The tour’s main appeal lies in its ability to transport you through time—walking through tunnels and ruins that echo with the stories of ancient civilizations. It’s like being handed a key to Naples’ secret past, with plenty of fascinating details along the way.
The guided approach really makes a difference. As many reviews highlight, guides are often praised for their knowledge and enthusiasm, making the experience more engaging.

What the Tour Entails

Starting Point & Accessibility
Your adventure begins just next to the Basilica of San Paolo Maggiore, marked clearly by white and blue flags. The meeting spot is centrally located, making it easy to find. Once you arrive, you’ll skip the lines—great if you’re visiting during high season—and head into the underground system with your guide.
The Route & Highlights
The tour takes you through a series of significant archaeological sites. First, you’ll explore the remains of the Greek-Roman aqueduct, marveling at the engineering feat that supplied water to ancient Naples. Then, you’ll visit the Roman theater remains, including the relatively new Summa Cavea, a recently uncovered fragment of the old theater.
As you walk, your guide will explain how these structures fit into the city’s evolution over 2,400 years. You’ll learn about the different periods of construction, how the underground tunnels served various purposes—including water supply, defense, and storage—and how these spaces have been altered over time.
The Experience & Atmosphere
Many reviewers describe the tunnels as fascinating and sometimes eerie, especially the narrow, dark passages. Not everyone can handle the confined spaces, as some sections are only about 60 centimeters wide. Bringing a small flashlight is recommended for primary and middle school children, though adults should also be prepared for dim lighting.
The tour includes an illuminated pathway, low steps, and an access ladder with a handrail—all designed for safety but still demanding some agility. For those with mobility challenges, the tour might pose a challenge due to the 121 steps involved.
Extra Features & Add-ons
A key highlight is the multilingual app that allows you to follow the commentary in several languages, making the tour more inclusive. Photographers will appreciate that taking pictures is allowed along the way, so you can capture the ruins and tunnels for memories.
For a culinary touch, you can opt to finish your tour with a pizza meal valued up to 15 EUR. Many reviewers enjoyed this combination, describing it as a perfect way to unwind after the underground exploration.
What Makes This Tour Stand Out

Knowledgeable Guides
Reviewers consistently praise the guides for their enthusiasm and expertise, with some saying that their storytelling made the tour particularly captivating. One reviewer mentioned, “The guide was captivating,” emphasizing how a good guide can elevate the experience from interesting to memorable.
Cost & Value
At only $17 per person, the tour offers excellent value. For that price, you gain access to real archaeological gems, expert explanations, and the chance to walk through Naples’ subterranean world—something you’d probably pay much more for in a private tour.
Authentic Archaeological Sites
Seeing actual remnants of Greek aqueducts and Roman theaters adds a tangible dimension to your understanding of Naples’ past. The recent discovery of the Roman theater fragment (Summa Cavea) often excites visitors, highlighting how this underground system continues to reveal new stories.
Engaging & Fun
Many guests find the experience fun and educational in equal measure. The dark tunnels, the narrow passages, and the historical tales make for a memorable outing. One reviewer called it an “amazing experience,” praising how the guide kept the group engaged with interesting facts and humor.
Potential Downsides & Things to Keep in Mind

While this underground tour is a highlight for many, it’s not without its quirks. The narrow, low tunnels can be uncomfortable for claustrophobic visitors or those with mobility issues. The 121 stairs can be tiring and prohibit access for wheelchairs, so if you or someone in your party struggles with stairs, it’s worth considering alternative activities.
Some reviews mention large group sizes making it difficult to hear the guide clearly. While guides do their best to manage the crowds, expect some noise and chatter—especially during peak times. Arriving early or choosing a smaller group if possible might improve the experience.
The chaotic start—finding the entrance and lining up—can be a bit confusing. Travelers recommend paying attention to the signs and arriving a few minutes early. Also, the tour is non-refundable, so make sure your plans are firm before booking.
