Donaupark, or Danube Park, is huge - 2,600,000 square feet (800,000 square metres). Located on the north bank of the impressive Danube River, it even has beaches for the summer months. There is a stage with live entertainment, a mini train to ride, a giant chess board, tennis courts, a skater park, bike paths and a small zoo!
Until 1945 it was a military firing range, then it was used for landfill. Finally it became a park, originally for the Vienna International Flower Show of 1964. At this time, Vienna's tallest structure, the Danube Tower, was also built in the park. It's 826 ft (252 m) high and has a revolving restaurant and viewing platforms. In 1983, Pope John Paul II celebrated a mass at the base of the tower. And of course, people bungee jump from the tower.
Catch the U1 metro to the Alte Donau stop. The park is only 2.5 miles (4 km) from the city centre and easy to reach by road also.
