De Vlije is a marina and access point situated on the Steenbergse Vliet, a calm sheltered waterway in North Brabant, near the locks of Beneden Sas and the Dintelse Gorzen nature area.

It is one of three marinas along the Steenbergse Vliet that serve recreational boaters, offering mooring and entry to the 8-kilometer waterway where visitors can explore by small vessel at leisurely speeds.

The surrounding area is well suited to land-based recreation, with ample opportunities for hiking and cycling. There are no shops on site, but a pancake house and a casual dining café can be found within roughly 2 kilometers on foot.
