Il Louvre it is one of the most beautiful museums in the world which boasts 35.000 works inside. It has been estimated that to visit this wonderful museum well, you would need well 9 months
I advise you to limit yourself to a few sections, and a few hours, to avoid that you go out discontented and dissatisfied for not having seen everything. If you go to Paris the Louvre stage is more than a must, so you have to budget for it. The cost of the entrance ticket is not high as if you want to visit only the permanent exhibition you will have to pay € 8.50 which goes up to € 13 if you want to visit the temporary exhibitions as well. Two small tips could be useful to save a little something: on Wednesdays and Fridays after 18pm, admission is discounted to € 6 for the permanent exhibition and € 11 for admission including temporary exhibition.
La first Sunday of the month admission to the Louvre is free. Another little tip for those under 26 is to pay a visit to the museum on Friday night because after 18pm, until closing time, that is 22pm, the museum is free
The stop to reach the museum is Palais Roya-Musee du Louvre, but they also exist for the Paris transport different tricks and transport cards to save.
