Paris is usually associated with its world famous sites, like the Champs-Élysées, Arc de Triomphe and the Eiffel Tower. It's also a wonderfully walkable city. Strolling along the walkways near the Seine River and traveling across its many bridges is a definite highlight for any tourist, but especially for visitors who want to enjoy amazing views of the City of Lights at nighttime. Cobblestone side streets and lanes that are blocked off to auto traffic make it possible to explore the authentic side of Paris without having to dodge honking vehicles. The city's grand parks and gardens add to the allure for walking enthusiasts. Meanwhile, the Paris Metro makes it possible to get between arrondissements quickly without hailing a taxi.
