Paris is one of those cities one can never tire of. It offers so much for every type of traveler, at all levels. A first-time traveler will of course take in the top sites, from the Louvre, the Eiffel Tower, a river cruise along the Seine and some shopping districts, such as the Marais. After a couple of visits, you’ll dig much deeper, learn the very efficient metro and discover cafés, parks and smaller museums and perhaps venture further afield.
