Yes, you must pay an entrance fee to visit the Pompeii Archaeological Park, and as of January 12, 2026, the pricing structure has been updated to manage the high volume of visitors. A standard "Pompeii Express" ticket, which grants access only to the ancient city itself, costs €20. If you wish to see the suburban villas, including the famous Villa of the Mysteries and Villa Diomedes, you must purchase the "Pompeii+" ticket for €25. For travelers wanting a multi-day experience, a 3-day pass covering all sites in the park (including Oplontis and Boscoreale) is available for €30. There is a reduced rate of only €2 for European Union citizens aged 18 to 25. Admission remains free for everyone on the first Sunday of the month, but keep in mind that a daily limit of 20,000 visitors has been introduced to prevent overcrowding. It is highly recommended to book your tickets online in advance to secure your entry time and avoid the long queues at the Porta Marina entrance.
