You can book the free Vatican Museums through the official website, selecting the dates and times available for the free visits, which are usually held on the last Sunday of the month. It is important to book in advance, as places are limited.
To visit the Vatican Museums without paying, the best solution is to take advantage of the free openings that take place on the last Sunday of each month. On these occasions, admission is free, but you must book your place online on the official Vatican Museums website. Booking is essential, as the number of visitors is limited and queues can be long. When booking, you will need to select the date and time of your visit, and you will be given an e-ticket to present at the entrance.
Furthermore, it is useful to know that the Vatican Museums also offer other opportunities for free admission, such as for residents of Rome or young people under a certain age on certain days. I advise you to check the official website regularly for any updates or special events. Remember that even if admission is free, it is always good to respect the museum's rules and guidelines to ensure a pleasant and safe experience for everyone.
