The Grotte des Eaux Chaudes contains without doubt the most spectacular underground river in the Ossau Valley. Thanks to the size of the entrance porch and the volume of its galleries, it was discovered very early on by naturalists, travellers and Pyrenean explorers in the 17th century. Today, thanks to the water catchment inside to produce electricity, we can explore this cave in complete safety, even on days of heavy rain. Ideal for a first or second roped caving trip. So what's up? Are you ready to discover the most emblematic cave in the Ossau Valley?

Exploring the cave does require you to be in good physical condition, however, as it's not just a walk on flat ground: the walking sections are always in a chaotic environment and require you to use your hands constantly to balance, for example.

Organisation : 

You meet your guide in Laruns.
Once the introductions have been made, you will travel by car to the cave car park (10 minutes) where you will get kitted out and begin the attractive approach walk of around 40-50 minutes.
The activity in the cave lasts around 5 hours, including several stops to discover the underground world and a break halfway through for a bite to eat.
The activity finishes at around 5pm.

Level :

Good physical condition - from 10-12 years old - several roped passages guaranteed, the day is equivalent to a good day's mountain walking with a medium gradient. Children up to 16 years of age
