The Prince's Islands are an amazing escape away from the city; a place where "time stood still" in the best possible way. Almost all of the beautiful 20th and 19th century Victorian and Art Deco houses have been preserved, and all forms of automobiles are banned on the island, creating an amazingly tranquil and serene atmosphere. Great for biking (renting one for the whole day costs just 10 TL), walking, and discovering Istanbul's historical diversity as many of Istanbul's historical Greek, Armenian, and Jewish minorities once lived here (and still continue to do so).
