De Kluft Marina (O. v.d. Berg)

De Kluft sits right on the border of Overijssel and Friesland, giving you a genuinely rare position in the Dutch waterways — two provinces on your doorstep at once. The marina is tucked into the Weerribben-Wieden National Park, so you're surrounded by reed marshes, open polder skies, and serious quiet the moment you tie up. The nearby village of Ossenzijl is tiny but charming, and the broader Steenwijkerland region gives you plenty to explore by bike or by boat.
