Koycegiz boasts a healthy economy based on local cotton, olive and peanut cultivation. The town’s position, on the Shore of Köycegiz Lake, provides a further source of income from the fish, mostly grey mullet and bass which swim up Dalyan cayi to spawn here. There is a market held every Monday and can be reached via the lake with one of the many co-operative boats that run from Dalyan town between 10:00 to 10:30 and returning at around 18:00.
The lake, the deepest in Turkey, was once a bay open to the sea that became dammed by deposits from the Mountain Rivers.
There is also a lovely forest and a very small sandy beach 800m west of the town. The river, Yuvarlakcay, runs from the west of Koycegiz Lake some 34kms from Dalyan. Near to the source of the river there are trout farms and wooden platforms have been built over the river to take full advantage of its cooling effects, the water remains a constant 10 degrees all year round. To visit Yuvarlakcay, take the main road out of Dalyan towards Ortaca, turn left at the 0400 highway, looking for the Koycegiz/Mugla sign. Take the old road through Eskikoy until you reach the D400 just before the bridge over Yuvarlakcay. Continue on the highway for about 8kms and you will cross a bridge over the yuvarlakcay River and after 700m you will see two cafés on your right. The trout farm is over the bridge and loom up a side road on the left. There are several restaurants further upstream. If you feel energetic after lunch, if’s a rewarding 30 minute walk along (or in) the river to the source..
