An often overlooked ancient city is within easy reach from Fethiye. I had overlooked it before, but in 2016 visited it, first taking a minibus to a village, then renting a taxi. A notice is clear (as usual rambling at some points):

“The ancient city of Cadianda is located [at] about 24 km. distance from Fethiye. To reach Cadianda follow the village road between Yeşil Üzümlü town and Ortaköy village, and then turn south to the 8 km. long stabilized forest road at Ecebeli locality.
Cadianda’s name was read as “Kadawanti” in the Lycian inscriptions. Because of the suffix “-nd”, it can be said that the history of [the] settlement dates back to 3 thousand BC. However, the oldest remains of the ancient city that have survived on the surface do not go [back] more than [to] the 5th century BC. Part of the ruins of city walls surrounding Cadianda, tombs and some of the inscriptions are the only remains dated to the earliest period. The city is surrounded by walls which were rebuilt many times due to the topography and the steep slopes of the land. Mostly [the] south parts of the wall still remain. Polygonal city walls from the Hellenistic Period formed retaining walls of the ancient theatre and show a high quality workmanship. The Hellenistic Theatre was repaired and used again in the Rpman Period and can be reached by the side of the Cadianda city walls. Leaning on the southern slopes of the acropolis, despite the collapse, the theatre reflects its former glory. [The] necropolis area is located in the southern part of the city outside the fortress walls. Other significant structures with the majority of the number [meant is: of which there are a lot] are cistern ruins. Four major inter-connecting cisterns which are located under a wide field at the eastern part of the stadium, shows us the significance of the water shortage problem in the ancient city. Most of the remaining ruins in Cadianda belonged to the Roman Period. Even though there have been settlements until the 7th century AD, remains of the late period are not intense, apart from those you can see. Baths, running track, the Agora, ruins of a temple belonged to an unknown God and traces of intense civil construction reveal the identity of a full city and ancient settlement of Cadianda."
