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!

Hike with breathtaking views. Be careful not to get too close to the abyss because it slips in winter...

The Nerech waterfall is one of the most powerful in the Pyrenees. It flows into the heart of Couserans (vast territory combining high mountains, mountains and foothills, and covered areas). It is home to rich biodiversity. Among the species most observed here, there is a very wide variety of wild orchids.

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.
