Lust for a jump into the cool water? Then the Feringasee in Unterföhring northeast of Munich is the perfect place. Around the bathing lake leads an idyllic gravel path without many meters of altitude, on which a lake round is 2 kilometers long. With detours to other paths, you can extend your lap length but arbitrarily.
After that, either a beer garden invites you to relax or beach volleyball courts to even more sports. Or you just relax on the lakeshore and go for a swim.
As a starting point, the S-Bahn station Johanneskirchen offers itself, from which it goes over meadows and fields to the Feringasee.
