Caves of Han-sur-Lesse

Caves in Wallonia, Belgium

The Caves of Han-sur-Lesse (in French: Grottes de Han-sur-Lesse or simply Grottes de Han) refers to a natural complex of caves in Belgium. A major Belgian tourist attraction (around 250-300,000 visitors per year), the caves are located in Wallonia, on the outskirts of the village of Han-sur-Lesse. The caves were formed as the result of an underground erosion of a limestone hill by the river Lesse.
