In case you’re not that motivated for the long queues of the Musée d’Orsay, consider the Musée Marmottan Monet. Impressionism can be found here as well, although at a smaller and more personal scale. It was an art collector called Paul Marmottan who turned a former hunting pavilion into a place to store his favorite artworks and the museum still has this look and feel.
The museum made me re-like impressionist art, which kind of had become a cliché to me simply because of its omnipresence in Paris. And although it is hard to compete with the magnificent Orsay, they do have an interesting permanent collection and varying temporary exhibitions.
I was surprised to see how many super well-known paintings of Monet, Cézanne and the likes are kept here, as well as the (first, if not only) female impressionist painter Berthe Morisot. Their current temporary exhibition is dedicated to Camille Pissarro, who was at the cradle of the impressionist movement.
The Marmottan Monet is located in the posh 16th arrondissement. An area that I never really go to, but occasionally its fancy avenues and Jardin de Ranelagh are a nice change from the busy city center.
