De Groene Heuvels is a freshwater lake with clear water and objects.
De Groene Heuvels is a freshwater shore dive near Ewijk with an easy sandy-beach entry and a mix of submerged objects, including wrecks, pipes, and a traffic sign. The lake has a slow slope and enough structure to keep beginner divers interested without becoming technical, so it works well for training, relaxed exploring, and night dives when allowed. Divers come here for calm inland conditions and freshwater fish rather than coral or surf.
