With hundreds of castles and chateaux in Belgium, open to the public, it's hard to know which ones to visit. The castle of Freÿr, in Wallonia, is a great place to start.
This grand building has remained in the same family for 20 generations and one wing is still home to the current owners.
Exploring the interior of the castle is a must, as you'll be visiting some of the same rooms as Louis XIV and the Archduchess Maria-Christina.
The best place to take in the scope of the castle and its grand formal gardens, however, is across the river. You'll need a good GPS or map to find the 2 unmarked lookout points. You'll be rewarded for your diligence by this spectacular view.
