Decide how to get to Pompeii. The city's location on the Italian peninsula makes it a perfect destination for a day trip, especially if you are staying in Rome. The distance between these two Italian cities is only 150 miles and will take about two hours of travel time on the Eurostar train. Naples, another Italian city, is only 17 miles and takes 45 minutes on the train. Booking your train tickets in advance is advised.
Decide how long you will stay in Pompeii. If staying overnight, book a hotel room. There are many hotels too choose from, and most offer good deals.
Visit the site and enjoy. You can purchase an all-day pass to explore Pompeii for around $12. A Pompeii guidebook will be of great help for providing background information about the city and what you see.
