Lezea, the cave of Sare

Lezea cave

The huge limestone massif of Sare and its surrounding area has numerous cavities. One of them, called LEZEA or CAVES OF SARE, can nowadays be visited as it was over 2 million years ago!

The clay layer at the summit of the Atxuria Mountain, in which the cave has formed, limits rainfall infiltration. You will discover an unusual geological formation… huge rooms with astonishing dimensions, an entrance porch among the biggest of Aquitaine and of course the habitation site and daily activities...

At the bottom of the cave, strange encounters...


The Caves of Sare did not only shelter humans, but also...cave bears which hibernated in the cavity over 10.000 years ago!

Now more than ever, bats are the mammals that have settled in the cavity. Thanks to a collaboration with the Conservatoire Régional des Espaces Naturels (regional association for natural areas), the Groupe Chiroptère Aquitaine (chiroptera group of Aquitaine) and the Espaces Naturels Aquitaine association (natural areas Aquitaine), the site of the Caves of Sare is now listed as a habitat of international interest due to the numerous species that live there.
