Grottes de Neptune is entered at a fossil level with beautiful concretions. The tour goes down through another level to a river cave. Here a boat is entered and this lowest level is visited on a twenty minutes boat trip. The cave river is called Eau Noire (black water).
A guided tour takes the visitor on a journey of discovery in a natural setting of stunning beauty, along the foot of shimmering limestone cliff.
A walkway overlooking the wild and meandering river "Eau Noire" [The Black Water], crosses in front of an impressive porch which swallows up the river. The visit continues into the two upper galleries of the Caves of Neptune, with their superb rock formations sculptured by nature. The visit culminates in a 20 minute boat ride along an underground river, 10m below the level of the "Eau Noire". The journey is enhanced with an unusual "music & light" display, which, it is claimed is unique in Europe. During this display there are a number of lively waterfalls which form an impressive backdrop to the scene. The music of Vangélis and the stroboscopic light effects makes this a truly magical event which will live in the mind of the visitor forever.
