Peak Wilderness Sanctuary

Overview

Peak Wilderness Sanctuary is the 224-square-kilometre protected mountain forest surrounding Adam’s Peak (Sri Pada), encompassing the highland ecosystem that bridges the lowland rainforests of Sinharaja with the central mountain chain. The sanctuary is a critical biodiversity corridor — connecting the wet zone forests of the southwestern lowlands with the central highlands in an unbroken ecological continuum — and it harbours an extraordinary concentration of endemic species that includes rare leopards, sambar deer, purple-faced langurs, Sri Lanka whistling thrush, and hundreds of endemic plants. The sanctuary also contains the streams that form the headwaters of multiple major Sri Lankan rivers, making it one of the island’s most important ecological and hydrological assets. Most visitors experience the sanctuary only as the setting for the Adam’s Peak pilgrimage, but its full biological richness extends far beyond the pilgrimage routes.
