Grottes de Neptune

Grottes de Neptune, sometimes known as The Grottes de l'Adugeoir, are a collection of natural caves in Wallonia near Petigny, in the municipality of Couvin, Belgium. They are situated on the Eau Noire, a branch of the Meuse River. The Caves of Neptune are unique in that you don't simply walk through the caves; you also get to see the grandeur of the rocks from a small boat!

A 50-minute guided tour will take you on a boat and through a music and light show, making for an unforgettable experience. A 1.5-kilometer instructive walk through the woodlands above the caves, a playground for youngsters up to the age of 12, and many long walks are also available in the area.
