Naples Underground tour review
What the tour is like
This isn’t a burial site — it’s the engineering underworld of Naples: Greek-cut tufa quarries, Roman aqueduct channels, vast cisterns and the tunnels that sheltered Neapolitans during WWII bombing. Expect narrow passages and some steps; it’s more adventurous and atmospheric than the wide catacomb galleries.
What works
- A completely different layer of underground Naples
- Atmospheric narrow passages and huge cisterns
- The wartime-shelter story is moving
- Central, easy to combine with the old town
Worth knowing
- Narrow squeezes and steps — not for the claustrophobic
- Not wheelchair accessible (unlike San Gennaro)
- Busier and more mainstream than the catacombs
Do this in the centro storico and the catacombs up in the Sanità on the same trip — together they show the two very different undergrounds of Naples.
Who it’s for
Visitors who want the engineering-and-history underground rather than a burial site, and those comfortable with narrow spaces. Prefer something step-free and spacious? Choose the Catacombs of San Gennaro.

Frequently asked questions
Is Naples Underground the same as the catacombs?
No — Naples Underground is the Greco-Roman aqueduct and cistern system (plus WWII shelters) beneath the centro storico, not a burial site. The catacombs are early-Christian cemeteries up in the Sanità.
Is it claustrophobic?
It can be — there are narrow passages and steps. If you prefer wide, step-free galleries, the Catacombs of San Gennaro are the better choice.
Why does it have so many reviews?
It’s one of the most-booked things to do in central Naples, which is why it has tens of thousands of ratings — a 4.4 average across that many reviews is a strong, consistent score.
