1818 Count Robiano tried to find a route through.
Dec 1964 Guy Deflandre unexpectedly discovered Santa Claus Cave.
1968 the Belgian diver Daniel Ameye disappeared in the Gouffre de Belvaux.


The Grottes de Han-sur-Lesse is a cave system which forms part of the subterranean river Lesse. The river disappears in the Gouffre de Belvaux and reappears 24 hours later on the other side of the hill near the Trou de Han.

At the beginning of the sixties, divers discovered an archaeological treasure trove on the riverbed.

The cave is a major tourist site and thus well developed. Numerous attractions make it worth a whole day visit. Beneath the caves is the Museum of the Subterranean World with a prestigious collection of archaeological remains discovered in the cave. Then there is a railroad ride, a wildlife reserve and the Expotheme, an exhibion on the Maasai.

The cave has three stars in Guide Michelin, and is so proud of it! In my eyes this says much about the manner, in which the cave is administered.

Visit the caves by tram, on foot, ... and by boat! From the centre of the village, a small picturesque tram will take you to the cave entrance. Multilingual guides will help you discover chambers, each one more beautiful than the last. The superb Minaret, the fascinating Mystérieuses, the Weapons Room and its son et lumière, the huge Dome Chamber and its new lighting and finally the highlight of the adventure, a boat trip on the underground river.
