Although the castle is in ruins, most of the walls are still standing and some rooms are still well preserved (especially the fortified chapel in the Lower Castle). For the brave and the hikers, a long hiking trail leaves the village of Duilhac (take the castle route for a few hundred metres before taking a small path to the right which has hairpin bends). It is a variant of the Cathar trail. During storms or high winds, the climb is strongly discouraged and often prohibited to protect the visitors from lightning and dangerous falls in the St. Louis staircase, which connects the former castle to the dungeon, already highly slippery in good weather. The limestone cliff is ideal for rock climbing and all (or almost all) of the routes reach the surrounding wall, a great pleasure for rock climbers who finish their ascent under the watchful eyes of tourist onlookers.
