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!

In this magnificent prehistoric cave, crossed in its entirety by both the Arize river and a road, prehistoric portable art dating from the Azilian was discovered. The most famous of his sculptures is undoubtedly the spear-thrower called the bird fawn. In the middle of the cave, a museum opens its doors to visitors. Come and learn a little more about this period of the Upper Palaeolithic. Be careful when crossing the cavity. A good lamp is mandatory, because some parts are very dark and the pavement on the side can be treacherous.

By this detour, you avoid going through the road that crosses the cavity right through. It is certainly one of the most beautiful views of this unique cave.
