和西岱島非常近的一個地方的，離巴黎鐵塔也是不遠的。和西岱島一樣，島上有很多漂亮的歷史建築的，從西岱島過來也是相當的方便的，兩個地方可以同時旅行的

聖路易島和西岱島一樣，是處於塞納河的河中央的小島的，兩島之間是可以相連的，這裏沒有太多著名的建築和景色，反倒是更加生活化一些，逛起來也是挺有意思的

聖路易島（Île Saint-Louis）為巴黎塞納河上的小島，位於巴黎的中心，聖路易這個名稱是從路易九世而來。聖路易橋連接着聖路易島與西堤島。

St. Louis is the smaller of the two islands on the Seine River in Paris, located upstream of Sidai Island. It was an uninhabited island in the early 17th century. By 1664, the island had been filled with ventilated new houses facing the wharf and the Seine. There are many top art galleries and fashion stores on St. Louis. Sidai Island is famous for Notre Dame in Paris and has a lot of tourists. St. Louis Island is much quieter.

Although Sidai is the birthplace of Paris, St. Louis, smaller than Sidai, is connected by an equally small St. Louis Bridge, delicately inlaid in the Seine River. There are also many cafes and flower shops in addition to berthillon ice cream, which emit the flavor of ancient Paris everywhere.

St. Louis in Paris is a peninsula on the Seine River. It is now an urban garden. Flowers are blooming all year round and the environment is very beautiful. Looking at the rows of old buildings across the bank is very stylish. It's a good place for leisure walking and physical exercise.
