Louvre tips

Best times to visit without queuing is later on the late night openings ie Wednesday and Friday when the Louvre is open to 10pm.

We walked straight to the ticket purchasing desk, after we had our dinner then walked right on in. Of course the Louvre is massive, so you can either just target a few places you want to visit or wander randomly.

Personally I find museums of this size overwhelming and like to reduce my visit to bite sized chunks, especially when travelling with a 9 year old.
