The Caelian Hill is one of the seven hills on which ancient Rome was founded. The Roman Houses on the Celio Hill are an extraordinary archaeological site located beneath the Basilica of Santi Giovanni e Paolo on Rome's Celio Hill.

Serena was an amazing guide for our Underground Rome tour!
Serena was an amazing guide for our Underground Rome tour! She was especially wonderful with our 10-year-old—engaging, knowledgeable, and great at keeping our whole family of three interested throughout San Clemente and the Case Romane del Celio. She also gave us an excellent lunch recommendation and knew all the “secret AC” spots to help us stay cool. We highly recommend Serena for families!
Response from the operator: Dear Garret, Thank you so much for your wonderful 5-star review! We are delighted to hear that Serena made your Underground Rome experience so special, especially for your 10-year-old. We will be sure to share your kind words with her — she will be thrilled! We are also happy that her lunch recommendation and her “secret AC” spots helped make your visit more comfortable during the hot Roman summer! Thank you again for choosing Kai Travel and for recommending Serena to other families. We hope to welcome you all back to Rome with open arms on your next visit! Warmest regards, Ruth by Kai Travel

A tour worth booking
It was my first time visiting Rome and this great tour really inspired me to use my imagination and dive into a different historical time. This would not have been possible without our guide Alessandro whose professionalism and passion made every detail interesting and easy to understand. I can highly recommend to anyone who would like to have a short break from the commercial sightseeing spots and feel like an explorer of the Underworld of Ancient Rome instead!
Response from the operator: Thank you for your feedback. I will pass your kind words on Alessandro, he will definitely be enjoyed by them. I really appreciate your review, as it helps us to improve our service. Hope to see you soon back to Rome. I wish you a nice day and happy 2020! Regards

He is so expert of Ancient Rome and Underground that is aim is to share with each member of his groups, all he has learned about the past.

Unbelievable!
What an incredible experience to really see the real ancient rome away from the crowds. This was such a delight in that the places we went to we had to ourselves and the opportunity to explore as well as really soak in the experience. Alessandro was amazing and his archeological experience bought it even more to life. It was wonderful sifting through the 'fiction' to the facts as well as being able to see Rome as the empire it was. If you want to avoid the crowds and deepen your knowledge of Rome and get off the tourist track this tour is a MUST!

Stories, History, Passion -
Allessandro combines amazing detail and passion as he takes you down below street level on this awesome tour. He goes out of his way to bring history to life - he started his tour saying "I'm going to ask you many times to use your imagination" - however - he is so well prepared and knowledgable that what you find yourself doing is actually 'being there' in the past. The destinations are rich - visually and historically. What I also liked was as we walked along to the destinations he was able to speak about other things along the route - I was really impressed by the Ludus Magnus outside the Colosseum and how he explained its structure and function - this was a bonus! Allessandro is a lovely host, intellectually curious, engaging and is really interested to know what you think and feel about what you are seeing as well. Subsequent to this tour i joined a longer multi city tour throughout Italy - the 'local experts' engaged by that tour company were superficial compared to Allessandro. It is rare to spend time with someone who lives and breathes this stuffand invests time to go into the detail - and he is a cool guy as well! Highly recommended for something more substantial and the history buffs.
Response from the operator: Dear Greg, thank you so much for your review. We so enthusiastic to read how much you enjoyed the experience with my colleague Alessandro. He is very expert archeologist and owns a deep knowledge of Rome and Italy as well. Thank you for putting everything in such details and helping other guest to prepared before going. Hope to see you back to Rome in the next future, Have a lovely day

Why this scores 61
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Rome: Underground Secrets and Mysteries Private Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Rome.
How much does Rome: Underground Secrets and Mysteries Private Tour cost?
+
Prices start at $373 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 Rome: Underground Secrets and Mysteries Private 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 Rome: Underground Secrets and Mysteries Private Tour worth it?
+
It holds an Outty Ranking of 61 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 20 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 Rome: Underground Secrets and Mysteries Private 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 Rome: Underground Secrets and Mysteries Private 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 Rome: Underground Secrets and Mysteries Private Tour?
+
Around 7 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 Rome: Underground Secrets and Mysteries Private 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 Pasta and Tiramisu Class: Ravioli, Fettuccine & Fine Wine 5*, Pasta Making & Wine Tasting with Dinner in Frascati from Rome, Rome: Pizza & Tiramisu or Gelato Class with Flowing 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.
