The Blankenburg Lake, known to divers as “Blanki“, is a 21.5 hectare large and 16m deep rectangular quarry lake. Excavated for highway construction, the lake is now known as a fishing, diving and swimming lake. One of the entrances can be reached on the north bank from the parking lot via a trail.

The Banter See is a large rectangular 22m deep sailing, diving, surfing and swimming lake. Separated from the North Sea by the Grodendamm embankment, the lake still has a slight salt content today. Ruins, the bow of a harbor barge and blown-up quays can be found on site due to the war.

At the entrance 4B is a slightly sloping shore. At about 8m depth you will find the first car wrecks. If you dive after about 5 minutes over a plateau, you reach a break-off edge, which reaches to approx. 35m depth. Right hand along the edge is the wreck Hemmoor at about 17m.

Just perfect for everything :-) Diving, camping, eating, barbecuing, clear views, good visibility, dogs allowed, playground and much more... we love it there.

The Chalk Lake has an area of 33 hectares and is 60 meters deep. During longer periods of good weather, visibility can rise up to 25 meters, thus creating an optimal dive location.

Kreide-See is a well known and popular diving lake. In former times chalk was mined here. The roads, the vibrator, trucks, conveyor belts, and some machines that were needed for the mining can still be visited underwater.

The chalk lake, artificially created by opencast mining, has an area of 33 hectares and a maximum depth of 60 meters. Visibility of up to 25 meters is possible under favorable conditions (longer dry periods). Lots of abandoned mining gear and items sunk especially for divers.

Entry can be reached via the large meadow in the direction of the jetty and takes you directly to the platform at 5 meters. Very good for skill exercises.

From the entrance on the left, a steep wall worth seeing goes down to the bottom of the lake at approx. 55m, a little further on, from 35m downwards, scrawny little trees stand close together, the so-called "male forest". To the right of the entrance is the former fish farm, since 2021 diving is allowed.

A very beautiful and Hamburg’s only diving site. From the DUC entrance (Warwischer Hinterdeich 55), there is a small parkour at depths of 5-13m. Various good entrances around the lake. Please do not park on private property.
