Rome's activities (apart from the mandatory sightseeing) usually involve nothing more strenuous than eating, drinking and listening to good music. Conceivably you could work up a sweat running up and down the Spanish Steps; though everyone will get excited thinking you're chasing a pickpocket.
Roman HolidayTry packing this little sampler into three days: start with the obvious choices of the Sistine Chapel, the Vatican Museums and St Peter's Basilica. Catch your breath over a leisurely lunch around Piazza Navona. Pass by the Pantheon before exploring the Roman Forum and Colosseum in the afternoon. Make a night of it in lively and atmospheric Trastevere.Spend a morning at the market in Campo dé Fiori and the Capitoline Museums. Let the ancient wonders at Palazzo Massimo alle Terme captivate you, before plumbing Rome's multilayered history at the San Clemente Basilica. Wander through Villa Borghese and visit the magnificent, and hopefully prebooked, Galleria Borghese. Or get some retail action at the swish designer stores around Via Condotti. Naturally, spend your evenings on a passeggiata(stroll) - with gelato - from Piazza di Spagna to the Trevi Fountain. Check out 'Il Campo' for fun after dark, or stay out far later than you should in Testaccio.
