Zurich is easy to navigate, and a modern, user-friendly network of trams and buses covers the city daily from 5.30am to midnight, with a more limited night service on weekends. Transport works on a zone system, and tickets are valid for an hour. Tickets are transferable but must be bought before boarding; they are also valid on some boats and local city trains. The most useful travel pass is the Tageskarte (one day ticket) that allows travel on all buses and trams for 24 hours; however, tourists should use the ZurichCARD which entitles the holder to unlimited free use of public transport. Travelling by taxi is expensive even by Swiss standards, but they are safe and convenient and can be hailed on the street, found at taxi ranks or ordered by phone. Getting around by car is not recommended due to congestion and expensive or scarce parking. From mid-April to mid-October, bicycles can be hired free from various stations. Walking is also a good option in the city centre.
