Amazing but Overwhelming
Yes, the Musee de Louvre is fantastic, breathtaking, enormous, classic, a Paris staple, etc. but truth it without a guide or at least an audio guide one can get lost in the myriad of ancient items. We arrived hungry and settled for a snack inside - not a good idea. The selection was minimal and unappetizing. We then proceeded to Italian paintings and spent about 2-3 hours admiring the work of Davinci, Botticeli, Verrocchio, etc. By the time the museum we finished in the Italian wing, we only had a few hours left to see the rest of the museum. We rushed through as much as we could, barely scratching the surface of the many treasures.
Point of the story is, if you only have one day and only have a rudimentary understanding of art and its significance I'd recommend a guided tour to take you to the main attractions and give you a good understanding of what you are looking at. Nothing is in English as in some other museums so gear up your French.
The February lines were a breeze!
