What are you actually paying for?
Two different things are sold under one phrase. A door price is admission to a site, charged in euros by the organisation that runs it. A tour fare is a place on a departure, quoted in dollars on a booking platform, and it already contains the admission.
Confusing the two is how people end up thinking a nine-euro site is a twenty-one-dollar one. They are both true, of different things.
The published door prices
Three of the four undergrounds publish a price you can pay at the desk. One does not.
| Site | Full | Reduced | Child | Free |
|---|---|---|---|---|
| Neapolis Sotterrata, San Lorenzo Maggiore | €9.00 | €7.00 Artecard, teachers, university students, over-65 | €6.00 under-18 | Under 6 |
| Catacombs, one or both | €13.00 | €9.00 students and over-65 | €6.00 | Under 6, and disabled visitors |
| Miglio Sacro walking tour | €19.00 | €16.00 students and over-65 | €11.00 under-18 | — |
| Napoli Sotterranea | Not published | — | — | — |
Door prices in euros, from each operator’s own website, checked 26 August 2026.
Why is one price missing from that table?
Napoli Sotterranea does not publish an on-the-door admission figure on any page of its website. The number appears only inside its own booking flow. Rather than copy a figure from a third-party blog and let it quietly go stale, no door price for that site is quoted anywhere on these pages.
In practice it does not cost you anything, because every listing that enters it includes the entry ticket in the fare. What you book is what you pay, and the lowest of those fares is $21.
This is a deliberate editorial decision rather than an oversight. A price quoted from an unverifiable source is worse than no price, because nobody re-reads it when it changes. The disclosure says where every figure here comes from.
What does a tour fare add on top?
A guided fare buys three things a door ticket does not: a departure time you have already secured, a guide, and on several products a shorter wait at the entrance. On the two tunnel routes it also buys the only access there is, because neither sells an unguided ticket.
| Kind of booking | Price band | What the extra buys |
|---|---|---|
| Entry ticket, direct | $10 – $21 | Admission, and on three of the four a guide |
| Small-group city walk with a descent | $33 – $37 | An hour below plus 90 minutes of guided old town, cap 15–16 |
| Larger walking tour with a descent | $71 – $89 | Longer routes, up to 40 people, 20 minutes to 90 below ground |

Reductions, and who actually qualifies
The two sites that publish prices are generous about this. San Lorenzo Maggiore gives €7 to Artecard holders, teachers, university students and over-65s, and €6 to under-18s. The catacombs give €9 to students and over-65s, €9 with ArteCard, €10.40 to Touring Club and FAI members, and free entry to under-6s and disabled visitors.
Booking platforms handle child pricing differently: several listings offer a discounted child rate at the booking step rather than as a published band, so check for it before you pay the adult fare twice.
Children, and where the age lines fall
Free under six at both sites that publish prices. €6 for under-18s at San Lorenzo Maggiore and for children at the catacombs. One walking tour sets a minimum age of four, which is the only hard age floor in this set.
The guided-visit surcharge at San Lorenzo Maggiore halves for children aged six to fourteen: one euro rather than two.
The two-euro surcharge nobody mentions
San Lorenzo Maggiore charges €2 per adult for a guided visit, paid on site rather than online, and €1 for children aged six to fourteen. It does not appear on the booking listing, because it is not sold through it.
Between 15 June and 30 September 2026 the complex runs guided visits only, so in that window the surcharge is not optional. Budget eleven euros rather than nine.
The ticket that is good for a year
The catacombs run the only genuine two-for-one in this subject. A San Gaudioso ticket admits you free to the Catacombs of San Gennaro for the following twelve months, guide included. That turns a €13 ticket into two guided visits, on separate days if you like.
It works because both are run by the same organisation. Nothing similar exists across the tunnel sites, which are four separate operators.
ArteCard, Touring Club and FAI
ArteCard brings San Lorenzo Maggiore to €7 and the catacombs to €9. Touring Club and FAI members pay €10.40 at the catacombs. Neither card touches the guided tunnel routes, because those are sold as departures rather than admissions.
Whether a city card pays for itself is a question about your whole itinerary rather than about these four sites, and the savings here alone will not cover one.
What is the cheapest legitimate way underground?
Nine euros at the San Lorenzo Maggiore desk, or $10 booked ahead, opens the Neapolis Sotterrata and the entire complex above it. That is a Roman market street with its shopfronts and its treasury, a cloister, three halls and a museum, and a free audio guide.
It is a genuinely good visit rather than a budget compromise: several travellers rate it above the famous route. If you want the deep quarry system as well, the cheapest fare into that is $21.
Why some prices are in euros and some in dollars
Because they come from different places. The door prices are set by the organisations that run the sites, in Naples, in euros. The tour fares are quoted by booking platforms, and the figures here were captured with those platforms displaying US dollars — which is what a great many visitors see when they search from outside Europe.
Both are shown as they were found rather than converted, because a converted figure is a claim nobody can trace: the rate moves daily, the rounding is not ours, and the number goes stale without anybody noticing. If you pay at a door you will pay euros; if you book ahead you will pay whatever your own platform quotes in your own currency.
The one number worth carrying in your head is the gap. The cheapest way underground is under ten of either currency, and the most expensive guided walk is roughly nine times that — and the difference is almost entirely time spent above ground.
Which of these is worth paying more for?
Three upgrades in this subject genuinely earn their money, and two do not.
- Worth it: the two-euro guide at San Lorenzo Maggiore. The cheapest useful upgrade in Naples.
- Worth it: a small-group cap. Fifteen or sixteen against forty changes how much you hear underground, which is the whole point of being down there.
- Worth it: a full hour below rather than twenty minutes. Two walking tours here charge similar money for wildly different time underground.
- Not obviously: the pizza option. It buys a Margherita or Marinara up to fifteen euros with a soft drink. One traveller with a family of four found it added up.
- Not obviously: the longest walking tours. The two highest fares here buy more street rather than more tunnel.
What happens to your money if plans change?
Almost everything here refunds in full up to 24 hours before the start time, and most listings also let you reserve now and pay later — so a date you are not certain of costs nothing to hold. That is unusually generous for fixed-departure products.
One exception, and it is the cheapest way into the deep system: the official Napoli Sotterranea entry ticket is sold non-refundable. The trade is explicit — a lower fare for a fixed date — and it is stated on the listing rather than buried. If your dates are still moving, the Spanish Quarters route costs the same and refunds.
At the door the rules are different again. The catacombs will not move you to a later slot if you miss yours, and will not refund it. San Lorenzo Maggiore is a walk-up ticket outside the summer window, so there is nothing to cancel: you pay when you arrive.
What sits outside every fare
- Food and drink, on every listing except the two with an explicit meal option.
- Transport, everywhere. Nothing here includes hotel pickup — two listings name its absence explicitly.
- Gratuities, named as excluded on three listings.
- The guided-visit surcharge at San Lorenzo Maggiore.
- Nothing else. There is no reserve fee, no equipment charge and no compulsory extra at any of the four sites.

Frequently asked questions
How much does Naples Underground cost?
Guided tours and entry tickets here run from $10 to $89. At the door, San Lorenzo Maggiore charges €9 and the catacombs €13; Napoli Sotterranea does not publish a door price.
Why is one door price missing?
Napoli Sotterranea publishes no admission figure on its website — it appears only inside its own booking flow. Rather than copy an unverifiable number, none is quoted here.
Is a guided tour more expensive than the door?
Usually, yes. On two of the four sites the question does not arise, because they sell entry and guide as one fare and there is no door alternative.
What is the two-euro charge at San Lorenzo Maggiore?
The on-site guided visit, paid at the desk: €2 for adults and €1 for children aged six to fourteen. It is compulsory between 15 June and 30 September 2026.
Do children pay?
Under-6s are free at both sites that publish prices. Under-18s pay €6 at San Lorenzo Maggiore, and children pay €6 at the catacombs.
Is there a combined ticket?
Not across operators. The one exception is the catacombs, where a ticket opens the second catacomb free for twelve months.
