Start your adventure at Vico S. Anna di Palazzo 52, nestled in the heart of the Spanish Quarters near Toledo Street and Plebiscito Square. The proximity to the Toledo metro station and Augusteo funicular station makes it an easy spot to find. The tour includes entry to Underground Naples, so you’ll bypass lines and head straight into the underground maze.
Once gathered, your guide will give a brief introduction before leading you underground. The group size is typically manageable, allowing for plenty of interaction and personalized attention.

The core of the experience is passing beneath the city streets through winding tunnels that have been used for centuries. Expect to walk through narrow, sometimes low-ceilinged passages, so comfortable shoes are a must. Reviewers note that the tunnels are dark, so rely on your guide’s lighting and be mindful of uneven surfaces.
Guides like Massimo and Agostino keep the atmosphere lively, sharing stories about Naples’ transformations over thousands of years. You’ll learn how the city evolved from Greek times into the modern era, with the tunnels playing roles as water channels, secret passages, and wartime shelters. As one reviewer put it, “Augustos was great! This story of Naples underground is unbelievable.”

One of the highlights is the ancient Neapolitan aqueduct, which was originally built by the Greeks. You’ll get to see this impressive structure and hear about how it supplied water to the city for centuries. Some parts of the aqueduct served as hiding spots during WWII, turning into air-raid shelters that saved lives during bombings.
One reviewer mentioned that the tour was “really interesting and exciting,” especially when learning how these tunnels were used as underground shelters during WWII. The walls also feature old writings and markings, giving a glimpse into the lives of past inhabitants.

Throughout the tour, guides do an excellent job blending historical facts with stories, making the experience both educational and entertaining. Reviewers repeatedly praise guides like Alex and Agostino for their humor and storytelling skills, turning what could be a plain walk into an engaging adventure. Comments like “great stories and learned a lot” and “very funny and informative” show how much personality guides bring to the experience.

The tour is not suitable for people with mobility impairments, claustrophobia, or wheelchair users. The tunnels are narrow, dark, and uneven, which could pose challenges. Still, many reviewers note that the guides are attentive, offering options to avoid the tightest spaces if needed.

At just $14 per person, this tour offers excellent value. For an hour of immersive underground exploration, you get a comprehensive look at Naples’ hidden history — something that many city tours simply can’t match for the price. The brief duration means it’s easy to slot into a busy sightseeing schedule, and you can combine it with other activities later in the day.

Most reviews agree that guides like Alex, Agostino, and Eduardo bring extra life to the tour. Their storytelling, combined with the fascinating sights, makes this a memorable part of any Naples visit. The tour’s focus on historic transformation and survival stories adds layers of meaning, making it more than just a walk through tunnels.

We appreciated how the guides weave stories into the walk—highlighting how the aqueducts and tunnels played roles beyond simple infrastructure, such as how they saved lives during wartime. The authentic atmosphere of the underground passages, complete with old graffiti and stonework, makes it feel like stepping back in time.
The main consideration is that some parts of the tour are dark, tight, and uneven. For travelers with mobility issues or claustrophobia, this could be uncomfortable. Also, since the tunnels are quite old, the experience can be physically demanding in some sections.
