As soon as it gets hot in Warsaw, the riverfront bursts to life not only with wildlife, but with locals aiming to chill out on some sand. You wouldn't think it, but the city has some top class public beaches, right within city limits. That's also the cool thing about the city, the banks on each side of the river are completely different - the left bank Vistula Boulevards reflect a sanitised version of a typical city riverfront, whereas the right-bank is wilder, more rugged and looks more like a nature reserve. Along both sides of the river, you will find some great public beaches to chill out in if the tourist crowds get a bit too much to handle...
