If you enjoy landscape rather than – or in addition to – cities; from my experience, Belgium “has its merits”. The northern part of the country contains many culture-rich cities, but is scenery-wise very flat and dull. The southern part of Belgium has some beautiful scenery – the Ardennes in the country’s south-east (the cave-complex – tours [some in English] given “on all days” – at Han-sur-Lesse, is fascinating if you like that sort of thing); and the IMO exquisite corner close to the French border, around Couvin and Chimay south of Charleroi. Namur, in the south of Belgium, is a fascinating city with a centuries-old fortified citadel – tours of same can be had, some with, as at Han, an English-speaking guide. (My impression is that Belgians are very good with languages – anyone in the tourist trade seems to have a good command of French, Flemish, and English.)
