Three days is the right amount of time for a first trip to Rome. It covers the three things everyone comes for (the Colosseum and Forum, the Vatican, and the piazzas and fountains of the centre) without rushing, and almost all of it is on foot. The trick is to give each day one part of the city and to put the two timed tickets, the Colosseum and the Vatican Museums, on different mornings, since both are best at opening. Short on time? See the 1-day or 2-day plan.
Day 1 is ancient Rome: the Colosseum at 8.30am, the Palatine and the Forum, the Capitoline Museums, then sunset on the Aventine and dinner in Testaccio. Day 2 is the Vatican: the museums and the Sistine Chapel at 8am, pizza in Prati, St Peter's after lunch and Castel Sant'Angelo at dusk. Day 3 is the historic centre: the Spanish Steps, the Trevi Fountain, the Pantheon, Piazza Navona and Campo de' Fiori, then Trastevere and the Janiculum Hill. You'll walk 6 to 8 km a day.
Closing days decide the order. The Vatican Museums close on Sundays (except the last Sunday of the month) and Castel Sant'Angelo on Mondays, so Day 2 belongs on a Tuesday to Saturday (or, in 2026, the first Monday of the month, when the castle opens 2pm-8pm). Day 3 is best Tuesday to Saturday too, which leaves Day 1 for a Sunday or Monday. In winter (25 October to 28 February) the Colosseum and Forum stop admitting at 3.30pm. Prices are full adult prices at November 2026.
