Even if you don't identify as an art lover, it'd be a shame to come all the way to Paris and not even bother to visit its museums. The Louvre is a must, and don't pass up smaller museums like the Musée National Picasso.
It may seem morbid to devote a full day to hanging around a cemetery, but Père Lachaise feels more like an overgrown leafy park that just so happens to also house the dead. Here you'll find famous names like Gertrude Stein, Oscar Wilde, Proust, and Jim Morrison alongside unknown Parisians with unusual tastes in tombstones. Père Lachaise sits on 110 acres with 69,000 burial plots, so bring your walking shoes.
Everyone wants to eat well in Paris, so don't miss department store food halls like Le Printemps du Goût in Printemps de l'Homme, the food court in Galeries Lafayette, and Grande Epicerie in Bon Marche. Stuff your face with pastry, and stock up on wine and sweets to take back home.
