Located within the borders of Ölüdeniz town in the Fethiye district of Muğla province, Butterfly Valley lies at the foothills of Mount Babadağ — one of the 100 mountains proposed for preservation as a world heritage site due to its endemic species. On February 8, 1995, it was declared a First-Degree Natural Protected Area and has since been closed to all types of construction. The valley, surrounded by steep rock walls reaching up to 350 meters, derives its name from the more than 80 species of butterflies it hosts, most notably the Jersey tiger butterfly. A stream, sourced from a waterfall in the Faralya neighborhood and cascading from a height of 50 meters, flows through the valley and empties into the Mediterranean Sea. The valley’s unique geographical structure, flora, and fauna make it a point of interest for scientists, especially botanists and entomologists, for research and fieldwork. It also draws attention from national and international environmental organizations and ecological groups. The history of Butterfly Valley dates back to the 4th century BCE. Remains of the ancient Lycian settlement known as "Perdicia" are located just above the Butterfly Valley Canyon. The nearby village has traditionally been called "Faralya," and its modern name is Uzunyurt. The culture of terrace gardening, developed by shaping the slopes into stepped fields, has continued from Byzantine and Greek civilizations through to the late Ottoman period and still exists today.
