After you fortify yourself with a good breakfast and wear a pair of sturdy walking shoes, start this walk from the Vatican Bed and Breakfast Rome to see the great St. Peter's Basilica followed by the dazzling treasures of the Vatican Museums, it would take at least 3 hours, also considering you need usually 1 hour beeing on line for the Vatican museums. In the afternoon you can also take in some of the wonder of the Castel Sant'Angelo, that mausoleum-turned-fortress.

1. Piazza San Pietro
You can even arrive here early -- perhaps 7:30am -- for a 30-minute walk around before the basilica opens. This is one of the world's most famous squares, designed by Bernini in the 1630s. It is the gateway to the largest church in the world.

2. Basilica di San Pietro (St. Peter's Basilica )
When the church doors open, rush in. Once here, it's hard to do anything but gasp at the size and the magnificence. The cupola was designed by Michelangelo, and the artist also created the most famous Pietà in the world. There is so much to see here that you should allow at least 1 1/2 hours. With what time remains in the morning, explore the:

3. Musei Vaticani (the Vatican Museums ) & the Cappella Sistina (Sistine Chapel)
These museums are the richest in the world, and will take up the better part of your day -- allow at least 3 hours for a cursory visit. They are well worth your valuable time. There are so many museums here in addition to Michelangelo's Sistine Chapel, plus several papal apartments. A full day is actually needed, but you can cut your visit to a fraction of that by previewing our attraction reviews and deciding in advance what you want to see. If you took our advice and had a large breakfast, you can hold out for a late lunch.

4. Castel Sant'Angelo
Built in A.D. 135, this imposing fortress was originally constructed as a mausoleum for the Emperor Hadrian and his family. The entrance is across from the Ponte Sant Angelo, the bridge across the Tiber. Inside, you can visit the Popes' Apartments and from the terraces enjoy one of the great panoramic views in all of Rome. Allow at least 30 minutes (more if you can spare it) to look around.
