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!

Beautiful cave and at the northern exit there is even a waterfall and another picnic area (in the shade, more for summer, in winter we prefer to picnic at the southern exit!)

A place full of charm: a unique cave with the road passing under the rock: you have to go through it, and go through it again!

Saint-Martin-d'Oydes is a small commune located in the south-west of France, in the Ariège department in the Occitanie region and is part of the Community of communes "du Pays de Pamiers". Saint-Martin d'Oydes, a remarkable fortified site, is the only circular village in Ariège. This medieval shape, called "elliptical" or "circular", has remained completely intact. Its houses are grouped in a ring around the church. For a few years Tony Blair, then British Prime Minister, came to spend his family holidays in Saint Martin d'Oydes and even inaugurated the village's Tourist Office. He stayed in the 12th-century fortified castle... Its church and the Saint-Anastase fountain, a local pilgrimage site believed to be miraculous for the eyes.

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.
