"Central Vienna lies not on the Danube proper, but on its curved canal whose banks were utterly neglected for decades. Today, in warm months, the canal's banks are a recreational paradise packed with fishermen, bike riders, dog walkers, and joggers. Entire beaches with imported sand and swimming pavilions host a city’s worth of bars and restaurants. Guests at the Strandbar Herrmann, in front of the elegant art nouveau Urania observatory, lounge on deck chairs, while the Badeschiff is a docked boat with a pool. On the left bank of the canal, Tel Aviv Beach bar hosts lively DJ parties on summer evenings. On Danube Island, which sits in the middle of the river, Copa Cagrana Beach has been popular for several decades."
