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. Although the area fell into disrepair in the 90s, it has been invested in heavily and modernised in recent years, turning it into a bona fide family attraction ideal for picnicking and enjoying the sunshine. 2020 saw the addition of an outdoor stage, pier, graduation tower, beach chairs and an artificial beach, and you can even go swimming if you're brave. Food trucks, coffee and ice cream are all on hand in summer, as well as kayak rentals and paddle boats. Fishing is encouraged (the reservoir is regularly re-stocked to appease the local fishermen), and there are also two playgrounds and a sports complex (offering two swimming pools, a basketball court, and a tennis court), plus plenty of cycling trails.
For further adventure, you can find a trail behind the playground quickly leading to the Jan Matejko Manor House and the next-door 17th-century wooden Church of St. John the Baptist; both sites are seldom open, but make for an interesting glimpse at the village vibes Nowa Huta's colossal concrete corridors wiped out.
