Recreatiepark De Oude Maas is a campground and marina situated on the banks of the Oude Maas in Barendrecht, South Holland.

The park offers a variety of pitches — including waterfront motorhome spots, dike-top positions with open river views, and a greener inland camping field — along with mobile homes and seasonal pitches.

Barge traffic on the Oude Maas is a constant backdrop, and the setting draws visitors who enjoy watching river life and wildlife. Facilities include a toilet block with hot showers, a launderette, a playground, bicycle hire, fishing, and WiFi.

A marina with a boat ramp is also on site. The park serves as a convenient base for day trips to Rotterdam, Dordrecht, and Kinderdijk, all reachable by bicycle or public transport from nearby Barendrecht.

The small town of Heerjansdam, with shops, bars, and restaurants, lies within about 1,500 m.
