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

The spring is simply gigantic and there aren't too many tourists - at least when we were there.

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.
