A UNESCO Biosphere Reserve of dramatic cloud-forest ridges, endemic wildlife, traditional mountain villages, and trail systems offering some of the finest trekking in Sri Lanka – named for the knuckle-like silhouette of its peaks when viewed from the lowlands, and home to dozens of endemic species and rural farming communities whose lifestyles have remained largely unchanged for generations. The Knuckles rewards multiple days of exploration with continuously varying landscapes, genuine biodiversity, and the particular satisfaction of a wilderness area that most Sri Lanka visitors never reach.
