Top 5 Caves シャンプリーヴでの

The three Arcier springs are fed by the infiltration waters of the Nancray plateau. Shortly after they gush out of the mountain in beautiful waterfalls, they come together to form the Arcier stream, which quickly flows into the Doubs. They have been known since antiquity, and supply Besançon with water via a Roman aqueduct of which remains remain. Currently, a trout fish farm benefits from its pure, fresh waters.

Cannot be reached directly from the cycle path.

The sources of Arcier are three karstic sources resulting from a hilly circus of trees and green forests. They meet after 300 meters and flow into the Doubs. Natura 2000 site, the spring water comes from the natural drainage of the watershed of the Saône-Nancray plateau and is filtered by the Saône marshes.

After a small barrier and a small climb comes a nice point to rest. Attention, it is not recognizable at first glance. Behind the bush is a very small 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 small detour to the source of Arcier, watch out for hikers! You will be able to see the castle of Arcier there as well as the ruins of the old Roman aqueduct of Besançon. ============= A little detour to the source of Arcier, beware of the hikers!
