A UNESCO Biosphere Reserve of cloud forest ridges, traditional mountain villages, and multi-day trekking trails through one of Sri Lanka’s most ecologically rich highland environments – named for the distinctive knuckle-like silhouette of its peaks when viewed from the lowlands. The Knuckles rewards genuine engagement: two days of guided trekking through endemic forest, with village homestay options and the particular satisfaction of a wilderness area that is biologically extraordinary but physically accessible to any moderately fit traveller.
