Reached only by taxi boat or by walking the (extremely rocky) Lycian Way Trail, Butterfly Valley is a hidden gem of a beach and one of Turkey’s best-kept secrets. Its name comes from the rare species of more than 60 different types of butterfly that were, up until fairly recently, the valley’s only inhabitants. The steep-sided valley is filled with rich flora and fauna and lush vegetation that shelters the white-pebble coves; from here you can take a dip in the azure ocean and splash around in two small waterfalls.
