Jachthaven De Leeuwenbrug operates both the Noorderhaven and Zuiderhaven in the heart of Harlingen, one of the oldest cities in the Netherlands. Together the two harbours offer around 100 visitor berths and 92 permanent berths.

The Noorderhaven accommodates vessels with a draft of up to 2. 20 m, while the Zuiderhaven is reserved for larger, deeper-draft boats. Both harbours are tidal. When the water level reaches NAP +1.

10 m, high-water gates close — typically from about one hour before to one hour after high tide, though onshore winds can extend the closure. During that window, entry and departure are not possible.

The marina sits within easy walking distance of Harlingen's shops, restaurants, and terraces. Access from seaward is via the Van Harinxmakanaal; after passing through the Tsjerk Hiddesluizen lock, turn immediately to starboard when arriving from the sea.
