The HVV (194 49; www.hvv.de) operates buses, ferries, U-Bahn and S-Bahn, and has several offices, including at the Hauptbahnhof and at Jungfernstieg station.
The city is divided into zones. The Nahbe-reich (central area) covers the city centre, roughly between St Pauli and the Hauptbahnhof. The Grossbereich (Greater Hamburg area) covers the city centre plus outlying communities like Blankenese, and is the ticket you’ll most commonly need. The Gesamtbereich covers the entire Hamburg State.
S-/U-Bahn tickets must be purchased from machines at station entrances; bus tickets are available from the driver. Only single tickets (€1.55) are available in the Nahbereich.
Driving around Hamburg is easy. Major thoroughfares cutting across town in all directions are well signposted. Parking is expensive, however, especially in the city centre.
All major car-hire agencies have branches in Hamburg. Budget (01805-244 388) and Europcar (01805-5000) are both at the train station and airport. The city office of Hertz (01805-333 535; Kirchenallee 34-36) is just opposite the Hauptbahnhof. Local agencies include Star Car (468 8300; Jenfelder Alle 2-4), with cars available from around €30 per day or €50 per weekend.
Taxis can be found at the Hauptbahnhof, Dammtor and Altona, and at some larger S-Bahn and U-Bahn stations. You can book one by calling 441 011 or 666 666.
