Rome: Spanish Steps to Trevi Fountain Underground Tour

Planning a trip to Rome usually involves iconic sights like the Trevi Fountain and the Spanish Steps. But what if you could see these famous landmarks from a completely different perspective — underground, where ancient engineering still flows beneath the city? That’s exactly what this small-group tour offers, guiding you through the hidden waterworks that helped shape Rome’s history.

We’re impressed by how this tour combines storytelling, authentic ruins, and the chance to step into some of the city’s lesser-known underground sites. Two aspects stand out: the personalized attention that comes from small groups (no more than 12 participants) and the exclusive access to ancient aqueducts still carrying water today.

However, one thing to consider is that the tour involves walking through narrow underground passages and some uneven surfaces. Travelers who dislike tight spaces or have mobility issues might want to think twice.

This experience is ideal for history buffs, architecture lovers, or anyone curious about how Rome’s water system enabled its growth. It’s perfect for those wanting an engaging, educational adventure that’s off the beaten path of typical sightseeing.

Exploring the Itinerary: What You’ll Experience

Starting Point: Piazza di Spagna

Your adventure begins at the iconic Piazza di Spagna, right next to the famous Spanish Steps. Here, your guide will introduce you to the location’s history and answer questions about why they’re called the Spanish Steps (hint: it’s more complicated than it sounds). The starting point sets the tone for a leisurely stroll through Rome’s elegant streets before diving underground.

The First Fountain: A Water Source with Deep History

Next, you’ll visit the first of the tour’s fountains, a small but significant water feature fed by an ancient Roman aqueduct built in 19 BC. This fountain’s ongoing water supply is a testament to Roman engineering that has lasted over two millennia. As one reviewer noted, “This fountain is still fed today by an aqueduct built in 19 BC,” which underscores how well-preserved and functional these ancient works are.

Following the Aqueducts Underground

From this point, your guide will lead you along the underground pathways of the aqueducts, many of which are hidden beneath modern buildings. Expect to see parts of the aqueducts appearing between shops and streets, giving you a rare glimpse of how Romans routed water beneath their bustling city.

Several segments of the aqueduct are accessible during the tour, allowing you to see the water still flowing through the stone channels. As one reviewer remarked, “We got to see the aqueduct under the shopping mall, and the underground storage tanks, which were amazing.” This kind of behind-the-scenes look is what makes this tour special.

The Trevi Fountain — More Than Just a Photo Op

The tour culminates at the famous Trevi Fountain, where you’ll get to appreciate its grandeur and learn about its water source. But the journey doesn’t end here. Instead, your guide will turn away from the crowds and lead you underground to a water reservoir built over 2000 years ago — a true hidden gem.

This underground site offers a fascinating perspective on Roman water storage, and many reviews emphasize how captivating this part of the experience is. One traveler shared, “Getting away from the crowds and seeing the underground water reservoir made the tour worth it alone.”

Why This Tour Offers Great Value

Priced competitively for a 2-hour guided experience with small-group intimacy, this tour provides a comprehensive look at Rome’s water infrastructure. Entry to the Vicus Caprarius site and underground aqueduct sections are included, saving you the hassle and expense of separate tickets. The guide’s knowledge ensures you understand not just what you’re seeing, but why it matters.

Compared to typical walking tours that might focus solely on surface sights, this experience offers depth and context, making it especially valuable for travelers eager to learn how ancient Rome’s engineering shaped its urban development. As one review sums up, “The stories and explanations brought history to life. This is about more than just seeing ruins; it’s understanding Rome’s lifeblood — its water.”

Group Size and Comfort

The small size of the group means plenty of opportunity to ask questions, take photos, and get personalized insights. The guides are highly praised for their passion and clarity — “Marcelo’s explanations made complex engineering easy to understand,” wrote one traveler.

Accessibility and Practicalities

The tour runs rain or shine, and meeting is straightforward — next to the Diesel store at Piazza di Spagna, where guides wave a sign with the tour logo. The duration is just two hours, making it a manageable add-on to a day of sightseeing. Keep in mind, some underground passages may be narrow or uneven, so comfortable shoes are recommended.
