What you get

    About this experience

    This is a small and intimate group walking tour of no more than 12 people. We'll start by the Spanish steps, where you'll learn everything about them and why they're called like this (you'll be surprised!). By the Spanish steps we'll meet the first fountain of the tour. This is where we'll begin a journey through the aqueducts of Rome! In fact this fountain is still fed today by an ancient Roman aqueduct built in 19BC! From here we'll follow the aqueduct which is, for the most part, underground. And by casually walking through this itinerary we’ll find parts of the aqueduct appearing between the modern buildings. We'll follow the aqueduct until its monumental end: the Trevi fountain. But we won't stop here. We'll get away from the crowds, turn the corner and discover the underground water reservoir that the ancient Romans built over 2000 years ago! During this walking tour you won't just see the specific site, but learn also how modern Rome was built around the ancient ruins.

Then we'll learn about the iconic fountain of la Barcaccia, which is still today fed with an ancient Roman aqueduct of over 2000 years! And this is where our journey through water starts..

    Amazing tour guide

    What an amazing experience. Our tour guide was so passionate, knowledgeable and also funny which really made the experience amazing. We learnt so much and noticed things we never would have if it wasn't for the tour. I will definitely re-book with the same company next time we come to Rome.

    Response from the operator: Thank you so much for taking the time to write such wonderful words! 😊🧡 We're super happy you enjoyed the tour with us and we hope to see you again soon next time you're in Rome 😊🙌

    Amazing tour guide

    What an amazing experience. From start to finish our tour guide was so passionate, knowledgeable and also really funny. She made the experience so much better than I anticipated. We learnt so much about the area and noticed things we never would have if it wasn't for the tour. When we return to Rome we will definitely be booking with the same company to try out a different tour.

    Tracing aquaducts

    Although it was hot, we enjoyed this walking tour. The highlight was the end of the tour when you saw the remnants of the aquaduct. Very informative tour.

    Response from the operator: Thank you so much, we're so happy you enjoyed the tour with us :)

    Trevi Fountain Underground Aqueduct and Spanish Steps Tour: questions travelers ask

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

    How much does Trevi Fountain Underground Aqueduct and Spanish Steps Tour cost?

    +

    Prices start at $47 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 Trevi Fountain Underground Aqueduct and Spanish Steps Tour take?

    +

    Plan for about 2 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 Trevi Fountain Underground Aqueduct and Spanish Steps Tour worth it?

    +

    It holds an Outty Ranking of 82 out of 100, which we label "Exceptional". That score blends traveler sentiment (4.9/5 across 197 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Rome, and how flexible the cancellation terms are.

    Can I cancel or reschedule Trevi Fountain Underground Aqueduct and Spanish Steps 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 Trevi Fountain Underground Aqueduct and Spanish Steps Tour suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 2-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Trevi Fountain Underground Aqueduct and Spanish Steps Tour?

    +

    Around 69 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-hour experience runs outdoors or after sunset.

    Where does Trevi Fountain Underground Aqueduct and Spanish Steps 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.
