Just 5km south-east of Kraków’s rynek is Zalew Bagry – a large reservoir and probably the most popular destination for water activities within city limits. There are three “wild” beaches and a life-guarded bathing area in water checked regularly and certified clean. There are two marinas and a children’s playground and you can hire kayaks, canoes, pedalos and sailing boats.
Get there on a No 20 tram to Rzebika, then a 10-15 minute walk.
Kryspinów Lagoon is a little farther out – about 12km west, take a No 1, 2 or 6 tram to the terminus at the Salwator roundabout, then a 209 bus to Kryspinów Zalew or a 269 to Budzyń.
Actually two lakes, and formed on the site of a sand mine, what you’ll find is not even IN Kryspinów (they’re actually in the neighbouring village of Budzyń) but it IS said to be the most popular destination of Krakowians on a nice summer day. For sure, it gets extremely busy in hot, sunny weekends.
The main beaches have lifeguards and you can picnic or barbeque on the sands or the grass. There is beach volleyball, a basketball court, and a climbing park (www.parklin.pl). There is also a water slide that is open on hot days. Rental companies by the water offer paddle boats and sail boats. In the vicinity is a wake park and a windsurfing school. For adults, there is quad biking on a large dirt track, another area with a track for kid size ATV’s, as well as Zorbing for both adults and kids, and a trampoline on sunny days at Dreamlandia (www.dreamlandia.pl). And a nudist beach.
For those without their own supplies, there are many places to eat around the lakes. There are also toilets.
