St, Chappelle and Notre Dame

No combo tickets. Book directly with the sites.

Sainte-Chapelle does offer a combo ticket with the Conciergerie.

Notre Dame Cathedral

If you're unable to get tickets, they do allow entry to the Cathedral. Plan on arriving by 9ish to see the interior without the massive crowds and even longer lines.

The Sainte Chapelle site is easily navigable. If you are a classical music fan, consider getting tickets for the one of the evening concerts. They generally start well before sunset and the light streaming through the stained glass as you listen to the music just makes the whole experience more magical. The concerts are usually short, about an hour, without intermission, so can make a wonderfully romantic end to a day or start of a special evening. The pieces are usually pretty accessible “war horses”: Back in 2002 we heard the Bach Violin Sonata #1 in G minor, #1, a favorite practice piece of my violinist husband’s, and he’s never forgotten that night…

If you plan to attend a concert at Sainte-Chapelle, look into the Passion Monuments Subscription. In addition to reduced price tickets for select concerts, you get free entry during the day to Sainte-Chapelle as well as several other monuments in Paris and throughout France, such as Arc de Triomphe and The Pantheon and, in many cases , skip the security line. A really good value.

Hi! For Sainte-Chapelle, you'll need to buy tickets/reserve a time slot] at least a week in advance (tickets for June at out now!): https://www.sainte-chapelle.fr/visiter/informations-pratiques You'll need to arrive in the queue at least 30-45 minutes ahead of your reserved time slot, and the wait time could be 1 hour (or even longer on a really busy day). I recommend visiting earlier in the day because the later in the day you visit, the higher the risk of longer wait times and the queue can get quite backed up throughout the day. Sainte-Chapelle is within the perimeter of the Palace of Justice, which includes the courthouse/the supreme court for criminal and civil cases, so in comparison to other monuments, security is much tighter and the entrance process takes much longer.

For Notre Dame, reservations are not required, but since you'll be visiting during peak season, I would strongly recommend reserving a time slot in advance. Especially if visiting Notre Dame is super important to you, it's better to reserve a time slot just in case, or else it's possible you'll have to wait a long time to enter (it could be as long as a few hours in peak season).

Time slots can be reserved on Notre Dame's free online reservation system for dates up to 2 days in advance: https://resa.notredamedeparis.fr/fr/reservationindividualelle/tickets.

• The first batch of new time slots is released at midnight (Paris time), for the date 2 days ahead. For example: At midnight (Paris time) on October 1st, time slots are released for October 3rd. Any dates beyond October 3rd will automatically be greyed out/appear to be full.
• A second batch of new/additional "same day" time slots are released 4 hours in advance. For example: At 5:00am (Paris time), new time slots are released for 9:00am for that same day. At 5:30am, new time slots are released for 9:30am, etc. However, there are certain hours when no time slots are ever offered, therefore no new time slots are released 4 hours in advance of those hours. For example: No time slots are offered for 12:00pm, therefore no new time slots will be released at 8:00am.

Time slots are offered in 15 minute intervals. This is meant to help spread out the flow of visitors coming in/out, but it doesn't mean that you're limited to only 15 minutes to visit!

• Monday to Saturday, time slots are generally offered between 9:00am and 10:45am and between 1:00pm and 4:00pm. On Thursday, additional time slots are generally offered between 7:00pm and 9:00pm.
• On Sunday, time slots are generally offered between 1:00pm and 3:00pm.

Not every time slot is offered every day. Which time slots get released/are available for each day is all dependent on what's happening at Notre Dame on that day, and who else is scheduled to attend (ie. pilgrim groups, school groups, international diplomats/government officials, etc.)

For the lowest crowds, I recommend visiting on Tuesday, Wednesday or Thursday before 10:30am. But please note that for the unforeseeable future, the ambulatory (the back half of the cathedral) and the back chapels don't open until 8:45am during the week.

Or, if you're available on Thursday evening, I recommend visiting between 7:00pm and 9:00pm (the ideal time to visit is around 8:30pm). This is generally a more peaceful time to visit! Notre Dame is open until 10:00pm on Thursday, but everyone has to be out before 10:00pm and the ambulatory (the back half of the cathedral) and the back chapels close at 9:30pm, so I recommend entering at least by 9:00pm.

Don't use GetYourGuide, or any other third-party site. Only reserve time slots directly on Notre Dame's official online reservation system. Reservations/time slots obtained from anywhere else are fake, and they will not be accepted at entry (and never pay to visit the main floor of Notre Dame and/or to attend Mass/liturgical services, it's always free!).
