This 99-hectare (245-acre) park, in the 22nd District between the Danube Canal and the Alte Donau (Old Danube), was converted in 1964 from a garbage dump to a park with flowers, shrubs, and walks, as well as a bird sanctuary. You'll find a bee house, an aviary with native and exotic birds, a small-animal paddock, a horse-riding course, playgrounds, and games. An outstanding feature of the park is the Donauturm (Danube Tower), Donauturmstrasse 4 (tel. 01/2633-5720;, a 253m (830-ft.) tower with two rotating cafe-restaurants from which you have a panoramic view of Vienna. One restaurant is at the 161m (528-ft.) level; the other is at 171m (561 ft.). International specialties and Viennese cuisine are served in both. There's also a sightseeing terrace at 151m (495 ft.). Two express elevators take people up in the tower. It's open daily in summer from 10am to midnight and in winter from 10am to 10pm. The charge for the elevator is 5.50€ ($8.80) for adults and 4.10€ ($6.60) ages 10 to 18. Children 9 and under free.
