Le Carrousel du Louvre

What looks to be a fashionable mall is a corridor to the least-crowded entrance into the Louvre.  You can buy tickets at the Tabac on the lower level and quickly enter - no lines and no waiting!  

To get there take Metro Line 1 and exit at the Palais Royal--Musee du Louvre station, and never leave the covered area going from one underground area to the next.  Just follow the signs to Carrousel du Louvre. 

In the distance you can see the Pyramid
