One day
Start on the Markt and climb the belfry for the rooftop view, then see the Burg and the Basilica of the Holy Blood next door. Take a canal boat trip, walk to the Church of Our Lady for the Michelangelo Madonna and the Groeningemuseum for the Flemish masters, and end at the tranquil Béguinage and the Minnewater as the day-trippers leave.
