グラモンダンの峡谷・トップ5

Driving along the Doub is wonderfully relaxing - just don't forget to take something to eat with you! A gastronomic service desert!

Cannot be reached directly from the cycle path.

High grotto with wonderful limescale deposits - accessible via a metal ladder even without equipment. The grotto does not lead deep into the rock, the daylight is sufficient, you do not need a flashlight. It is freely accessible to everyone.

On the other side of the train tracks up the hill are the wild undeveloped karst caves of Fourbanne, a dream for fans of speleology. Bring good light, rugged cloths, and wear your helmet (you're biking, so you have a helmet!). https://inpn.mnhn.fr/zone/znieff/430013670 See video https://www.youtube.com/watch?v=7nxTiEY92I8

The cave is listed as a real classic among speleologists. Through a very small shaft entrance of just 30 x 50 cm. you have to abseil about 7 meters ... Then the next 18 meter deep shaft. A final climbing step, about 5 meters lower, ends in an impressive and large hall with beautiful stalactite columns.

A nice point of view on the Doubs from the cliffs of Deluz. Be careful where you step, the stones are not stable in places! ============== A nice point of view over the Doubs from the cliffs of Deluz. Be careful at the top, rocks aren't stable in some places! https://fr.wikipedia.org/wiki/Deluz
