In the form of a narrow canyon stretching over around 3–4 km (1.9–2.5 mi), the valley's steep walls are 350–400 m (1,150–1,310 ft) high.

In the middle of the valley, a creek runs, carrying water from a spring in nearby Faralya village to the sea.

A road from Ölüdeniz to Uzunyurt, which is part of the Lycian Way Ultramarathon route, runs atop the rocks around the valley.

[7] It is accessible by shuttle boat service from Belceğiz Beach of Ölüdeniz in 5–7 km (3.1–4.3 mi) distance,[4] operating hourly at daytime.

[2][6][8] Designated a nature reserve as protected area of first category on February 8, 1995, any type of construction in Butterfly Valley is strictly prohibited by law.
