The Arville Cave is located near Arville Castle in Faulx-les-Tombes and consists of several smaller cavities collectively known as the "Arville Caves." The most famous cavity is the actual Arville Cave (also known as the Trou du Chantoir), which is located on the northern slope of a paleokarst depression. This depression has a nearly permanent pond at its bottom, the water level of which varies with the seasons. The caves are not open to the public or tourists. They are primarily an interesting karst area for geological and local nature walks.

It's a popular spot for hiking, horseback riding, and mountain biking, as it offers picturesque views of the hills and wooded valleys.
