Swim on (not in!) the Danube. Floating on the bank of the Danube, between Schwedenplatz and Urania, this 28m-long lap pool has multiple decks with umbrella-shaded sun loungers and an open-air football pitch on the platform suspended above. It doubles as a bar at night; in winter the pool closes and the ship is a bar and restaurant only.
The hold of the ship contains a bowling alley and dance floor where DJs spin regularly. Tram to Julius-Raab-Platz.
