Beginning in France, the Ardennes stretches east across Luxembourg and Belgium before continuing on into Germany, covering three Belgian provinces en route. The most popular corner lies between Dinant, La Roche-en-Ardenne and Bouillon. This gorgeous region is characterised by its river valleys: deep, wooded canyons and beautiful green peaks. Underground is equally impressive with large cave systems like the Grottes de Hotton to explore. But it's not all about the countryside there are great cities to discover, as well as battlefields and even space centres!
