Knuckles Range

From the right vantage point near Kandy, the Knuckles Mountain Range genuinely resembles a clenched fist pressed against the horizon, five main peaks rising like knuckles above the surrounding hills, a resemblance British colonial surveyors noticed and named accordingly.

Named for Its Silhouette

The Knuckles Range takes its widely used English name from an observation made by British surveyors during the colonial era, who noted that the range’s series of prominent recumbent folds and peaks, viewed from certain angles, closely resembled the knuckles of a clenched fist. Locally, the range is known as Dumbara Kanduvetiya, “mist-laden mountain range,” a name that speaks to the near-constant cloud cover draping its higher elevations. Older Sinhala names for the area, including Giri Divaina and Malaya Rata, and archaeological evidence pointing to an ancient Yaksha settlement, suggest the range has held human significance for a very long time, well before its more recent English name took hold.

An Astonishing Concentration of Biodiversity

What makes Knuckles genuinely remarkable isn’t its size, at roughly 18,500 hectares it constitutes barely 0.03% of Sri Lanka’s total land area, but its ecological density. Isolated from the island’s central highland massif by the Dumbara Valley, the range has developed as a kind of self-contained climatic microcosm, its varied elevations and rainfall patterns supporting montane cloud forest, tropical rainforest, riverine forest, and unique grassland ecosystems called Pitawala Patana, sometimes all within a single day’s hike. That isolation has produced relict, endemic species found nowhere else on the island: more than 34% of Sri Lanka’s endemic trees, shrubs and herbs grow exclusively within these forests, and surveys have recorded 64% of the range’s amphibians and 51% of its reptiles as endemic to Sri Lanka.

Ongoing field research continues to turn up genuinely new discoveries here. Scientists working in the range have identified previously unknown amphibian species, including one of the smallest amphibians recorded in the country, and a newly described snake species named Aspidura ravanai, Ravana’s rough-sided snake, a fresh scientific find tying directly back into the region’s older Ramayana-linked folklore.

Visiting Tips

• Hire a licensed local guide, given the range’s varied terrain, changeable weather, and limited official signage on many trails.
• Pack for multiple climate zones in a single day, conditions can shift from humid rainforest to cool, misty cloud forest as elevation increases.
• Visit during the drier months for the most comfortable hiking conditions and clearest views.
• Combine with a stay at one of the small eco-lodges or homestays in villages bordering the reserve for a fuller immersion in the area.

A Living Laboratory

Knuckles functions less like a conventional tourist attraction and more like an active research site that happens to welcome visitors. New species discoveries here aren’t historical footnotes, they’re an ongoing process, with researchers regularly adding to the range’s already extensive catalogue of endemic life. That living, still-unfolding scientific significance gives a hike through Knuckles a different character from many of Sri Lanka’s more thoroughly documented natural attractions: there’s a genuine, if small, chance that something encountered along a remote trail hasn’t yet been formally described by science at all, a rare quality for any accessible hiking destination anywhere in the world.
