The path is strenuous but worth it. Be careful on your head on the stairs.

"The Lourdes Cave was built in 1905 by Father Marqueyrol (former priest of St Montan) after his return from a pilgrimage to Lourdes and has long remained an important place of pilgrimage. Several miracles are said to have occurred there. Apart from its picturesque appearance, this place seems to have been visited very early on due to the springs connected to caves, rocks and the nearby forest. The most important spring, which never runs dry, is called the "Fever Fountain" (Montanus gave it the power to cure fever); we can see it bubbling up from under the road near the small dam." Very worth seeing

One of the most beautiful show caves in the Ardeche. For extra money, tours can be organized in parts of the caves that are not show caves. From 50€.
