It may not sport the region's finest beaches but its central Teke Peninsula location, mellow atmosphere and menu of adventure activities have made Kaş – pronounced (roughly) 'cash' – an ideal base for forays into the surrounding area. For divers this is Turkey's hub for underwater exploits, with excellent wreck-diving just offshore. A plethora of boat trips, kayaking tours and hikes are also easily arranged from here.
The 6km-long Çukurbağ Peninsula extends west of the pretty old quarter, town square and harbour. At the start of it, you'll find a well-preserved ancient theatre, which is about all that's left of ancient Antiphellos, the original Lycian town. Above Kaş, several Lycian rock tombs in the mountain wall can be seen even at night, when they're illuminated.
Lying just offshore, dominating the harbour view, is the geopolitical oddity of the Greek island of Meis (Kastellorizo), which can be visited on a day trip.
