Marina Numansdorp sits on the Hollands Diep near the point where that river splits into the Haringvliet and the Volkerak, directly opposite the historic town of Willemstad.

It lies about two hours by boat from the North Sea and is easily reached by road via the A29, roughly twenty minutes from Rotterdam.

The marina accommodates around 200 berths on wide floating pontoons with finger piers, suitable for vessels up to 25 meters with a draft of up to 3. 5 meters.

Both permanent berth holders and visitors moor comfortably, with individual power connections at each berth. The location makes it a practical base for exploring the Biesbosch, Zeeland, and a range of inland waterway routes.
