Perfect for beginners, offering a gentle introduction to the underground world.


Ready to play at being explorers? The Tanne du Névé caving hike immerses you in a mysterious setting, shaped by water and time. Ideal for a first underground experience with family or friends, this outing combines walking with underground exploration.
After a 30-minute approach walk through unspoilt natural surroundings, you’ll enter the cave for 1½ to 2 hours of underground exploration. With a head torch attached to your helmet, proceed step by step, observe the stalactites and stalagmites, feel the dampness and listen to the murmur of the rock.
There are two options available:
Kitting out properly for caving
To explore the Tanne du Névé safely, here’s the essential checklist – because the adventure starts with the right kit:
Average temperature in the cave: 10 °C all year round.


Right before your eyes, nature has been at work for thousands of years, sculpting these formations and galleries. A stalactite grows by just 1 centimetre every 100 years. A single gesture, a touch, can destroy in a matter of seconds what nature has taken centuries to create.
So, take the time to observe, to marvel… and to respect this fragile world. Your care today ensures that others will be able to experience the same sense of wonder tomorrow.
Why not make the most of your visit?
