The Möhnesee (Möhne Reservoir) is the Sauerland's largest lake and a major recreation destination. Created by the famous Möhne Dam (infamous for the WWII Dambusters raid), the lake is surrounded by forests and offers excellent sailing, motor boating, and swimming at designated beaches.
Möhnesee is the largest lake in the Sauerland, a reservoir formed by the Möhne Dam, best known internationally as the target of the 1943 Dambusters raid and today one of North Rhine-Westphalia's most popular outdoor destinations. The shoreline is mostly grassy banks and gravel paths rather than fine sand, with several designated swimming areas set apart from the main sailing and motorboat channels that run the length of the lake. Because of its scale, conditions vary by location: the areas near the dam and the main villages of Delecke, Körbecke, and Günne see the heaviest traffic from sailing dinghies, motorboats, and pleasure cruisers, while quieter coves further along the shore stay calmer and are better suited to swimming and sunbathing. Lakeside restaurants and beer gardens cluster around the main villages, and an information centre near the dam covers the reservoir's history and engineering. Cycling paths follow much of the roughly 40-kilometre shoreline, making a full circuit a popular full-day outing, while shorter walks are easy to combine with a swim. Sailing clubs and motorboat hire operators are concentrated near Körbecke and Delecke, and fishing is permitted in designated stretches with a local permit. Möhnesee is about 45 minutes from Dortmund by car or a combination of train and bus, and parking is available at several points around the shore, though the villages fill up quickly on sunny weekends between June and August. Given its size, visitors seeking a quieter swim generally do better away from the dam and main village fronts, while those wanting restaurants, boat hire, and a lively atmosphere should head for Delecke or Körbecke.
