the prehistoric cave of Sare

Reservations are highly recommended. The purchase of tickets remains possible on site, for the same day, if there are still places available.

In the bowels of Atxuria

The clay layer at the summit of the Atxuria Mountain, in which the cave has formed, limits rainfall infiltration, which gives the many cavities it shelters an original geological formation.

One of them, called LEZEA or CAVES OF SARE, can nowadays be visited almost as it was over 2 million years ago !

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.

Natura 2000 classified site

Today the Grottes de Sare are part of the European Natura 2000 network. The aim of this network is to maintain the biological diversity of the environment via a sustainable development approach.

The Grottes de Sare are located within the Larrun - Xoldokogaina massif, which includes various forests, moors, wetlands, caves and cliffs plus rich and varied flora and fauna with some endemic species. Stag Beetles, White Claw Crayfish, Quimper Snail, Rosalia longicorn, Hairy Soldanelle, Drosera, and many others are all to be protected around the Grottes de Sare, without forgetting the different species of bats that are regularly monitored in the caves.

This designation allows us to better know and conserve our natural heritage.
