The cave Grotte du Château de La Roche (Cave of the Castle Rock) was named after its location. On the northern side of the Doubs river valley are some limestone cliffs with enormous cave portals, which can easily be seen from the valley below. There is no castle, but the rock with its cave openings rembles a ruined castle. The cave has several level, and while the huge upper entrances end rather soon, the lowest level, which is also the resurgence of a tributary to the Doubs river, has some legnth. However, river caves are very dangerous and should not be entered. The dry caves have flat floor and may be visited easily on a hike.
