The short answer
Entry to Notre-Dame is free and always has been. A free timed reservation on the cathedral’s own website moves you past the general queue and opens two to three days ahead. Only the Bell Towers (around €16, online through the Centre des monuments nationaux), the Treasury (around €12) and the Archaeological Crypt (around €9) carry their own tickets. A guided tour buys you a guide and sometimes reserved access — never entry itself.
The single most important thing to know about visiting Notre-Dame de Paris is also the most misunderstood: entry to the cathedral is free. There is no admission ticket, and there never has been. What confuses visitors is that a few specific experiences are ticketed, and that plenty of websites would happily sell you something you can get for nothing. Here is how it actually works in 2026.
Free entry and the reservation system
Anyone can walk into the nave of Notre-Dame free of charge. To manage the crowds since the December 2024 reopening, the cathedral runs a free, optional timed-reservation system on its official website. Booking a slot lets you skip the general queue — a real advantage from April to October, when walk-in waits can stretch from 30 minutes to three hours. Slots typically open only two to three days in advance, so set a reminder rather than trying to book weeks ahead.
What actually costs money
Three parts of the site carry their own, separate tickets:
- The Bell Towers — reopened in September 2025. A 422-step climb to the chimera gallery and the great bells, around €16, booked online in advance through the Centre des monuments nationaux. There is no ticket counter on site.
- The Treasury — the reliquaries, sacred vessels and the Crown of Thorns, around €12, paid at the entrance inside.
- The Archaeological Crypt — Roman and medieval Paris beneath the parvis, around €9, with its own entrance and schedule.
Where guided tours fit in
A guided tour is a paid service, but you are paying for the guide and, on many tours, for reserved or coordinated access — not for entry itself. Because Notre-Dame now restricts spoken guiding inside the cathedral, most tours give you the full story outside on the parvis before taking you in. In peak season, a reserved-access tour can be the easiest way to avoid the queue without gambling on a free slot. See our full rundown of hours, access and getting there on the visiting guide, or compare the Notre-Dame Cathedral Tours listings side by side.
What each ticket costs, side by side
| What | Price | Where to book | Worth it if |
|---|---|---|---|
| Cathedral nave | Free | Official Notre-Dame site (timed slot, optional) | Always — this is the visit most people mean |
| Bell Towers | Around €16 | Centre des monuments nationaux, online only | You want the chimeras, the bells and the rooftop view |
| Treasury | Around €12 | At the entrance inside the cathedral | Reliquaries, vestments and the Crown of Thorns interest you |
| Archaeological Crypt | Around €9 | Own entrance on the parvis | You like Roman and medieval city history |
| Guided tour | From $24 | Booking platforms | You want the building read to you, not just seen |
How the free reservation actually behaves
The system is simple once you know its rhythm. Slots are released on a rolling basis, usually two to three days out, and they are free, so they go quickly in high season and sit half-empty in February. You choose a fifteen-minute arrival window rather than a fixed minute, and you show a QR code at the reserved-entry side of the parvis. Missing your window is not fatal — you rejoin the general line, which is exactly where you would have been without a reservation.
What the reservation does not do is guarantee an empty cathedral. It moves you past the queue, not past the crowd. On an August Saturday the nave is full whether you waited outside or not, which is the real argument for an early slot rather than simply a reserved one. The best time to visit goes into the hour-by-hour detail.
Avoiding the scams
Because the cathedral is free, the resale market around it is murky. Two rules keep you clear of it. Use the official Notre-Dame and Centre des monuments nationaux websites for free reservations and tower tickets, and use reputable booking platforms for guided tours. Anything that sells you “entry to Notre-Dame” as a product, with a price beside it and no guide attached, is selling you something you already have.
The subtler version is a listing that bundles free entry into a price and calls it “skip-the-line admission.” That is not always dishonest — some tours genuinely hold reserved group access, which has real value in July. The test is whether a guide comes with it, and whether the reserved access is spelled out rather than implied. If you are unsure what is and is not included, our FAQ page answers the questions travellers ask most.
Three ways travellers get this wrong
- Booking a tower ticket at the cathedral. There is no counter on site. If you did not book online, you are not climbing that day.
- Reserving weeks ahead. The slots are not there yet. Set a reminder for three days before and book the moment your window opens.
- Assuming a tour includes the towers. None do, and none can — the ascent is sold separately and self-guided. See how to choose a Notre-Dame tour for what tours do include.
Do you need a tour at all?
Often, no — and that is worth saying plainly on a page that also lists tours. If you have a free reservation, an early slot and half an hour of reading behind you, the cathedral gives you everything a walk-through can give without a guide. Entry is free, the interior is open, and nobody stops you looking.
What a guide adds is the reading. Which portal figures are medieval and which are Viollet-le-Duc’s. What burned in 2019 and what was carried out. Why the buttresses take that shape, and why the walls could become glass because of them. That is the thing free entry does not hand you, and it is what the listings actually sell. If you would rather do it yourself, our interior highlights guide is written to be read on the parvis.
What to do on the day
Bring the smallest bag you can: large bags and luggage are refused at security, and there is no cloakroom. Cover your shoulders and knees — this is an active place of worship, and security enforces it. Arrive fifteen minutes before your slot rather than on the minute, because the queue for reserved entry is short but not instant. And if a service is under way, tourist circulation pauses; the events page explains how the liturgical calendar overrides the tourist timetable.
