Oldambtmeer is a lake in the northeastern Netherlands, situated within the Blauwestad development near Groningen. The water is generally clean and conditions range from flat to choppy depending on wind. Swimmers are noted as a hazard on the water, which is worth keeping in mind when planning routes, particularly during the summer months of June, July, and August when beach use is at its peak and visitor numbers are highest.

Access to the lake is by car, with no significant walk required to reach the water's edge. The shoreline includes both grass and sand beach areas, though these tend to be small. The main access and amenity hub is the Havenkwartier Blauwestad, where cafes and restaurants are available. Accommodation options in the area include hotels and holiday homes, some situated on island settlements with direct water access.

The lake sits within a zone-regulated environment, so paddlers should be aware that designated zones govern use of the water. Visiting on weekdays or early in the morning during summer will generally mean fewer other water users. The extensive path network around the lake's perimeter also allows for quieter exploration away from the main access points. For those looking to extend a trip, the city of Groningen is the nearest major urban center.
