The Valley of the Caves of Saulges is a limestone canyon located in the Mayenne department of France, featuring two primary caves open to the public, Margot and Rochefort. The Prehistoric Museum serves as the visitor center, showcasing artifacts found within the site, which document human presence dating back to the Paleolithic era. The cave system is carved by the Erve River, creating a unique micro-ecosystem. Margot Cave is noted for its prehistoric engravings and varied stalactite formations. Rochefort Cave offers a deeper look into geological development and cave fauna. The site sits within a Natura 2000 zone, protecting the diverse flora and fauna of the valley. Guided tours are required to access the cave interiors for conservation purposes. The museum provides context regarding the transition from Neanderthal to Homo sapiens in Western France.
