How far in advance are Notre Dame tower tickets released?

If you are just visiting inside Notre Dame, you really do not need tickets. If you want to climb the bell tower, booking information is here:

Towers specifically.

Maybe I’m not looking carefully enough but I’ve been on the information page and cannot find information about how far in advance tickets for the towers are made available. The current calendar shows tickets available through April 6th but I’m trying to find out whether 75 days in advance is a set window or whether ticket release is variable.

From the massively useful reddit thread linked elsewhere on the forum: "The exact date/time of when the next block of time slots/reservations get released for the bell towers has been slightly inconsistent, but as of now generally speaking, around the 3rd week of the month, the next block of time slots/reservations get released, for dates/times 50-80 days out."

The advice given is to book 3-4 weeks in advance for peak times. Good luck!

Thank you, Archer! That information tracks with what I saw today— it’s mid week the 3rd week of the month and I’m seeing availability ahead for 75 days. I will check back periodically but if they continue making updates on the 3rd week of the month the June date I’m looking for will most likely become available the 3rd week of April (if they only book out a maximum of 80 days my date won’t be made available in March.)

Thanks for locating the earlier thread. I did search the forum before posting this but probably didn’t include the correct key word combination.

Hi! Someone above already quoted part of my response from my Reddit thread,

"The exact date/time of when the next block of time slots/reservations get released for the bell towers has been slightly inconsistent, but as of now generally speaking, around the 3rd week of the month, the next block of time slots/reservations get released, for dates/times 50-80 days out."

...but I realize I may not have explained it very well!

So for example: Around the 3rd week of February, the block of time slots/reservations will get released for dates/times between the 2nd week of April until the 1st week of May. Then, around the 3rd week of March, the block of time slots/reservations will get released for dates/times between the 2nd week of May until the 1st week of June. And so on.

But which exact dates fall within the 3rd week of the month can vary between months, so another approach is to check the website/reservation system between the 15th-20th of the month, for the next block of time slots.

Due to the limited number of time slots available, I strongly recommend buying tickets at least 2 weeks in advance (3-4 weeks in advance during peak season), especially if you have a specific date/time of when you want to visit!
