You're off on a choice of excursions this morning. One brings you to flemish city of Bruges, known as "the Venice of the North," for its canals and tiny medieval streets; have lunch in town. On your walking tour in cobblestoned, fairy tale-like Bruges, you'll feel like you've walked into a painting by Jan Van Eyck, who captured life in the city during its heyday in the 15th century. The hike up the stairs of the medieval bell tower is well worth the effort; you'll be rewarded with wonderful panoramic views. The other choice brings you to another flemish city, Ghent, for a walking tour through its Old Town; the pedestrian-friendly cobblestoned town center feels like an outdoor museum of early Flemish architecture. Think about climbing to the top of the 14th-century belfry, crowned with a dragon, for the view – Ghent laid out before you is a visual feast of castles, churches, and historic merchants' houses. Be sure to try the local specialty, Ghent noses, a traditional raspberry candy sold at stands on the street – or a warm waffle with sugar or honey. Your final choice is a bicycle ride into the Belgian countryside alongside a local guide. Have cocktails and dinner onboard as your riverboat charts a course towards Gorinchem.
