Probably the nicest place to hang out in Nowa Huta if you're having a socialist realism overdose, this reservoir and the surrounding park have served as a recreation ground for the district's hardworking residents since 1957. Unfortunately the area fell into disrepair in the 90s and never fully recovered, rendering swimming off-limits to all those who wish to avoid a nasty E. Coli/fecal bacteria infection.Clearly that's not everyone, as some intrepid swimmers can always be seen disregarding the 'no swimming' signs during the warm season. There's plenty of feces-free activities to engage in, however: from kayaking and paddle-boating (rentals available during the summer) to sunbathing and picnicking on the man-made beach to biking on the area's many trails. Fishing is encouraged (the reservoir is regularly re-stocked with carp & friends to appease the local fishermen), and there's a playground and a sports complex offering two swimming pools, a basketball court, and a tennis court. For a bit of an excursion visit the Jan Matejko Manor House and the next-door 17th-century wooden Church of St. John the Baptist hidden just behind the park. Have fun and don't drop your frisbee in the water.
