By Public Transportation On Land
It is fairly difficult to get a clear picture of the public transportation system in Naples, since different lines are operated by different companies. Nonetheless, one can buy a daily pass for three Euro valid on all vehicles. With an ⬠1,20 ticket, instead, you can travel for 90 minutes on as many lines as you want Bus, subway, funicolare.
Metropolitana di Napoli
(http://www.metro.na.it). There are six lines of underground subway in Naples. They are generally safer than the other public transport, because they are always monitored by cameras and security officers. But the subway does not run frequently, so do not rely on it if you are in a hurry. The most important:Linea 1, built recently, connects the city center to the hill quarters, like Vomero and the hospitals area. Avoid passing through Piscinola and Secondigliano as those areas can be very dodgy and dangerous.Linea 2, much older, connects the three main train stations to Pozzuoli. The tracks are shared with the ordinary railwayLinea 6, a new light subway connecting Fuorigrotta to Mergellina.
Funicolare
(http://www.metro.na.it). The subway company also operates four cable cars: three of them connect the city center to Vomero, the last connects Mergellina to Posillipo.Trams
(http://www.anm.it). ANM operates two tram lines 1 and 4, of which one goes along the shore of Santa Lucia - Castelnuovo - Garibaldi Central Station.Buses
(http://www.anm.it). ANM also operated all bus lines within Naples, most of which are circular. Naples suffers from a serious problem of traffic jam and usually buses are overcrowded, so if you can unless in the evening or on the weekend try to avoid them. Another point to note is that unlike in Rome, tickets are not sold on buses. The bus company assigns staff to check if a passenger has a ticket. The staff members are notorious for targeting at tourists who are unfamiliar with the ticket-selling system. Once they see the tourists get into a bus, they will ask to see a ticket. No matter how much you explain, they will insist on getting your passport first and then requiring you to pay a penalty of 41.2 Euro. If you do not pay, they will threaten to call the police. Again, if you can, try to avoid taking a bus.There are three different regional train services that operate in Naples and the surrounding areas. They are listed here:
Circumvesuviana
The Circumvesuviana railway operates from the lower level of the main train station at Piazza Garibaldi and has various routes that service the local Naples area. One route goes from Naples to Sorrento with several stops in between, including Pompei Scavi Pompeii and Ercolano Herculaneum. A second route travels around Vesuvius. Other routes go to Acerra and Nola-Baiano. The Circumvesuviana website (http://www.vesuviana.it/) has more information on timings, routes and cost of tickets.Cumana
This railline that operates from Montesanto in Naples and follows the coastline for approximately 20 km before ending in Torregaveta Bacoli. The Cumana runs the urban centres of Montesanto, Fuorigrotta, Bagnoli, Pozzuoli, Arco Felice, Baia, Fusaro before reaching Torregaveta.Circumflegrea
This railline also starts in Montesanto and ends in Torregaveta. However, it runs along the western edge of Naples through the districts Soccavo, Pianurat, Quarto Flegreo, Licola and Cuma. It also approximately seven kilometers longer than the Cumana. because the Cumana and Circumflegra start and end in the same places one can quickly transfer from one train to the other. Both services are owned and operated by the same company and more information can be found at the S.E.P.S.A website (http://www.sepsa.it/html/...).Regional Trains
In Addition to the aforementioned trains, Trenitalia operates regional trains from Naples to Salerno.
By Ferry/Hydrofoil
There are several ferry/hydrofoil services that connect Naples and local ports/islands. Ferry and hydrofoil services leave from either Molo Beverello, Mergellina or Pozzuoli. Some then of them are listed here:
Metro del Mare
(http://www.metrodelmare.c...) has several lines that connect Naples and Sapri; Bacoli and Salerno and Sorrento; Monti di Procida and Salerno; and, Amalfi and Sapri. Besides the main stops the ferry service also connects many smaller communities. The Metro di Mare webpage has schedules, timetables and location of ticket counters.L.N.G.
(http://www.navlib.it/index.asp) has a hydrofoil service that connects Naples with the island of Capri, along with Sorrento, Positano and Amalfi. Schedules and timings can be found on its website.AliLauro
(http://www.alilauro.it) has a hydrofoil service that connects Naples with the islands of Ponza, Ventotene, Prochida, Ischia, Capri and Eolie, and the towns of Formia, Castellamare, Sorrento, Positano, Amalfi and Salerno. Alilauro operates from both the Molo Beverello and Mergelina.L.N.P.
(http://www.consorziolmp.it) operates both hydrofoil and boats lines. It connects Naples with Sorrento and has other lines connecting Capri, Sorrento, Castellamare, Salerno, AMalfi and Positano. Schedule and timings can be downloaded from the L.N.P. website.Just a note: the ferries to Capri can be over rough seas. Get on a ferry with an outside deck, take gravol or something similar before you sail. Nothing like being on a boat for 70 min surrounded by people who are vomiting to get your day off to a bad start.
