This is a nice place for a walk or a jog around the lake to stretch your legs. It's an easy walk…read morewith very slight uphill/downhill, and there are plenty of families walking or biking around as well. You have the option of taking a tiny motorboat across the lake (for a fee, I assume - I myself have never taken it). Because this lake is mostly used for rowing/rowing practice, it's closed to swimming, but there's a "Seebad" on one end of the lake where you can pay to go swim. There's also a small playground for kids on one side of the lake.
