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.

You follow Arize, cushy, when you wonder where you're going to end up getting out of this valley, and there, BOOM, THE BIG HOLE. Spectacular. In the water, it's noisy and dark. Stay focused on the road, the gutter is cruel.

Nice climb on bitumen from Castelnau-Durban to reach Balès and a magnificent and balaise (steep) grassy track to join the forest of the Col de la Rille. Passage to the Croix d'Esplats, characteristic for its pink marble base. Be careful, the Tour de la Crie hiking trail is very stony and requires a few pushes… You can avoid it by staying on the road but you go down to go back up.
