You should see the tiny Mediterranean fishing village of Üçağız, 39 km (24 miles) east of Kaş by road (map), before it's spoiled.
The best way is on a boat excursion from nearby Kaş, or from Çayağzı near Demre-Myra.
Okay, Üçağız (EWCH-ah-uhz, "Three Mouths," for the three rivers that debouche here) is no longer the perfectly authentic little Mediterranean seaside hamlet that it was in 1990, but the government is limiting new building so it's still pretty nice.
Old village houses are interspersed with tall stone Lycian tombs over 2000 years old, and the marble ruins of a Roman "sunken city" still glisten beneath the pellucid waters of the Mediterranean just offshore.
In 1990 there wasn't even a decent road into the place. Most people came by boat then--and they still do, because the road, although paved, twists through the hills for 19 km from the coastal highway.
Whether you start from Kaş or Çayağzı, or whether you drive to Üçagiz and join a boat tour there, you'll also be dropped at the pristine village of Kaleköy (Castle Village) to walk its streets, have tea in its cafés, and see its little fortress.
Üçağız has some pretty good restaurants for the yachters who moor here for lunch, and a few small, simple lodging-places, but the beds tend to fill up in summer, so if you want to stay here awhile your best bet is to come on a day-trip, ask around, find a room, make a reservation, and come back with your stuff.
