One hour each.

The gardens are just about 200m from the palace outside the town walls. They are very large but as we had booked an inclusive deal we got driven around the gardens in open sided mini buses. There is parking outside the town walls but not a lot as it is a one way system and the buses have to turn around just outside the main gate. Personally its easier to go with the tour we used the Vatican website and went with them direct.

Not sure - hard to tell from their website We went on on our own taking a train from Termini Station at around 12:00 - arriving at 13:00 then walked up the hill and bought a ticket at the gate - it's simple enough to be honest.......................
