ボーム・レ・ダムの峡谷・トップ6

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.

The cave was discovered on June 18, 1978 by the GS Clerval cave association. One of the most beautiful caves in the French Jura. The total length is 6 km. The cave has been closed since the discovery and only for organized cave explorers accessible to us with accompaniment.

The beautiful cave was discovered on June 18, 1978 by the cave association GS Clerval. One of the most beautiful caves in the French Jura and has a length of 6 km. You hike in an underground stream which is only a few centimeters deep and admire bizarre stalactite jewelry. The cave is locked and only accessible to organized cave explorers.

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.
