Naples has a public transport network consisting of buses, trolleys and a subway, which is a bit complicated to use but preferable to taking on the city's notorious traffic jams in a hired car or taxi. Tickets for all forms of transport are uniform, and can be obtained at stations and news kiosks. The city's ANM buses are fairly frequent, most departing from the Piazza Garibaldi. The 'Metropolitana' metro line serves downtown (where most sights are located) and is generally the most useful for sightseeing. Funicular railways run up the Vomero from stations at Piazza Montesanto, Amadeo and Augusto. There are taxi ranks in most piazzas, but using a taxi can prove expensive because of traffic congestion. It is possible, and pleasurable, to walk around the historic centre of Naples where many of the main attractions are located, but some of the worthwhile sights, like the Fontanelle Cemetery, take tourists into potentially dangerous areas where it may not be a good idea to walk alone. Travellers should ensure they have a detailed map to help them navigate the streets of Naples, and ask at their hotel for advice on which areas should be avoided.
