Daniel was our guide and...
Daniel was our guide and he did such a great job! We ended up being the only 2 on the tour so we received personalized service - even found one of the public water fountains for us to fill our water bottles! Lots of walking and extremely hot, but exactly what we wanted to see. Thank you!
Response from the operator: Thank you so much, we are glad to hear that you enjoyed our guided tour with Daniel!

Unique tour
Going deep to history of church and relics . Nice tour with 4 people group and Daniel our tour guide was very educated. We loved it …
Response from the operator: Thank you so much, we are glad to hear that you enjoyed our Underground temples and Relics tour with Daniel.

Very knowledgeable and friendly. Great way to see some of the best churches in Rome. Great for solo, family and friends as well.
Response from the operator: Thank you so much! We are glad to hear that you enjoyed our Underground Temples and Relics guided tour!

Not as described
Unfortunately the reason we did the tour was because of the Christian relics including the wood from the cross, nail from crucifiction, thorns from the crown, and the wooden sign saying “King of the Jews” that was above the cross. None of those things were shown on the tour. When we asked about them half way through the tour, we were told it was at the first location we visited but not available for viewing. Then in another church we visited, we were told there was the seat of Jesus at the last supper in the room that cost $3 to see but wasn’t part of our tour. Why was that not part of our tour. We wouldn’t have cared about paying $3. Add our guide was very cynical in his delivery of information. He spoke perfectly English as he was from America, but I had a much harder time following his delivery than any of the other tour guides with a strong accent. I felt like I was back in college in history class where the professor had a wealth of knowledge but spoke down to the class. I walked away feeling like I learned nothing and probably missed a lot of valuable knowledge because of the cynical delivery.
Response from the operator: Thank you for taking the time to share your feedback. We're sorry to hear that the tour didn't meet your expectations. We understand that seeing the Christian relics, the nail from crucifixion and the wooden sign was one of the main reasons you booked this experience and that it must have been disappointing to not have seen them, so we're sorry this wasn't made clear during the tour. We're also sorry to hear that our guide's presentation style wasn't to your liking. We know that every guest has different expectations, and while many visitors appreciate his depth of knowledge, we understand that his approach didn't resonate with you. Your comments will be taken into consideration as we are always looking for ways to improve the experience we provide. Thank you again for your feedback, and we hope you'll consider joining us again in the future.

Why this scores 75
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Rome: Underground Temples and Crucifixion Relics Walking Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Rome.
How much does Rome: Underground Temples and Crucifixion Relics Walking Tour cost?
+
Prices start at $55 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 Temples and Crucifixion Relics Walking Tour take?
+
Plan for about 2.5 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 Temples and Crucifixion Relics Walking Tour worth it?
+
It holds an Outty Ranking of 75 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.8/5 across 91 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 Temples and Crucifixion Relics Walking 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 Temples and Crucifixion Relics Walking Tour suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 2.5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Rome: Underground Temples and Crucifixion Relics Walking Tour?
+
Around 32 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 2.5-hour experience runs outdoors or after sunset.
Where does Rome: Underground Temples and Crucifixion Relics Walking 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.
