Gemeentehaven Harderwijk is a municipal harbor on the Wolderwijd, accessible via a dedicated entrance channel. The harbor is divided into three distinct basins: the Stadshaven, the Vissershaven, and the Strandhaven.

The Vissershaven accommodates around 130 visiting boats and features low pontoons suited to the old tidal harbor. Day visitors with small open boats are welcome in the Strandhaven, though overnight stays there are not permitted.

The harbor offers standard facilities including shore power, drinking water, wastewater disposal, showers, toilets, and a laundry. Maximum vessel dimensions are 20 m in length, 9. 5 m in beam, and 2 m draft.

From the berth, the historic town center, the Boulevard, and the Dolfinarium are all within easy walking distance.
