Travel by train to Rome for an enlightening walking tour of its most iconic attractions and then spend free time exploring further on your own. Although just under an hour, the train ride will be wonderfully scenic and offer an introductory look at the outskirts of Rome. Once you detrain at Saint Peter Station, you will follow the guide to landmarks such as Saint Peter’s Square, where you will behold its glorious namesake basilica from the outside. You will continue along Via della Conciliazione to Castelo St. Angelo, a fortress that was originally built in the 2nd century as the tomb for Roman emperor Hadrian. Free time will begin once you reach the elongated Piazza Navona, an exquisite expression of the Baroque period. If you wish, drop by its famed Fountain of the Four Rivers and the Fountain of Neptune. Or head straight for your choice of other nearby attractions such as the Pantheon.
