Notre dame without towers - waiting time

I was there around 3 pm on a Monday in mid-May and just walked in, somewhat crowded inside but no line to get in.

There was a fairly long line when I went there in February, but it moved pretty fast, approximately 15 minutes or so.

I have visited the Cathedral at least a dozen times and never waited more than 5 minutes to get in.

I have been inside many times now , usually in busy summer season , lines cross crossing the square outside even , longest ever was about 30 minutes ( and that line snaked back and forth several times ) usually it's about 10-15 minutes , even when line looks long . There is no admission fee , so the hold up is simply a bottle beck at entrance , and of course now they look in your bags , but it goes fast , don't be discoraged if you see a line .

Last July we got there early and walked right in. It was amazing.

I was there last week, went in the morning and had about a 10 minute wait to get inside. Not bad at all. Even when the line is longer, it moves pretty fast.

10 or 15 max, I usually walk straight in or nearly. The queue may look long but moves quickly.

Last September we arrived shortly after 8:00 AM and walked straight in.
