Grotte de Han
This giant limestone cave hollowed out by the Lesse (over 15 km) served as a refuge from the late Neolithic period to the 18C. It has huge concretions (5m-long Minaret stalagmite) and magnificent galleries, such as the Salle des Mystérieuses, the Salle d'Armes, which the Lesse runs through and featuring a sound and light show, the Salle du Dôme, where you see a torch-bearer shoot down the enormous chamber. Boats take visitors back to the Trou de Han.
