Magnificent castle complex. You can see as far as Château de Quéribus and further towards the sea. In summer, flowers grow from every wall and crevice in the rocks.

These are some very beautiful gorges. Note the small medieval stone bridge that seems so fragile. Also know that the thermal spring of La Fou is very close to this magical place.

"Clinging" to the rocks, very unstable 😉 Since the path goes through it, you can't do a circular walk outside of opening hours. From the larger parking lot to the south, you can at least get to the entrance in the evening, with views into the gorge. From the north, the path ends at the end of the tunnel...

The Hermitage Saint-Antoine is a large natural basilica built from trees and rocks and above all brought to life by the sound of water and the song of birds. You will find many works of art there (frescoes, stained glass windows). Access to the site, the tower, and the museum is free.

A dolmen that is worth the detour, especially for lovers of megaliths. Other dolmens are also present around Ansignan.
