On a budget, Zaanse Schans Day-Trip still earns its price.
Free village; ~€5 train each way; mills €5–6 each
The easiest, most photogenic way to see real working windmills — a short, cheap train ride. But make the fit call honestly: this is the photogenic easy hit, an open-air museum overrun by coach tours and cheese-and-clog gift shops by midday. If what you actually want is to go inside a working mill without the crush, the Molen van Sloten on the city's western edge is uncrowded, guided, and authentic. Come to Zaanse Schans for the postcard skyline at opening; go to Sloten for the real thing.
