We got to the beach by boat, which departs from Oludeniz beach. It is the ticket sale point that is needed, which is closer to the entrance to the beach and further from the sea. Departs at 11, at 13, at 16 there and at 12, at 14, at 17 o'clock back. (The schedule may change) It costs 150 lire per person round trip. Swim in one direction for about half an hour. We liked everything, both on the beach and the way to get there- inexpensive and convenient)
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.
