This is the highlight of the show in Ariège! The Grotte du Mas d'Azil is one of the few caves in the world to be entirely crossed by a paved road (the D119) and by a river, the Arize. The visual contrast as you enter under this immense rocky porch is absolutely striking. Whether you are on a bike (road, gravel) or on foot, the atmosphere is grandiose, fresh and enveloped by the sound of water. It is also a major world-renowned prehistoric site that gave its name to the "Azilian" culture.

A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

Don't trust the no trespassing sign. Private property! Danger of death prohibited! We almost missed it because of those two signs! You have to be careful, yes, like everywhere! But to put danger of death 🙄! Plus, there's a lifeline where there would be danger! But honestly, we didn't see any danger! Done with an 8-year-old, no problem!

Beautiful cave and at the northern exit there is even a waterfall and another picnic area (in the shade, more for summer, in winter we prefer to picnic at the southern exit!)

A place full of charm: a unique cave with the road passing under the rock: you have to go through it, and go through it again!
