Imagine... Your professor asks you to follow him, because he is going to explain something. He walks straight towards a bush. Then, all of a sudden, he is vanished and gone! It turns out that the entrance of a cave is hidden under the bush. This really happened: in the picture you see us descending into the cave, following the professor.

The cave is situated at the "Causse du Larzac", a few kilometers west of the town of "Millau". In fact, this was our last stop in the wonderful region of the "Causses".
