Leisurely Hike and Swim at Liepnitzsee

we will take the SBahn at 12.06 (Gesundbrunnen platform 4) to Karow and then RB27 at 12.27to Wandlitzsee. from there we will do a leisurely hike around Liepnitzsee. Its about 15km in total and there are two good places to stop and swim. we will end up at the Biergarten in Wandlitzsee and aim to catch the 18.30 train home.
Please bring a packed lunch and water. The walk is relatively well shaded through the woodland but you may want to bring sun cream or mosquito spray. please also wear good walking shoes.
The hike will be relaxed and at a leisurely pace.
