The train is the easiest mode of transportation when it comes to traveling from Naples to Pompeii. You’ll want to look for the Circumvesuviana train, as this is the one that will take you right to Pompeii.  The train is similar to a commuter train—it can get hot and crowded, so be prepared to stand if needed. The Napoli Centrale is the main train station in Naples. You can find tickets at the ticket office next to the platform or at newspaper and tobacco shops in the station. Since the train runs every 30 minutes, you don’t need to purchase the tickets in advance—you can just do it once you get to the train station. You'll be purchasing a one-way ticket. While you can just stay in Napoli Centrale station to ride the train, it’s going to be super crowded and you may not get a seat. By walking to Piazza Nolana station where all trains depart, you’ll be much more likely to get the seats you need. Piazza Nolana is only an 8-minute walk from Napoli Centrale. You’ll see signs in the train station leading you to the Circumvesuviana line. Once you board the train and ride for about 35 minutes, you’ll arrive at your stop—”Pompei Scavi/Villa dei Misteri.” Exit the train, making sure that you don’t leave any of your belongings behind.  The train platform will be downstairs. Pickpocketing is often a problem on the train, so keep an eye on your belongings at all times. If you brought luggage with you, store it in the luggage storage facility in the Pompeii Scavi station. You’re not allowed to bring luggage onto the Pompeii site. Once you leave Pompeii Scavi station, you’ll turn right to start heading towards the site. After about a 5-minute walk, you’ll reach the entrance to Pompeii where you can purchase tickets. If necessary, you can look at a map or ask a local to find out if you’re going the right way.
