Noordpolderzijl is the smallest sea harbour in the Netherlands — a place so small it barely registers on a map, and all the more remarkable for it. There is just a landing stage for a handful of boats, a pumping station, and a single building: 't Zielhoes — an old café that doubles as the village itself.
The harbour sits in the far north of the province of Groningen, in direct tidal connection with the Wadden Sea. Only shallow-draught vessels can enter at high tide. The name tells you exactly what it is: the zijl (sluice) of the Noordpolder — a low-lying stretch of reclaimed land protected by dikes, at the very edge of the Netherlands.
Getting here requires a little effort, but that is precisely the point. The landscape on the approach — flat, open, scoured by North Sea wind — prepares you for a harbour that feels genuinely at the end of the world. Locals know about it; tourists almost never come. That is reason enough to visit.
