The source of the Loue River is announced by the rushing water even before you see it. It's impressive and magical to stand beneath the 150-meter-high cliffs and watch the river rush out of its cave.

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.

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

Very beautifully laid out and developed. There are also interesting information boards, e.g. about the underground connection of the local springs. At the end of the 19th century, a mill owner wanted to divert the water from the spring, which, after intervention by the population and a member of parliament, led to the first French environmental protection law. https://www.montagnes-du-jura.fr/
