Vatican Route
A full Vatican day combining the fortress, the museums, the Sistine Chapel and St. Peter's Basilica. Start at Castel Sant'Angelo for views over the Tiber, then enter the Vatican Museums with a timed-entry ticket (almost always required — check the official Musei Vaticani site for availability and current opening days, since closures and Wednesday Papal Audiences affect schedules). Finish at St. Peter's, which is free but security lines can be long; the dome climb is a separate ticket.
