swimming
Unfortunately you can’t go for swimming in the Grundlossee. Since the Langhagensee lies directly behind the Grundlossee you can find some "wild” swimming places here and also the beach of the community.
Here you can swim and relax. The jetty, built by the community Sewekow, offers a jump into the cool wet to the courageous.
You can reach the swimming place in 5 minutes.
