The River Seine, often referred to as the lifeblood of Paris, separates the city's historically refined and bohemian areas. It offers riverboat transportation and numerous chances for romantic walks. The riverbanks, designated as a UNESCO World Heritage Site, are adorned with Paris' most iconic landmarks, such as the Eiffel Tower, Notre Dame Cathedral, Musée d'Orsay, Tuileries Garden, and the Louvre.
