This is a rather long trail, with a total length of six kilometers and it takes about four hours to walk the trail and visit all the sights. You should plan at least half a day. However, for the lazy there is a road cutting through the trail which offers a shortcut for the way back. Starting at the car park at the D4 near Besain, the trail is marked with a cartoon of a Neolithic man and red stripes on the rocks.
The first stop after ten minutes is a cave, Le Fountaine à Coupot. It may be entered on a path with a handrail. The next part of the trail is somewhat weird, as 70 strange faces were painted on unusual rocks along the way. The Gouffre Pédagogique (Teaching Pit), is a spectacular entrance into a cave system which is used for training purposes by the local caving club. It is not possible to visit this vertical pit, as this is far too dangerous without appropriate climbing gear. The cave is fenced.
The Gouffre des Arcades (Pit of the Arches) is horizontal, despite the name, and safe to enter and explore. It is named after several magnificent limestone arches. The next cave, La Loge à Maillet is a through cave. It is longer than the caves before and a torch is necessary. This cave is definitely fun for children, who may get a first taste of real caving.
The path now crosses the D4, which allows to go back to the car park, about 400 m along the comfortable road. The rest of the trail follows on the other side of the road.
The Lapiaz de Besain is a typical karren field. The patchwork of limestone clints forms a confusing labyrinth of ridges, and it is easy to confuse the way. Just follow the caveman signs sternly. After two more caves, a huge one which is unsigned and Le Grotte de St Bilba, with a trail with handrail, the next karren field follows. Les Tables de Lapiaz are not covered by soil and vegetation, this is a piece of bare karst. Here the path often uses narrow gorges between the limestone plates, and a little climbing may be necessary. After the end of this limestone pavement, the path soon reaches the car park.
