Beyobasi is a small town near Köycegiz reached by going east and just after it,the first turning on the left from the main road takes you to the Yuvarlakçay river. This river energetically tumbles down from the mountains and provides a wonderful cool and refreshing retreat from the summer heat. Sometimes it is nice to escape from the summer heat. If you want to, you could try a rafting adventure or a cold swim here, but beware – very few people can stay in the icy cold water more than a few seconds. If it's something more peaceful you want, try the restaurant and eat a tasty meal beside the fast flowing water. There is a trout farm along the river and you can buy smoked or fresh trout here.

Ekincik Bay is a little resort accessible by car or by boat. With its natural environment and its lovely beach, it is a favourite stopover for visiting yachts.
