Very nice hiking trail directly at the Kalksee. But be careful. Danger of tripping. Rooty paths.

Very nice, I can't recommend just swimming here as there are trees in the water that can't be seen, which can lead to injuries when swimming over them due to sharp branches

The waterfront is a great place to take a walk. The brewery invites you to linger.

Beautiful place with a rest bench and a view of the Flakensee. On the opposite bank you can see the Flakensee Ost campsite and Woltersdorf in the area of the lock.
