3 Days in Rome 2026: The Colosseum, the Vatican and the Old Centre, Day by Day

This is the plan I'd give a friend. It follows the route I took in Rome in late November 2025, put in a better order, with the official prices, hours and rules as published in October 2026. Where I describe my own visit, I say so.

Before you go: book two things

1. The Colosseum. Tickets go on sale 30 days ahead on ticketing.colosseo.it. They carry your name and an entry time, and if you're late, you lose the Colosseum entry. The Colosseum guide compares the tickets.
2. The Vatican Museums. Book at tickets.museivaticani.va as soon as you know your dates. In mid-October 2026, every open day for the next three weeks had sold out. The Vatican guide has the rules.

Then pick your days:

• The Vatican: Monday to Saturday. The Museums close on Sundays, except the last Sunday of the month, when entry is free. The papal audience is on Wednesday mornings, and Wednesday and Sunday are St Peter's busiest days.
• The Colosseum: entry is free on the first Sunday of the month, but the upper levels, the arena and the underground stay closed.
• In winter: from 25 October to 28 February, the Colosseum, Forum and Palatine close at 16:30, with last admission at 15:30. Start ancient Rome in the morning.

Day 1: Ancient Rome, then an evening walk

Morning: the Colosseum, Forum and Palatine

The Colosseum opens at 08:30, and the Forum and Palatine at 09:00. With the standard 24h ticket (€18), you get 75 minutes inside the Colosseum at your booked time, and one entry to the Forum and Palatine within 24 hours. If you'd rather not go in, the Colosseum guide covers what you can see from the street.

Afternoon: the Capitoline

Michelangelo designed Piazza del Campidoglio, on the Capitoline Hill, in the mid-16th century. The equestrian statue of Marcus Aurelius in the middle is a 1997 bronze copy; the original is inside the Capitoline Museums.

• The museums open daily from 09:30 to 19:30. A ticket is €16.50 until 1 November 2026, while an exhibition is on, and €15 when none is.
• The view: the visit includes the Tabularium gallery, whose arches look over the whole Roman Forum, to the Colosseum and the Palatine.
• Santa Maria in Aracoeli, next door, is reached by 124 marble steps, built in 1348. From the top you see across Rome to the domes of Sant'Andrea della Valle and St Peter's. Only its Mass times are published, not its opening hours.

My own afternoon there went like this:

• Santa Francesca Romana, the church on the edge of the Forum by the Colosseum, with its gilded ceiling and apse mosaic. Its visiting hours aren't published either.
• Along Via dei Fori Imperiali.
• The Forum from the Capitoline Hill, with the Arch of Septimius Severus below.
• Santa Maria in Aracoeli and Piazza del Campidoglio, around sunset.

Evening: from Piazza Venezia to Trevi

From the Capitoline, go down to Piazza Venezia. From there, my first evening's walk took in the Tiber Island, Piazza Navona, the Pantheon and the Trevi Fountain in under two hours. The Rome at night guide has the route, what was lit and what closes when. Two times matter:

• the Pantheon closes at 19:00, with last entry at 18:30;
• the Trevi Fountain's €2 ticket to the basin runs until 22:00, with last entry at 21:00. After that there's no charge.

Day 2: The Vatican

Late morning: the Vatican Museums

Go at your booked time, and allow about two hours. That's how long the Museums' own guided tour takes, and my visit, from the first photo to the last, took about an hour and three quarters.

Dress for both the Museums and St Peter's: no sleeveless or low-cut tops, shorts above the knee, miniskirts or hats. If you're going on to St Peter's, don't leave bags in the Museums' cloakroom, because St Peter's has none.

Lunch

There are cafés, a self-service restaurant and a pizzeria along the Museums' route. I had a late lunch at a restaurant just outside St Peter's colonnade, but I didn't keep its name, so I can't recommend it.

Afternoon: St Peter's

Entry is free, from 07:00 to 20:00, with last entry by 19:15, through security in the right-hand colonnade. The dome costs €17 by the stairs (551 steps) or €22 with the lift, which leaves 320 steps. I went into St Peter's late in the afternoon and came out into the square at dusk.

Late afternoon: Castel Sant'Angelo

The castle, by the Tiber, costs €18 (€2 for EU citizens aged 18 to 25). It's open Tuesday to Sunday from 09:00 to 19:30, with last entry at 18:30, and it's closed on Mondays. Tickets carry your name, and staff check your ID at the door. On the first Monday of the month, a €5 ticket, sold at the desk only, opens it from 14:00 to 20:00; in 2026 that leaves 2 November and 7 December. On my way to the Vatican, I'd passed along the Tiber by the castle.

Day 3: The Lateran and the old centre

Morning: San Giovanni in Laterano and the Scala Santa

San Giovanni in Laterano is free and open every day from 07:00 to 18:30. I went at about half past five, after dark: the obelisk outside, then the nave and apse.

At the Lateran's Scala Santa, the 28 steps are climbed only on your knees and in silence; a side staircase is there for walking up. Cover your shoulders and knees, and take no photos. The steps can be climbed from 06:00 to 13:30 and from 15:00 to 18:30 Monday to Saturday (07:00 on Sundays), closing at 18:00 from November to March. The Sancta Sanctorum chapel costs €3.50.

Afternoon: Trevi, the Pantheon and Piazza Navona

From San Giovanni, metro line A runs to Barberini, about five minutes on foot from the Trevi Fountain.

• Trevi: by day the basin area costs €2, from 09:00 (11:30 on Mondays and Fridays).
• The Pantheon: €7, with tickets in your name and no skip-the-line option, open from 09:00 to 19:00.
• Piazza Navona keeps the shape of the stadium Domitian built in AD 86.

Rome's tourist board describes the area between the Pantheon, Navona and Campo de' Fiori as a place where "you can pleasantly stroll, even without a specific destination".

Late: Trevi again

After 22:00, there's no charge at the Trevi Fountain. On my last night I went back at a quarter to two in the morning, and it was still lit.

Skip it

What to skip

• The costumed centurions at the Colosseum. Charging for photos near monuments is banned, with a €400 fine. More in the Colosseum guide.
• Websites that look like the Vatican Museums' own. Book only at tickets.museivaticani.va.
• Sitting on Trevi's basin, eating there or wading in. Fines start at €40, and at €450 for wading in.
• Paying a reseller more for entry. In October 2026, a reseller we checked charged €1 to €8 more than the official price for entry to the Colosseum, the Pantheon, the Trevi Fountain, the Capitoline Museums and Castel Sant'Angelo. The official sites are in this guide.

Questions

Is three days enough for Rome?

For the main sights, yes: a day for ancient Rome, a day for the Vatican, and a day for the Lateran and the old centre. Book the Colosseum and the Vatican Museums before you go.

Which day should I visit the Vatican?

Monday to Saturday. The Museums are closed on Sundays except the last Sunday of the month, and St Peter's is busiest on Wednesdays, for the papal audience, and Sundays.

Do I need to book the Colosseum and the Vatican in advance?

Yes. Colosseum tickets go on sale 30 days ahead and carry an entry time. In mid-October 2026, the Vatican Museums had sold out three weeks ahead.

What's free in Rome?

St Peter's and San Giovanni in Laterano, always. The Colosseum, Forum and Palatine, the Pantheon and the Capitoline Museums on the first Sunday of the month, and the Vatican Museums on the last. The Trevi Fountain can always be seen from the piazza for free.
