    Terrific guide, hidden gem

    Our guide, Fabio, was a virtual encyclopedia of knowledge about the history of the Basilica of San Clemente and the other venues we visited. We thoroughly enjoyed learning about the centuries of churches excavated under the main basilica and how they were discovered. A gem in Rome that wasn’t terribly crowded which made it much easier to enjoy.

    Fascinating churches, excellent guide

    Fascinating visit to San Clemente to see not only the “modern” basilica but two other churches buried beneath it that have been excavated over the last two hundred years. Our guide Fabio provided excellent and detailed information on each level of the basilica.Then we visited the Monache Agostiniane Santi Quattro Coronati and San Giovanni in Laterano. Fabio’s extensive knowledge and fluent English made this one of the most interesting tours we’ve ever taken while in Rome. Highly recommend it.

    Amazing

    Wow. What an amazing experience. It is obvious that Rebecca has a passion for history and her knowledge is impressive. We toured with our 2 small children and Rebecca treated them as friends. She was sure to include them and make the whole tour lots of fun. Cannot recommend enough.

    Superb from start to finish!

    This Tour really was an excellent experience offering something quite different & very special. Rebecca’s knowledge & passion for her subject was so clear.. she kept us completely enthralled with so much information.. but it was never tedious.. & the mosaics & frescoes we viewed were truly wonderful! The organisation was superb & everything went like clockwork. Definitely this tour must not be missed!

    Hidden gem

    Wow, what a fantastic tour and hidden gem that is just off the beaten path of the Rome tourist trail. Becca is an absolutely fantastic, passionate tour guide - we learnt so much that we never would have been able to discover on our own. All the adminstration was seamlessly taken care of, the company were professional and there was no stress at all on the day. I would highly recommend this tour to others and look forward to doing another tour, hopefully with Becca as our guide again soon in the future.

    Underground Rome: San Clemente Basilica Tour: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Rome.

    How much does Underground Rome: San Clemente Basilica Tour cost?

    +

    Prices start at $76 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Rome usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Underground Rome: San Clemente Basilica Tour take?

    +

    Plan for about 3 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Rome is not rushed.

    Is Underground Rome: San Clemente Basilica Tour worth it?

    +

    It holds an Outty Ranking of 62 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 6 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Rome, and how flexible the cancellation terms are.

    Can I cancel or reschedule Underground Rome: San Clemente Basilica Tour?

    +

    Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

    Is Underground Rome: San Clemente Basilica Tour suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 3-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Underground Rome: San Clemente Basilica Tour?

    +

    Around 2 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Rome can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Rome and add a light layer if any part of the 3-hour experience runs outdoors or after sunset.

    Where does Underground Rome: San Clemente Basilica Tour start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Rome within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Rome?

    +

    Rome runs on skip-the-line access. The Colosseum underground, the Vatican before opening, and the catacombs south of the walls all require a licensed operator, and the price gap between the good ones and the rest is smaller than you would expect. We rank by guide credentials, group size and how reliably the promised access actually materialises. On Outty we rank every Rome experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Rome Pizza & Gelato Class with Wine by Cooking Italy, Rome [4in1] Pasta Making_Tiramisù_Wine Tasting_Secret Cellar, Rome Pasta and Tiramisu Class: Ravioli, Fettuccine & Fine Wine 5*. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Rome?

    +

    April, May, September and October. August is hot and half the city is shut. Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Rome?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.

    What is included in Underground Rome: San Clemente Basilica Tour?

    +

    Included: Small Group Guided Tour; For peace of mind you will receive guide's name and phone number the night before the tour; and Admission fees. Not included: Private transportation; and Food/Drinks not included. Always check the voucher for the final list before you travel.

    What languages is Underground Rome: San Clemente Basilica Tour offered in?

    +

    It runs in English. Pick your language when choosing a date and time, as not every departure runs in every language.

    Will I get instant confirmation and a mobile ticket for Underground Rome: San Clemente Basilica Tour?

    +

    Confirmation is sent by the operator after booking, usually within 48 hours; if it is not confirmed you are not charged. Mobile tickets are accepted, so you can show the voucher on your phone.

    Is Underground Rome: San Clemente Basilica Tour wheelchair or stroller accessible?
