The Louve

It's Louvre. There are several entrances to the museum. I usually use the Carousel mall entrance and have never waited more than 10 minutes to get through security. Once under the pyramid there are a dozen machines for tickets and several manned stations.

If you have a museum pass I believe you can use the Richelieu entrance although that policy changes from time to time. The long lines are security lines, not ticket lines.

We came in from the subway ,walked through the turnstile , purchased 2 tickets and were in in 10 minutes .it was in sept . Went in the morning

I had a museum pass for the Louvre, there were two lines, one for ticket/pass holders and one to buy tickets. The pass holders' line took ten minutes or less, then everyone merges into security lines, which went quickly (maybe five minutes there).

I went last Oct, got in the Museum Pass line about 30min before it opened, I was #5 in line, there was already about 25 or so in the regular line. This was at the main Pyramid entrance, by 9:00 there was about 100 people in the regular line and about half in the Museum Pass line. Once the doors opened at 9:00, went through security pretty quick (opened my satchel, a quick look, & done) and followed the signs to the Mono Lisa. When I arrived there, there was less then a dozen people in the room. Got great photos and then headed through the museum, many rooms to myself with security before the crowds started. Passed Winged Victory on the way to the Mona Lisa and got great pictures there as well with no one around it.
Enjoy.

I know this is heresy, but I'd consider skipping the Louvre in favor of "smaller" museums. The hordes of people make for an unpleasant experience and you have to wait in line to see the Mona Lisa while the hundreds of people in front of you take their selfies. It's not a fun trip and you really don't have much of an opportunity to appreciate the art. Instead consider the D'Orsay and Rodin, both are fabulous, less crowded and pretty close to each other. We didn't get to the Orangie, but wish we had, it's also supposed to be very good.

If you do go, by all means purchase a Museum Pass. We were there in mid-April and the Museum Pass allowed us to walk right in, no waiting at all.

It may be that there are no "easy ways to get into the Louvre without the long lines."
The Louvre is one of the largest museums (physically and in terms of the collection) in the world.
And Paris is one of the heavily visited cities by tourists.
There are lines to buy tickets, which can be avoid by having some kind of Pass.
But there are also security lines that cannot be avoided even if you have a pass.
Currently it's open Wed. & Fri. nights, when there are fewer crowds.
You can get into a private tour that will bypass some of the above but then you'll be led around with fifty other people and get in the way of those of us trying to see the paintings as independent travelers.

There are some lesser visited parts of Louvre without the elbow to elbow crowds , avoid seeing the Mona if you wish to avoid crowds.

I would never miss a chance to visit the Louvre, but it pays to do a bit of research beforehand and decide which sections would be of most interest to you personally, not just cramming in to see the few well known exhibits! O

pat is right, I went to the Louvre at 9am and had the classical galleries to myself - really, no one else was there- for about 40 minutes while everyone else was at the Mona Lisa (I got to her later).

5 years ago I went to the Louvre on a Friday late afternoon in June and had the place nearly to myself, so last month I thought I would have a similar experience on a Wednesday. I got there about 6.30 (there was a short security line at the Pyramid entrance - one line for everyone). Boy was I wrong. A lot of tourists had figured it out. There still wasn't a lot of crowding but the noise level was very disturbing. Visitors, some teens (to be expected) but mostly adults, and in several languages including French, were all speaking in louder than "indoor voices" and I could even hear guards conversing across the room. I lasted about an hour.

If you are talking about the pyramid noise level, Chani, you're right. It's a known problem, particularly troublesome for the people who sit in the info kiosk all day. I.M. Pei has beautiful designs, but they aren't always practical.

No. Sadly, I am talking about the galleries in the museum.
