If you’re in the mood for a little more adventure, keep on cruising to Antwerp, 20 miles from Olen. There are plenty more fabulous things to see and do here, including Antwerp Zoo and Antwerp Market Square. Nothing screams fun like a road trip does, so keep on driving to Brussels. It’s 30 miles away and also has a few worthwhile sights, such as Atomium and La Grand Place.
