Hannover has an excellent public transportation network, made up of buses, trams, and a subway. Day tickets are available and are good value for travellers planning to take more than two trips. The Hannover Card, issued by the tourist office, provides free rides on public transportation as well as discounts for museums and other attractions. Taxis are expensive, but large vehicles for seven to nine people are available by phone and can be cost effective for groups. Like many cities in Europe, Hannover is a bicycle and pedestrian-friendly metropolis, with bike lanes on many roads and a large pedestrianised area in the city centre.
