This region is home to numerous sinkholes, where flowing surface water from streams disappears into cracks in the chalky subsoil, emerging much lower down in the landscape. The most famous is the Chantoir in Olne. The Ry de Vaux stream disappears into the subsoil here, flowing through an underground cave system and reservoir. It is fed by other surrounding water and re-emerges in several karst springs in Vaux-sous-Olne, 760 meters further and 60 meters lower!

Also called Château Chrouet, after Dr. Warnier Chrouet, who had it built around 1700. Its facade was kept simple. At the rear, large windows overlooked the green Vesdre valley from the hill. A striking feature of the facade is the 17th-century entrance portal in carved limestone with a canopy (canopy) above it. This was typical of many buildings of that period in Olne and was locally called a "teutê." We also see some on the cemetery portal and the municipal garden, but most have been lost over time. The castle's teutë was embellished with a charming turret.

The Olne sinkhole, where the Ry de Vaux stream plunges into the subsurface, emerging 60 meters lower in Vaux, at various points, and then reemerging nine days later. It flows through an underground cave system, flowing through other water bodies and a reservoir.

Coordinates: 235.87/139.12/85 The cave is located on the Esneux-Tilff road, on the right bank of the Ourthe River, 1 kilometer before entering Tilff. The large entrance is approximately 20 meters above the road, at the foot of a very steep limestone cliff. This cave has been known for a long time: it was discovered during quarrying in 1837. In the 1960s, the "Réseau Lemaire" was discovered; an upper level with beautiful calcite pools and a lake. Source: https://www.scavalon.be/avalonnl/fiches/fich23.htm
