Peak Wilderness sanctuary is a natural reserve in Sri Lanka. It is the third-largest (by area) of the 50 sanctuaries in the country.

"Sri Pada" Peak Wilderness sanctuary is a tropical rain forest that spreads over a land of 224 square kilometers around the Sri Pada (Adam's Peak) mountain. A huge forest area that belonged to the Peak Wilderness was cut down and cleared during the British colonial rule in Sri Lanka (1815-1948) to gain land for the massive tea estates which are still functioning in Nuwara Eliya district. The remaining portion of the Peak Wilderness was declared a wildlife sanctuary on October 25, 1940.
