Noordpolderzijl

Noordpolderzijl consists of a sluice, a small tidal harbour, a nineteenth-century inn and nothing else - it is generally described as the smallest seaport in the Netherlands, and it is behind the Wadden dyke on the Groningen coast where the land ends and the mudflats begin. The zijl is the sluice that drains the polder into the sea, and the harbour beside it dries completely at low tide, so the handful of boats sit on the mud for half of every cycle and float for the other half. 't Zielhoes, the inn on the dyke, has been there since the 1800s and serves the walkers and birdwatchers who come out here. What the place gives is emptiness: standing on the dyke there is polder behind and, in front, the whole flat expanse of the Wadden Sea to the horizon, with the tide running out to nothing.

What you actually see

• The smallest seaport - a sluice, a tidal harbour and one inn.
• A harbour that dries out - boats sitting on the mud for half of every tide.
• The dyke horizon - polder behind, the whole Wadden flat in front.
• An inn from the 1800s - 't Zielhoes, the only building here.

When to go

April to October. Half a day.

Honest expectations

There is genuinely nothing here but the dyke, the sluice and the inn - that is the point and it is not for everyone. Fully exposed to wind. Do not walk onto the flats without a licensed guide.
