The Donauinsel parts the river Danube in a flowing part (River Danube) and the Neue Donau (new danube) which is formed by the Donauinsel and the eastern bank of the river.
There is no traffic on the island and the flat roads exclusively belong to countless cyclists, roller bladers and joggers. And you can swim in the Neue Donau with its 42km of beach. In the north and the south there are extensive nudist areas.
While the Donauinsel is very basic in most parts, in one place nightlife has established and some restaurants have opened. The Copa Cagrana (an allusion on Rio's "Copa Capana" and the name of the 22nd district of Vienna "Kagran") is humming with life and music day and night. It is only a stone's throw away from the Venue.
So don't forget to take your bathing clothes with you and refresh with a jump into Neue or Alte Donau after a day full of hot News and discussion at the conference.
