During your next visit to Paris, you will want, of course, to visit the Musée du Louvre, Musée d’Orsay, Tour Eiffel and Champs-Élysées. But there is also a live and free show that you should not miss: The markets of Paris. You will find them in each of the 20 arrondissements on certain days of the week with a rotating formula from one arrondissement to the other as well as in the suburbs. Parisians of all walks of life love to shop and browse among the open-air stalls as merchants cheerfully trumpet — often with humor — the quality of their goods. Rain or shine, the markets start early in the morning and close around 1:30 p.m.
