The 20-minute boat ride to the Greek island of Kastellorizo (called Meis in Turkish) gives you a taste of Greece and lets you imagine what Kaş must have been like before the 1923 population exchange, when most residents were of Greek origin.
Isolated from the rest of its country, Kastellorizo has escaped major tourist development and maintains the charm of an island that time forgot. Attractions include a small 12th- to 16th-century crusader castle, notable for its crenellated gray-stone walls; a large blue cave with fine stalactites (speedboat trips can be arranged in Meis Harbor when you disembark); the 1835 church of St. Konstantine and Eleni, which reused granite columns taken from the Temple of Apollo at Letoon in Lycia (usually locked); and a mosque converted into a small museum, which recounts the island's tragic history.
Meis Express (www.meisexpress.com, 242/836–1725) has an office on Kaş's waterfront, with ferry departures at 10:20 am daily; afternoon
trips, returning in the evening, are sometimes available. In either case, expect to pay about 65 TL for a return ticket. You can get a taste of the island in just an afternoon, but if you want more, overnight at one of the island's several hotels or pansiyons.If you're day-tripping, don't be alarmed if the ferry operator wants to hold onto your passport when you disembark in Greece—they process the passports in batches, to speed things up. If you're not comfortable with this, just ask to have your passport stamped while you watch.
