All year round

A major underground river in the Ossau valley


The Eaux Chaudes cave is an ideal place to discover caving for a day.
A short approach walk to reach a very large entrance, an underground river with a regulated flow (hydroelectric catchment), varied underground landscapes, a few more technical obstacles (climbs): all the ingredients to project yourself into the bowels of the earth with wonder.

However, exploring the cave requires a good physical condition as it is not a simple walk on flat ground: the walking parts are always in a chaotic environment and require, for example, constant use of the hands to balance.
