At Vatican City, visit St. Peter's Basilica, climb the dome, and tour the Vatican Museums. Spend the early evening shopping and enjoying the local passeggiata by doing what I call the "Dolce Vita Stroll" along Via del Corso (start at Piazza del Popolo and end up at Piazza Venezia for great sunset views).
Do you book a tour for the first part? Looks like there are tours that cover both… or better to go through official websites? If a double tour, which operators are recommended?
Thanks!!
