Großer Seddiner See

The Great Seddiner See, often simply Seddiner See, formerly Seddinsee, is 218 hectares after Blankensee (280 hectares) the second largest lake in the Nuthe-Nieplitz Nature Park. It has an average depth of 3 and a maximum depth of 7.2 meters. Its edge zones are largely reeded. There are several sandy beaches on the lake, the largest in Kähnsdorf. Motor boats are prohibited on this lake.

Separated by the B2 federal highway, the Kleiner Seddiner See (around 4.4 hectares) adjoins the long stretch of water at the western end. A narrow strip of land on the south-east bank also separates the Kähnsdorfer See (around 26 hectares) from the Großer Seddiner See.

The shallow lakes were created in the Brandenburg stage of the Vistula glaciation around 20,000 years ago.

An approximately 10-kilometer circular hiking trail around the Seddin Lakes is part of the 66 Lakes Regional Park Route, a hiking trail around Berlin.

Beautiful, almost natural hiking trail on the bank that requires a certain degree of step resistance, the roots of the trees are quite treacherous. Especially when it's damp!

Very clean water and several swimming spots are not so busy. Despite the warm weather.
