The Vatican museums + the Sistine Chapel is a must see! It’s a beautiful area with lots to see. Allow yourself at least 4 hours to tour.
Best time to go is super early in the morning! Avoid large crowds and get the best pictures. This is a quick attraction full of stunning views.
Another must see! Depending on your level of interest, you can spend anywhere from 1-4 hours here. If you book a tour, arrive plenty of time in advance to meet your group!
