You leave the entrance to Fort Sint-Marie 100 meters further on the left and you turn right onto the 'dijk' (Kwarikweg). In front of you is the sprayed on (northern) part of the Groot Rietveld. Follow the asphalt road to the right to view the entire west side of the area.

The site is not big and easy accessible. No roads on the site itself but along the edges, where you can park and watch birds over the reedbeds.
