During the summer months the Princes’ Islands are popular destinations for day trips from Istanbul. As there is no traffic on the Islands, the only transport being horse and cart, they are incredibly peaceful compared with the city of Istanbul. They are just a short ferry ride from both the Asian and European sides of Istanbul. Most ferries call in turn at the four largest of the nine islands: Kınalıada, Burgazada, Heybeliada and finally Buyukada. In spring and autumn the islands are quieter and more pleasant, although the sea can be rough in spring, autumn and winter, and the islands are sometimes cut off from the outside world when the ferry services are cancelled due to storms and high waves. During winter, with the addition of the biting cold and the strong winds and the resulting ferry cancellations, the islands become almost deserted.
