To reach Letoon, you turn west one kilometer beyond the road from Kinik to Fethiye and Letoon theatre continue 5 km. The history of Letoon is closely linked with that of Xanthos. It is known to have been one of the most important religious centers of the Lycian region. Due to the rising water level, archeological digs have been suspended.

The remains unearthed indicate they belong to the period between the 7th century B.C. and the 6th century A.D. The most important edifice is the Greek style theater which has been preserved until our day. Letoon, nearby, was formerly an important religious cult center where three temples dedicated to Leto, Artemis and Apollo stood in ancient times.
