In March and April, Uniworld offers Belgium river cruises that start in Amsterdam and end in Antwerp or reverse. Visit the trendy city of Antwerp where you can choose go to on a walking tour admiring the city's well preserved architecture and seeing four of Peter Paul Ruben's masterpieces at the Cathedral of Our Beloved Lady, or explore the city like a local. Ride the metro, check out the main shopping district, and visit the historic central station. Not to be missed on this excursion is Diamondland, Antwerp's largest diamond shop. The city is the Diamond Capital of the World, after all.

When in Ghent, choose between exploring Ghent, one of the oldest cities in Blegium or beautiful Bruges, a UNESCO World Heritage Site. Sailings are 10 days long.
