Best Time to Visit The Holy See
Last but not least, the thing about Holy See you should know is the best time to visit. The best time to visit the Holy See is from May to October, not including August, when the most popular galleries in museums, such as the Raphael Halls and the Sistine Chapel, are open to a limited number of visitors who pre-book tickets. 8:00 AM is the best time to get there.
Every day, up to 30,000 people who want to mark the Vatican on the map as an already conquered country visit St. Peter's Basilica, the epic center of Renaissance Catholicism, as well as the 54 galleries of the neighboring Vatican museums, filled with masterpieces. Since they've all read the same guidebooks, most of them arrive early in the morning to do the galleries first. Hence the queues are winding around the block. Therefore, you can postpone your visit to the basilica until noon.
