Visit the Musee D'Orsay
When people think of Paris museums, the Louvre is the first to come to mind. But D'Orsay is the best museum the city has to offer. Whereas the Louvre's collection is spread across the enormous palace and takes days to explore, D'Orsay is compact and can be completed in a morning. The building itself is beautiful, a converted train station, and it's packed with recognizable pieces from Monet, Van Gogh and others. If you're into museums, the Louvre is still definitely worth seeing. But if you're making only one art-related stop in Paris, make it Musee D'Orsay.
