No, you’re not dreaming! The road out of the village of Mas d’Azil does indeed pass through a tunnel in the middle of this imposing, graying limestone cliff.
So there you are, nose to nose with the northern entrance to the Grotte du Mas d’Azil and the river that gushes out of it. The road tunnel has been there for over a century and a half, so yes, let me reassure you, you can rush right through it!
The crossing is surprising and sometimes even frightening when you’re driving… It’s a first encounter with the beautiful Ariègeoise. Keep your eyes peeled for a dazzling exit from the tunnel… and that’s just the beginning!
