Visiting Naples Underground: Hours, Tickets & Entrances
"Naples Underground" is not a single door in the pavement. Several separate sites sit beneath the historic centre, each with its own entrance, ticket and character. Knowing which is which before you book is the difference between the tour you wanted and a surprise.
The main entrances
Napoli Sotterranea — Piazza San Gaetano
The best-known route drops about 40 metres below the streets near Piazza San Gaetano. It follows the Greek-Roman aqueduct and its cisterns, passes through tunnels that sheltered families during the Second World War, and ends at a buried Roman theatre reached through a building above street level. Tours run in Italian roughly every hour and in English at limited times, typically around midday and mid-afternoon — always confirm the English slot at the desk.
The Spanish Quarters underground — Vico S. Anna di Palazzo 52
A guided walk beneath the Quartieri Spagnoli enters the same tuff-and-aqueduct world from a different door at Vico S. Anna di Palazzo 52. This is the address, opening hours and map used on this site, and it is the most-reviewed underground tour in the city.
Neapolis Sotterrata — San Lorenzo Maggiore
Under the San Lorenzo Maggiore complex lie the excavated Roman streets and market of ancient Neapolis. Several city walking tours include this site rather than the aqueduct — a genuinely different experience, and worth checking which one your tour visits.
The Bourbon Tunnel — Galleria Borbonica
A nineteenth-century tunnel built for the royal family, later a wartime shelter and vehicle pound. It has its own entrance on Via Domenico Morelli and is not part of the ancient aqueduct at all.
Hours
The Vico S. Anna di Palazzo entrance opens 09:30–16:30 Monday to Friday and 09:30–18:00 on Saturday and Sunday. Other entrances keep their own timetables, and English departures are always more limited than Italian ones, so plan around the language you need.
Tickets and prices
Entry tickets start around $21–$22. Guided tours that pair the underground with a walk through the historic centre cost more depending on what they include. Booking ahead matters most in high season and for the limited English-language slots. Compare every option, side by side, on the tours page.

Before you go
- Wear closed, comfortable shoes — floors are uneven and can be damp.
- Bring a phone with a torch; the narrowest passages are dark.
- The underground stays cool all year, a welcome escape from summer heat above ground.
- Confirm the meeting point when you book — operators gather at different squares (San Gaetano, Bellini, Dante, Gesù Nuovo or Municipio).
