Wow, what a museum. There's is so much to see. I would love to return one day because I didn't have…read moreall the time to take everything in. I was there for a good 3+hours. There are sections where the painting takes up the entire wall. Not a mural, but a full painting with an entire scene and details for days. Look up, and you'll see more art. Some art pieces are so large, you can only properly view it from afar. The ceilings are also beautiful. It's all so impressive.
I opted for a timed ticket entry booking for 9am and didn't wait in line for very long. I'd say about 30minutes before it got moving. I was in the earlier crowd, close to the pyramid and can see the security area. Security was swift, but I packed lightly. Of course after using the bathroom and grabbing my audio guide I bee-lined right for the Mona Lisa, knowing it was the most popular painting there. I was able to get right up to the barrier pretty peacefully within 5 minutes of waiting. I heard someone say "well this is quite pleasant" lol. I was surprised too! So definitely get there early because when I returned to this spot later, closer to noon, boy was it packed with tourists groups and people rushing in to try for a good view. I definitely noticed that keeping calm also keeps everyone else around you calm, so don't go running because that might trigger everyone else to run and that's how chaos ensues. Don't push. You've got time, just wait your turn. My friends opted to go on a third party tour and I don't think they were able to get up to the barrier, but they prioritized the in-person guided experience more than anything, so just keep this in mind if you're deciding whether to opt to go on your own or with a group. Everything had English captions which was helpful.
Underground, where the exit is, there are tons of shops. The museum's souvenir shop is quite nice, with cute collaborations. We passed by tons of other cute shops like Pop Mart and Le Petit Souk where I grabbed some cute postcards, and my friend grabbed some flats from VIVAIA. It's a whole mall down there called Carrousel du Louvre. Keep this in mind if you somehow still have energy for it after walking a million steps at the museum lol.
