In Bèze, the visit begins on foot through natural cave chambers, then continues by boat for more than 300 metres along an underground river. Alternating walking and boating gives these caves a distinctive identity compared with entirely on-foot cave tours.
The speciality: an underground river
The second cave, discovered in 1950, contains the river that feeds the Bèze spring. Since opening to the public in the early 1970s, part of the network has been explored by boat, with a guide explaining both the geology and how the river works.
Around 50 minutes between rock and water
The full visit lasts about 50 minutes. The temperature stays around 12°C. The route is unsuitable for people with reduced mobility or balance disorders, and pushchairs must remain at reception. Animals, photographs and videos are not allowed inside the cave.
Before visiting in 2026
The river level varies and determines the boats' capacity. This is why individual bookings are restricted, particularly at weekends, on public holidays, and in July and August. Groups of at least ten people can book in advance, however.
2026 prices
The complete visit costs €10 for adults, €8 for ages 13–17 and students under 26, and €6 for children aged 4–12. For groups of ten or more, prices are €9 per adult, €7 per teenager or student, and €5 per child.
What visitors remember most about Bèze is the boat ride: after the dry chambers, the pace changes as you explore the cave directly from its underground river.
