La Roche Percée

Highlight • Natural Monument

Located near Artemare, the Cerveyrieu waterfall is impressive with its wide curtain of water cascading down from a limestone cliff. This site, classified as a "sensitive natural area," is ideal for a break.

The climb from Jongieux le Haut is still very pleasant, and at the chapel you are rewarded with a beautiful panoramic view. The descent to Yenn can be very slippery in rainy weather; a warning sign is posted along the descent.
