How to Visit Naples Underground: Tickets, Hours, Tours and Everything You Need to Know (2026)
Short answer: pick which of the four undergrounds you want before you pick a tour, because they are four different sites with four different tickets. The famous one is Napoli Sotterranea at Piazza San Gaetano 69, it is 136 steps down with no lift, and you cannot walk it without a guide. Book ahead to shorten the queue, wear flat shoes and take a sweatshirt even in August.
The three things visitors get wrong
Almost every problem people report starts in one of three places, and all three are avoidable before you leave your hotel.
- They book the wrong underground. Four separate sites answer to the name, and two of them share a square. Piazza San Gaetano 69 is Napoli Sotterranea; number 316 is San Lorenzo Maggiore and a different excavation entirely.
- They underestimate the steps. 136 of them, down and back up, with a handrail and no lift.
- They assume they can wander. On the official route you cannot: a guide is with the group throughout, and that is not an upsell, it is the only way the site is visited.
Sort those three out and the rest is straightforward. Every listing on underground guided tour says which underground it enters and how long it spends there.
Which underground do you actually want?
This is the decision that matters, and it is not the same as choosing between operators. The four sites differ in depth, in what is down there, in whether you may walk alone and in whether a wheelchair can get in.
| Site | Where | Depth | The pitch |
|---|---|---|---|
| Napoli Sotterranea | Piazza San Gaetano 69 | About 40 m | The full quarry, aqueduct, shelter and Roman theatre route |
| LAES, Spanish Quarters | Vico S. Anna di Palazzo 52 | Not published | One tight hour, entered from a residential lane |
| Neapolis Sotterrata | Piazza San Gaetano 316 | About 10 m | A Roman market street, walkable alone, step-free |
| Catacombs | Via Capodimonte 13 / Via Sanità 123 | Hillside galleries | Early Christian burial galleries and frescoes |
Depths and access as published by each operator.
The four undergrounds sets them out in full, with what each ticket opens.
Tickets, prices and what a fare covers
Three of the four publish a door price. Napoli Sotterranea does not — its figure appears only inside its own booking flow — which turns out not to matter, because every listing that enters it already includes the entry ticket. San Lorenzo Maggiore charges €9 at the desk with a €2 guided-visit supplement; the catacombs charge €13 for a ticket that opens the second catacomb free for a year.
Guided tours and entry tickets here run from $10 to $89. The bottom of that band is a ticket where all the time is spent below ground; the top is a three-and-a-half-hour walk where ninety minutes of it are.
Check the time below ground, not the tour length. Across comparable Naples walking tours the underground share runs from twenty minutes to an hour and a half for similar money. It is the one number that decides value here — the decision guide tabulates all of them.
When to book, and when you can just turn up
The catacombs require a reservation and will not slide you into a later slot if you miss yours. Napoli Sotterranea takes bookings but not for groups under fifteen, other than for tours in languages beyond Italian and English, dedicated small-group guides and the Thursday 21.00 slot. San Lorenzo Maggiore is the walk-up option — except between 15 June and 30 September 2026, when it runs guided visits only on a fixed timetable.
Booking ahead on the official route buys a shorter entrance queue rather than a priority lane. In August that is still worth having. Hours and departure times has every timetable in one table.
Getting to the right door
Dante and Museo on metro Line 1 both leave you five to ten minutes from Piazza San Gaetano. Toledo is closest to the Spanish Quarters. For the catacombs, Museo and then the bus or a twenty-five-minute walk up into the Sanità.
Meeting points are not entrances. Half the departures here gather in a public square — Piazza Bellini, Piazza del Gesù Nuovo, Piazza Municipio, Piazza Trieste e Trento — and walk to the door together. The address on your booking may be nowhere near the tunnels. Getting to the entrances lists both.
How long to allow
| If you have | Book | Time below ground |
|---|---|---|
| One hour | The Spanish Quarters route, or a catacomb | The whole hour |
| Two hours | The official Napoli Sotterranea ticket | 90 minutes to two hours |
| Half a morning | A small-group walk with a descent built in | One hour of two and a half |
| A full day | Two undergrounds and lunch between them | Two to three hours total |
Typical time commitments, from the listings.
Two sites in a day is comfortable; three is a scramble, and the reason is timetables rather than distance. The one-day itinerary sequences it.
What to wear and what to leave behind
- Flat shoes. Worn steps, damp in places, and Neapolitan basalt paving on the way there.
- A sweatshirt, even in August. You feel the temperature drop about a third of the way down.
- A small torch if you have school-age children. Suggested at the door; candles are not handed to children.
- Leave the pushchair at the entrance. It is collected on the way out.
- Bring the camera anyway. Photography is permitted, and the warm low light is worth the effort of bracing against a wall.
Who should pick a different route, and which one
The official route names wheelchair users, people with limited mobility, pregnancy and claustrophobia. The Spanish Quarters route names the first three too. If any of that applies, you have two good options rather than none: the Neapolis Sotterrata is ten metres down and described as wheelchair accessible, and the superstition walk covers the underground legends without leaving street level. Steps and access compares every route.
The one genuinely tight stretch on the official route is optional. If you would rather not take it you wait roughly ten minutes at the wider end and rejoin the group — nobody is left behind, and the rest of the path is lit and wide. Full detail on the path.
Combining it with the rest of the centre
Everything above the tunnels is walkable, which is why the walking tours are worth the extra money for a first visit. Via dei Tribunali runs directly over the aqueduct. San Gregorio Armeno and its year-round nativity workshops are one street away. Spaccanapoli cuts the old town in half a few minutes south. Coming up from an hour underground and standing on the street you have just walked beneath is the best thing about doing both in one booking.
