This tour combines two sides of Rome rarely seen together — a hidden underground world most visitors never know exists, paired with one of the city's most iconic, photographed landmarks above ground. Instead of simply admiring the Trevi Fountain from the crowd like everyone else, travelers descend beneath it into Vicus Caprarius, an archaeological site discovered purely by accident, to see the actual 2,000-year-old aqueduct still feeding the fountain today — an experience accessible by guided visit only. As a fully private tour, the pace, depth of storytelling, and route are shaped entirely around your group, with no fixed schedule or crowds to compete with. It's the perfect blend of hidden, lesser-known Rome and classic, postcard-worthy Rome in a single, personalized experience.

What you'll see and do
Vicus Caprarius – the City of Water
Trevi Fountain Underground (Vicus Caprarius – The City of Water) Located roughly 9 meters beneath the Trevi Fountain district, this site reveals ancient Roman infrastructure and everyday life. The underground tour centers on the Aqua Virgo, the only ancient Roman aqueduct functioning continuously since 19 BCE, which still feeds the Trevi Fountain today. Visitors explore the Vicus Caprarius, a complex featuring a 1st-century Roman apartment block (insula) converted into a 4th-century luxury villa (domus), alongside a massive masonry reservoir (castellum aquae) where water still trickles through ancient stonework. An onsite museum showcases artifacts excavated between 1999 and 2001, including a marble bust of Cleopatra’s son (Alessandro Helios), a hoard of over 800 Roman bronze coins, amphorae, terra cotta tiles, and oil lamps. The tour takes about 30 to 45 minutes, enters via Vicolo del Puttarello 25, and requires advanced reservations due to limited underground space.

Trevi Fountain
Travelers will stand before the Trevi Fountain, Rome's largest and most famous fountain, admiring its dramatic baroque sculptures of Oceanus and his sea horse-drawn chariot carved into the back of Palazzo Poli. Your guide will explain how the fountain is still fed by the ancient Aqua Virgo aqueduct, originally built in 19 BC and still flowing nearly 2,000 years later. Travelers can take in the scale and detail of the sculptures up close, snap photos of one of the most iconic spots in Rome, and take part in the famous tradition of tossing a coin over their shoulder into the fountain, said to guarantee a return trip to the city.

Spanish Steps
Travelers will admire Rome's famous 135-step baroque staircase, built in the 1720s to connect the Piazza di Spagna with the French church of Trinità dei Monti above. Your guide will share the story behind the steps' name, their long history as a gathering place for 18th- and 19th-century artists, poets, and writers, and their enduring fame as a backdrop in films like Roman Holiday. Travelers can take in sweeping views over Piazza di Spagna from the top, see the Fontana della Barcaccia at the base, and soak in one of Rome's most photographed and romantic settings.

Why this scores 48
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Rome: Underground of Trevi Fountain & Spanish Steps Private Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Rome.
How much does Rome: Underground of Trevi Fountain & Spanish Steps Private Tour cost?
+
Prices start at €2 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 of Trevi Fountain & Spanish Steps Private Tour take?
+
Plan for about 1.5 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 of Trevi Fountain & Spanish Steps Private Tour worth it?
+
It holds an Outty Ranking of 48 out of 100, which we label "Worth a Look". That score blends traveler sentiment (0/5 across 0 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 Rome: Underground of Trevi Fountain & Spanish Steps Private Tour?
+
No. This experience is sold on a non-refundable basis, so only book a date you are confident about. Similar experiences in the city do offer free cancellation if flexibility matters more than price.
Is Rome: Underground of Trevi Fountain & Spanish Steps Private Tour suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1.5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Rome: Underground of Trevi Fountain & Spanish Steps Private Tour?
+
Around 0 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 1.5-hour experience runs outdoors or after sunset.
Where does Rome: Underground of Trevi Fountain & Spanish Steps 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 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.

Alternatively, you can take a taxi, which will drop you off directly at the entrance. Hotel pickup is not included, so plan your own transport and arrive 15 minutes early.
