The best time to explore the Louvre is after 3PM on a Wednesday. It is mid-week and the museum opens until 10PM. Grab a late lunch at the Ellsworth nearby and then enjoy your peaceful seven hours getting lost in this world’s largest museum without rubbing shoulders. It’s very likely you can appreciate the famous Mona Lisa front row and linger as long you want. After dark, take a stroll outside the Louvre pyramids when the lights are up to see the contemporary side of this historic monument.
