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

Creux Billard is a mighty valley with a diameter of around 60m, with sides rising 90m high. There is not much of a spectacle here like at the Lison waterfall - the place impresses with its dimensions and (if there is any) with its silence (but the echo is also good)

Huge cave entrance and the short tour until you can't go any further is worth it.

The canyons around Saraz, particularly the Gorges du Lison, are rich in natural wonders. You can explore the majestic Sarrazine Cave, a 'wild cathedral' carved into limestone, standing 100 meters high and 30 meters wide.

Don't miss the serene Lison Waterfalls, where the river flows between gorges, creating calm waters and small tuff waterfalls.
The best time to visit depends on what you want to see. For the most impressive waterfalls, such as at Creux Billard and the Source du Lison, it's best to visit after significant rainfall. However, be aware that the Sarrazine Cave can be tricky to explore deeper parts after rain due to water levels.
