Subject: Naples for Arthur
I am pretty familiar with public transportation. Within the city there's the Metro connecting the Central Station (Piazza Garibaldi) with the other stations (Mergellina, Campi Flegrei) and with Pozzuoli (volcanic area, I recommend it!). On the other side, the Circumvesuviana train also departs from Piazza Garibaldi and goes to Pompei, Hercolaneum, Sorrento. Furthermore, there are buses going all around the city. The only recommendation is to be careful, since the metro and the buses can be overcrowded and there are pickpockets. Traffic can be heavy, especially on rush hours, that's why (when possible) train or metro are better than buses.
