Butterfly Valley (Kelebek Vadisi) is a breathtaking Mediterranean "fjord" a few kilometers southeast of Ölüdeniz, near Fethiye (map).
Yachts on day cruises drop anchor here for a swim in the quiet cove, and yachters often come ashore to enjoy the sand beach.
Rustic tree houses rent beds at rock-bottom prices. There are few services—but then, the rustic life is the point here.
If you hike the Lycian Way, you'll pass above Butterfly Valley (Kelebek Vadisi) and get this fantastic view of the valley, the beach and the blue Mediterranean.
