The Metro Valencia has five lines that run to major points within the city, including a tramway to the beach. The system runs from 5.30am to midnight. The city bus system has fairly comprehensive service within Valencia, running from 4.30am to 10.30pm, with additional night buses from 10.30pm to 2am (3.30am on Fridays).The Valencia Tourist Card offers unlimited use of the bus and metro for one to three days, and can be purchased at hotels and tourist offices. Many people find that most of the city centre can be explored on foot, unless they plan to go to the beach. Taxis are the most convenient way to get around at night; they can be hailed on the street, found at taxi ranks, or phoned. Fares are metered, and rates should be clearly displayed.
