One of the oldest port towns in the Netherlands, Harlingen has a rich maritime past. The Hannemahuis Museum is a treasure trove of local history and the golden age of Dutch seafaring. Visit the Harlinger Pottery and Tile Factory to witness traditional craftsmanship in action. If you’re after a leg stretch before or after a voyage, the iconic Vuurtoren is a lighthouse with stunning views, and the nearby Waddenzee is the largest uninterrupted stretch of wetlands in the world. Fantastic for birdwatching.
