Upon entering the museum’s entrance, you need to pass through security check-in, go to the left, to one of the windows with the word CASSA on it: that is the place where the Vatican employees will scan your voucher and exchange it for your tickets. You can find the ticket windows upstairs as well. Having scanned your ticket and passed the turnstiles, you will continue upstairs. There are an escalator, spiral stairs and an elevator (reserved for wheelchair access and strollers). After the escalator, there is another flight of stairs. Continue straight out for a nice panorama view and head right after the stairs to enter the pinecone courtyard.
