The island of Kastellorizo depends on the ferry service for many things, including the delivery of food and household goods.
Most of the island restaurants and residents visit the Friday fruit and vegetable market in Kas, Turkey. They now have a household and clothing market on Tuesdays.
Several boats leave from Kastellorizo on Friday and Tuesday, but book your ticket early to reserve your place. Passports must be given in the day before to add you to the transit log.
