If you wish to save time and get past the line faster, buy your Louvre tickets at the airport. Alternatively, you could join a guided tour. Once you get through security, you can follow the signs to get to Da Vinci’s Mona Lisa. Afterwards, go see Venus de Milo and Winged victory. The Louvre is an amazing museum, and you will have a great time exploring it. Once you leave the museum, you can make your way to Palais Garnier – the Opera house. They offer guided tours, but you can explore them on your own. The library inside the opera house is one of the best in Europe. Come evening, you can go on a cruise along the Seine River.
