Walk up hilly Uzun Çarşı Sokak, the Roman-era road that locals call Slippery Street, to the east of the main square to reach the King's Tomb , a superb example of a 4th-century BC Lycian sarcophagus, which is mounted on a high base and has two lions' heads on the lid.
Antiphellos was a small settlement and the port for Phellos, the much larger Lycian town further north in the hills. The small Hellenistic theatre , 500m west of the main square, could seat some 4000 spectators and is in very good condition. You can also walk to the rock tombs cut into the sheer cliffs above town, that are illuminated at night. The walk is strenuous so go at a cool time of day.
