The Lesse tunnels underground here to form magnificent caves that are the region’s biggest tourist draw. Guided visits (English often available) start after a 10-minute ride in charmingly rickety open-sided tram cars. Then you take a 2km guided stroll through a succession of impressive subterranean galleries, each well endowed with stalactites and especially fine draperies (beautiful translucent ‘curtain’ formations). The climax of the visit is a short sound-and-light show and cave whose stalactites reflect beautifully in the water.
Gradients and steps aren’t especially challenging but dress appropriately (13°C) and allow around two hours. May to August departures are every half-hour, dropping to hourly off season. The ticket office is on the main square along with Han’s grey-stone church and a tourist office that rents out bicycles.
