Groningen, Friesland and North Drenthe is a freshwater diving region built around flooded peat lakes, where artificial reefs and wrecks provide the main structure. Sites such as t Veenmeer, Woudfennen, Middelbert and Gasselterveld offer shore-entry dives across a wide range of depths, from the very shallow to truly deep. The resident fish life is dominated by Pike, Common Perch, Carp and Pike Perch, all observation-backed regulars. Water is cold through winter and warms noticeably from late spring into summer, which shapes when most divers choose to visit.
