Remember not to venture too far into the cave

The village of Nans-sous-Sainte-Anne is remarkable for the scale of its landscapes, the rhythm of the mountains and depressions. It knows how to combine in a restricted space the charm of the foliage and the fir trees with the austerity of the rock walls, the impetuosity of the waterfalls with the intimacy of the undergrowth, the mystery of the caves with the picturesqueness of the belvederes.

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

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/

Very beautiful waterfall, easily accessible from the car park and then offering several hiking possibilities from its basin. The site is geologically interesting.
