Discover Naples' underground secrets on this 3.5-hour walking tour. Explore ancient tunnels, Roman ruins, and WWII shelters with expert guides.
Traveling to Naples? You’re probably enchanted by its vibrant streets, historic architecture, and mouthwatering cuisine. But what if I told you there’s a hidden world beneath your feet that reveals even more about this extraordinary city? That’s exactly what the Naples City Center Walking Tour with Underground Naples offers—a fascinating journey into the subterranean layers of Naples, some dating back 2,400 years.
What we love most about this experience is how it combines history, adventure, and authentic local insights into one compact tour. Plus, the diverse highlights—ranging from ancient aqueduct ruins to WWII air raid shelters—promise a well-rounded look at Naples’ layered past. That said, a potential consideration is the tour’s underground sections, which involve narrow tunnels and some claustrophobic spaces, so it might not be suitable for everyone. This tour is perfect for history buffs, curious travelers, and those eager to see a side of Naples few get to experience.


Your journey begins at Piazza del Gesu Nuovo, a lively square packed with history and local energy. Meeting under the statue at the center, you get a brief orientation before heading into the streets with your guide. The walk through Spaccanapoli then sets the scene—these bustling streets are the heart of Naples, filled with life, shops, and stories.
Travelers have enthusiastically described guides like Sharon and Giovanni as knowledgeable and friendly, often going above and beyond to ensure everyone feels welcomed. This personal touch makes an otherwise busy city feel more intimate and engaging.

The balance between storytelling and sightseeing keeps the energy high, making the walking part enjoyable rather than exhausting.
The highlight of this tour is Underground Naples, where you’re guided into a world that feels both ancient and surprisingly well-preserved. Expect to descend 40 meters into tunnels, caves, and ruins that span centuries.
The visit includes a Greek-Roman aqueduct, dating back to ancient times, with remnants of the aqueduct walls and water channels that once supplied the city. You’ll also see a cavern used as a water cistern from the 4th century, which demonstrates how residents stored and managed water centuries ago. Some reviewers have described these spaces as “fascinating” and “amazing,” especially when contemplating the engineering skills involved in their construction.
Beyond the aqueducts, the underground tour also reveals WWII air raid shelters, which bring a stark contrast to the ancient ruins. These tunnels, once used to protect civilians during bombings, provide a sobering perspective on the city’s resilience. The narrow, sometimes low-ceilinged sections can feel a bit claustrophobic—something to keep in mind if you’re sensitive to tight spaces.

Another interesting feature is the ruins of an ancient Roman theater, offering a glimpse into entertainment in ancient Naples. Walking through these remains, you get a sense of how the city has been continuously inhabited and adapted over thousands of years.

The entire underground section lasts about 1 hour and 30 minutes, blending seamlessly with the above-ground walking. The total tour takes roughly 3 hours and 30 minutes, providing a comprehensive yet manageable experience. Group sizes are limited to 15 travelers, fostering interaction and personalized attention from guides like Giovanni or Monica.
The cost is $80.67 per person, which covers both the expert guide and the entrance to the underground site. This is considered a fair value, given the range of sites visited and the depth of information provided. The tour also works well with travelers who have moderate physical fitness—you’ll be walking on uneven surfaces through tunnels, but no strenuous climbing is required.
If you’re someone who enjoys history, archaeology, or urban exploration, this tour will hit the spot. It’s perfect for travelers who want more than just surface-level sightseeing, offering authentic insights into Naples’ layered past. It’s also well-suited for those with a moderate physical level, comfortable with walking and bending through narrow tunnels.
However, it’s worth noting that claustrophobic travelers might find parts of the underground experience challenging. Also, since the tour is not inclusive of private transportation, those unfamiliar with public transit should plan ahead to reach the meeting point at Piazza del Gesu Nuovo.
