Originally used for cattle grazing, Île Saint-Louis was formally developed under the orders of King Louis XIII in the early 17th century. Connected to the Left and Right Banks by four bridges (the Pont de la Tournelle, the Pont Marie, the Pont Sully, and the Pont Louis-Philippe) and to Île de la Cité by the Pont Saint-Louis, the island is at once easily accessible but also an unspoiled slice of historical Paris. Long a retreat for the city’s wealthy, Île Saint-Louis still retains its aristocratic allure, and its narrow streets and traditional buildings make it a tranquil place to stroll.
Walking and bike tours are an excellent way to soak up the peaceful atmosphere and admire views of the UNESCO-listed Banks of the Seine and neighboring Notre Dame (located on the eastern edge of Île de la Cité). Seine River cruises also reveal another picturesque perspective on the island.
