Sinharaja Rain Forest, Sri Lanka

Sinharaja Rain Forest is Sri Lanka's most precious stretch of primary forest — a UNESCO World Heritage Site and the last viable remnant of the island's tropical lowland rainforest. Covering an area of 18,900 acres, it straddles the Sabaragamuwa and Southern provinces within the south-west lowland wet zone, a region that receives some of the heaviest rainfall on the island.

The forest's boundaries are defined, on three sides, by a natural moat of rivers and waterways that have helped preserve its exceptional biodiversity over centuries. To the east, an ancient footpath near Beverley Tea Estate and the landmark of Denuwa Kanda mark the forest's edge, hinting at the long human history that has unfolded alongside this wilderness.

Natural Boundaries

Sinharaja is enclosed by rivers on three of its four sides, giving it a degree of natural protection that has proved vital to its survival.

• North: The Napola Dola and Koskulana Ganga form the northern boundary.
• South and south-west: The Maha Dola and Gin Ganga border the forest along its southern and south-western edges.
• West: The Kalukandawa Ela and Kudawa Ganga trace the western limit of the reserve.

A Living Heritage

As the last significant lowland rainforest remaining in Sri Lanka, Sinharaja carries an ecological weight that extends far beyond its 18,900 acres. It is a refuge for endemic species of flora and fauna found nowhere else on earth, and its dense canopy, layered understorey, and network of streams create a self-sustaining ecosystem of remarkable complexity. The UNESCO World Heritage designation reflects international recognition of this irreplaceable value.

The ancient footpath to the east, skirting the Beverley Tea Estate and rising toward Denuwa Kanda, is a reminder that Sinharaja has long been known to the people of Sri Lanka — a forest that has been both a resource and a sanctuary throughout the island's history.
