Jachthaven van Oversteeg is a marina located in the northern part of the Biesbosch, serving as a popular launch point for kayak, canoe, and motorboat excursions into this expansive freshwater wetland.

Paddlers setting out from here can access the Jantjesplaat, one of the Biesbosch's many polders and among its most recently restored wetland areas.

The marina sits at the start of a roughly 30-minute paddle to the Jantjesplaat, where a pole campsite allows overnight stays by reservation.

The surrounding creeks and the canoe area known as het Biezengors offer winding waterways through true wilderness, with a notably high chance of spotting beavers.

The Jantjesplaat is also accessible on foot via an orange-marked hiking trail managed by Staatsbosbeheer.
