Donauinsel, Vienna, Austria

The island has these insanely powerful sprinklers placed along it that drenches anything within a semicircular area in front of it.

View from the - for lack of a better word - battery.

Formation swimming.

The island has great bicycle and rollerblade paths. While some paths use cobblestones (as can be seen on this picture and the next), most have a very smooth asphalt surface.

View of Vienna International Center.

Sunset behind the Millennium Tower as seen from the Copa Cagrana restaurant area.
