The Louvre is amazing. If you are planning on visiting the Louvre be prepared for a full day open to close to experience all the museum has to offer. If time permits on your visit you may want to visit the Louvre over a two day period, so that you may take the time to experience the history. I would get there an hour before opening as the entrance line is extremely long and there is only one entrance. You can not visit Paris without visiting The Louvre.
