Also known as the Haut-Marais (Northern Marais), the 3rd arrondissement is a buzzing enclave of hip cafes, eateries and shops. Art lovers troop to modern galleries and the Musée Picasso, where many artworks are displayed in a stately 17th-century mansion. The Musée des Arts et Métiers is a top destination for science history buffs. The lively Marché des Enfants Rouge draws crowds to its international food stalls.
