Butterfly Valley Beach is one of the attractions in the Fethiye area, near Oludeniz. Available in season on a shuttle yacht. It is possible to stay in a bungalow/tent. There are three catering establishments. The beach is small golden pebbles. The depth set is fast. You can't get in by car.
It's a beautiful place. The beach is not very comfortable, there are stones of various sizes, it is inconvenient to enter the water. We were in early October, we didn't see a single butterfly, perhaps it was already out of season.
A small bay between two high cliffs with perfectly blue and clear water at the bottom of which is a white and smooth stone. There are few butterflies at the end of September, but the views and beaches are cosmic. The best beach in Turkey in my opinion.
