Vienna Sightseeing Tours ( www.Viennasightseeingtours.com ) run a variety of bus tours around the city and surrounding districts. Their standard city tour (daily 9.30am, 10.30am & 2.30pm; öS400/?29.07) takes around three and a half hours; pick up a leaflet at the tourist office or any hotel or pension. They also run a hop-on hop-off bus hourly (daily 9.30am-4.30pm), with running commentary in English and German; tickets cost öS250/?18.17 and are valid for two days. Alternatively, you can save yourself the relentless commentary by hopping on tram #1 or #2, which circumnavigate the Ringstrasse clockwise and anticlockwise respectively. Every Saturday (11.30am and 1.30pm) and Sunday (9.30am, 11.30am & 1.30pm) from early May to early October, you can also leap aboard a beautiful 1920s tram outside the Otto-Wagner-Pavillon on Karlsplatz and go on an hour-long tram tour , run by Wiener Linien ; tickets cost öS200/?14.54 and are available from Karlsplatz U-Bahn.
Even more appealing are the walking tours organized by Vienna's official tourist guides - you'll find details, such as whether the tours are in German or English, in the monthly Wiener Spaziergänge leaflet from the tourist office ( www.wienguide.at ). These cover a relatively small area in much greater detail, mixing historical facts with juicy anecdotes in the company of a local specialist. Subjects covered range from Jugendstil architecture to Jewish Vienna - the weekly Third Man tour takes you round the locations associated with the eponymous 1948 film (tel 774 8901). Tours cost around öS140/?10.17 and last between one and a half and two hours. Simply turn up at the meeting point specified.
