What this ticket actually opens
This is the official route into Napoli Sotterranea, the tunnel system under Piazza San Gaetano, and the fare covers both halves of it: entry, and the guide who takes you round. You cannot buy one without the other here, because the walk is not one you are allowed to make alone. Ninety minutes to two hours below ground, roughly forty metres down, on the route the operator runs itself rather than a version of it assembled by a third party.
What you skip by booking ahead is the ticket queue at the entrance, which in July and August is the difference between arriving and starting. It is a shorter wait rather than a priority lane, and the wording is careful about that.
Five things this ticket gives you
The full aqueduct stretch
Plastered channels cut for water and later widened by just enough for a person. This is the section you walk along rather than look at.
Cisterns that still hold water
Sealed chambers filled from the channels above, green and completely still, with the old waterline legible on the wall.
The Roman theatre and Summa Cavea
The theatre of Neapolis survives inside later buildings, and its upper seating tier has recently been brought back into the route.
The wartime shelter
Bunk frames, tins, toys and charcoal drawings left by families who sat out the air raids between 1940 and 1944.
The candle, if you want it
A short passage barely shoulder-wide, walked by candlelight to a Roman cistern. Optional, and the group waits for you either way.
Ninety minutes to two hours, and where they go
The descent is 136 steps and takes a few minutes. The quarry chambers come first, then the longest single stretch of the visit in the aqueduct channels, then the cisterns. The candlelit passage sits about two thirds of the way through. The shelter and the theatre close the route, and you climb the same stair back to via dei Tribunali.
A free multilingual app covers languages beyond English and Italian, and a printed multilingual brochure is handed out at the start, so a group with mixed languages works better here than it does on most guided walks.
Why this ticket is non-refundable, and what to do about it
This listing is sold non-refundable. That is unusual among the Naples underground tickets and it is stated plainly rather than buried, so treat the date you pick as the date you are going. In exchange you get the operator's own departure at a fixed hour, on a timetable that runs from 10.00 to 18.00 every day and adds a 21.00 slot on Thursdays.
If your dates are still moving, book the Spanish Quarters route instead. It is the same city below, at the same fare, and it refunds in full up to 24 hours before you go.
Fixed date, fixed hour, official route
Ninety minutes to two hours in the tunnels under Piazza San Gaetano, with the ticket queue skipped and a guide the whole way.
Who this suits, and who should book something else
Book this if
You want the route everybody means when they say Naples Underground, you know which day you are free, and you would rather spend the whole booking below ground than walk the streets first. At this fare it is also the cheapest way into this particular system.
Book something else if
Your plans might change — take the Spanish Quarters tour, which refunds. Stairs are a problem — the Neapolis Sotterrata is ten metres down and step-free. Or you want the old town as well as the tunnels, in which case a walking tour wraps this hour inside a longer circuit.

Finding the entrance on Piazza San Gaetano
The meeting point varies with the option you book, and the square is the single most confusing address in this whole subject. Number 69 is Napoli Sotterranea; number 316, on the same piazza, is San Lorenzo Maggiore and a completely different underground. A traveller who has done it puts the direction better than a map: face the basilica and take the small road on the left, not the entrance across the square.
Doors, metro stops and walking times are on getting to the entrances. Dante and Museo on Line 1 are both five to ten minutes away.
Know before you go
- 136 steps down and back up, low and handrailed, with no lift.
- Flat shoes and a sweatshirt, even in August. The temperature drops about a third of the way down.
- A small torch for school-age children. Candles are not handed to children.
- Pushchairs stay at the entrance and are collected on the way out.
- Photography is fine. The light is warm and low; bracing against a wall beats raising the exposure.
- Not suitable for wheelchair users, for anyone with limited mobility, or in pregnancy — and claustrophobia is named too, though the one tight stretch is the optional one.
What travellers say about this tour
Good English from the guide and plenty of detail. A group of thirty-five still heard everything. One warning: the Naples Underground meeting point is not obvious — face the basilica and take the small road on the left, not the entrance across the square.
Caroline · United Kingdom · August 2026
Getting underground and out of the heat was a relief in itself. The tunnels and the theatre sit under streets you would otherwise walk straight past.
Stephen · Australia · August 2026
Interesting throughout, though part of the route runs through genuinely narrow tunnels and there is a little waiting.
Sabrina · Austria · August 2026
Two hours with Massimiliano, covering both the tunnels and a Roman theatre tucked inside a house.
Marco · Spain · August 2026
Excellent on the aqueducts and the amphitheatre. The guide’s English was good but softly spoken, and hard to catch at times.
Helen · United Kingdom · August 2026
Naples Underground was interesting and well organised throughout. The pizza included in the offer was very good too, though it adds up for a family of four.

Questions about this ticket
Is this the official Napoli Sotterranea route?
Yes. It is sold by the operator that runs the site, and the fare covers both the entry ticket and the guide who takes you round.
Can I walk it without a guide?
No. The walk is not made autonomously here — a guide accompanies every group. If walking alone matters to you, the Neapolis Sotterrata under San Lorenzo Maggiore allows it, with a free audio guide.
What happens if I skip the narrow passage?
You wait at the wider end for roughly ten minutes while the group goes through, and then everybody continues together. Nothing else on the route is tight.
Is the pizza worth adding?
It buys a Margherita or Marinara up to fifteen euros with a soft drink, after the tour. One reviewer with a family of four found it added up; a couple will find it straightforward.
Really no refund at all?
Correct — this listing is sold non-refundable. The Spanish Quarters tour costs the same and refunds in full up to 24 hours before.
How busy does it get?
It carries more reviews than everything else in this subject put together, so expect company. One reviewer describes a group of thirty-five that still heard everything, because the guide works the acoustics.
