About Dinant

Dinant sits on the Meuse in southern Belgium, under a citadel reached by cable car and a collegiate church with a distinctive pear-shaped tower. The town is the birthplace of Adolphe Sax, and the saxophone appears on its bridge and in a small museum; Leffe beer was brewed here for centuries. Boat trips run along the river, and the Bayard rock, Namur and the Ardennes are close. May to September suits river cruises and walks, while December brings a modest Christmas market.
