Marina Numansdorp sits on the freshwater Hollands Diep, directly opposite the historic town of Willemstad.

It lies roughly two hours by boat from the North Sea and about twenty minutes by road from Rotterdam via the A29, making it a convenient gateway for both coastal and inland cruising.

The marina accommodates vessels of varying sizes on floating docks with a depth of 3 meters or more at mean low water. The location serves as a practical base for exploring the Biesbosch and the waterways of Zeeland.

Visitor berths and catamaran berths are available, and the marina includes a port office with a terrace, bike rental, and Wi-Fi.
