• Meadows by the S-Bahn: the Paul-Ernst-Park lawns run from Schlachtensee station down to the south shore and fill fast on hot days; more meadows sit on the northeast shore
• A shaded path all the way around, popular with walkers and joggers, so a lap fits easily between swims
• Alte Fischerhütte on the east bank, a historic inn with a beer garden, a kids' playground and boat rental

Schlachtensee is a long, narrow lake at the edge of the Grunewald forest, known for its clear water. Kids wade in from grassy meadows and small sandy patches along the shore, while stand-up paddlers glide past. A path runs all the way around under the trees.

The Alte Fischerhütte on the east bank is a historic inn with a beer garden, a playground and boats for rent.
