Jachthaven Van Oversteeg is a marina and boat-rental facility situated on the Gat van den Hardenhoek in the Biesbosch, near Werkendam in North Brabant.

It serves as a popular launching point for exploring this expansive tidal freshwater wetland, where visitors can rent canoes, electric motor sloops, or stand-up paddleboards.

Staff provide orientation before departure, and a map of sailing routes is available in the on-site café. The marina offers guided route suggestions that wind through creeks, wide ditches, and willow-lined banks.

Paddlers should be aware that tidal fluctuations in the Biesbosch can create shallow areas in places.
