns located in the heart of the village of Bèze, notable for their underground river system. Visitors explore the site through a combined walking tour and a boat ride on the subterranean water. The cave system is formed by the resurgence of the Bèze River, which flows through a network of stalactites and stalagmites. The water inside remains at a constant temperature year-round. These caves were naturally excavated by water erosion over millennia. The entrance is situated within the historic village perimeter, classified as one of the most beautiful villages in France. The site showcases geological formations including diverse crystalline structures. The cave tour concludes with a return to the surface via a short boat journey.
The underground lake area where the boat tour concludes provides the best lighting and reflections for photography.
Bring a jacket as the interior temperature is consistently cool even during summer heatwaves.
Wear sturdy, non-slip footwear as the ground inside the cave can be damp and slippery.
Book your visit in advance during peak summer months to ensure space on the boat, as capacity is limited.
Do not attempt to explore the river banks outside the guided tour areas, as the water levels can fluctuate unexpectedly.
Open seasonally from spring through autumn; closed during the winter months.
No flash photography is permitted inside the caves to protect the ecosystem and prevent algae growth on the rock formations.
