The Feisnecksee , also called Feisneck , is located on the southeastern outskirts of Waren in the northwest of the Müritz National Park in the Mecklenburg Lake District in southeast Mecklenburg. The lake is connected to the north-west of the Binnenmüritz by a very narrow, shallow ditch that cannot be navigated by boats. The road here leads over a small bridge that can only be used in one lane by large vehicles. The land bridge is about 150 meters wide at this point. The lake is a typical glacial channel lake and divided into a north and a south basin by a constriction and the larger castle wall island above . It is approximately 3,100 meters long and 600 meters wide. The Damerow district of Waren is located near the southern part. The lakeshore is completely surrounded by a belt of reeds and wooded in the south. There is a swimming area on the northern part of the lake. Fishing is only permitted with a special permit, as the lake is located in the national park.
