Remember not to venture too far into the cave

A beautiful valley - very relaxing to drive. La Roche Bottine is the right-hand rock edge that you see above Ornans. It is on the right of Ornans towards Lahier, above the D492 The left-hand rock edge is the Belvédére de Notre-Dame du Mont. Curious rock... its special shape inspired its name: La Roche Bottine   

Here you have a view of three rock masses. The question is which one is the Roche Bottines

The Verneau is an underground river in the Franche-Comté Jura. It collects water from the Déservillers plateau and comes to the surface near Nans-sous-Sainte-Anne before flowing into the Lison. It is one of the largest underground rivers in France. During our visit, we found a notice saying that it is forbidden to enter the area around the spring or waterfall.

This highlight is located on the plateau under which the cave opening is located. It can be found via a dead-end path, but the view is a bit sobering.

The Sarrasine Cave impresses with its 90 m high portal. A 40 m thick layer of limestone separates it from the upper part of the plateau. The cave system has been explored for about 4 km, and hikers equipped with a flashlight can access it up to a small lake inside. https://www.lieux-insolites.fr
