Visited as early as 1893 and fitted out to be accessible for most people, the DEVIL'S BRIDGE GORGES offer the visitor a gripping picture of the power of erosion. The jagged profile of the sides and their shaded coulours give the whole site a weird appearance attenuated by the magnificent surrounding forests.

This defile, partly underground, gouged into very hard grey marble links surprisingly the Leman's Lake area and the CHABLAIS Massifs.
