A small wooden bridge crosses the Vall del Riu river. It's not much more than a stream at this altitude, but it can be very powerful in the rainy season in early spring when the snow melts.

The cave of Niaux is part of what is called the four major prehistoric art. The other three are: "Lascaux", "Altamira" and "Chauvet". It is also very impressive with its monumental entrance and its view overlooking the valley.
