This large body of water, linking 3 nearby rivers: the Vistula, Narew and Wkra, is the summer playground of Varsovians and those living nearby, who wish to get away from the city and enjoy the beaches, bars and water sports. And no wonder, as it's only 20km north-west of Warsaw. To say this place is a place of relaxation may be slightly overstated as when the good weather hits, it's quite a tight squeeze for space! This isn't always the case, and people can't be blamed for wishing to throw themselves in the water when temperatures go above 30ºC! Primarily during Spring-Autumn, the lake is full of yachts and other water faring contraptions, but come winter, the reservoir traffic turns to ice-skating (if you feel brave enough!). Getting there can be done easily using the ‘Zefir’ ferry (Fri, Sat & Sun until end of Aug and then Sat & Sun until 15 Sep) at 09:00 in front of the Royal Castle at ‘Podzamcze’ or 09:15 from the Żeran Canal (summer only, each Sat & Sun until 15 September) near bus stop Cementownia 02. A one way journey costs 36zł normal fare, and 18zł reduced. The ferry will take you to the northern part of the reservoir to the town of Serock where you have two hours before the return journey. Alternatively, more regularly, take bus 735 from Metro Marymont bus stop 15, which will take you to the southern part of the reservoir to stop Zegrze Południe and requires a zone 2 ticket. If the busy beaches are not your thing, the surrounding area has plenty of quiet tourist trails to enjoy.
