Sinharaja: An acclaimed fascinating natural wonder in an Island

On an island of just 65,000 square kilometers lies one of the world’s most fascinating natural wonders—Sinharaja.

It is Sri Lanka’s last remaining viable remnant of primary tropical lowland rainforest.

Spanning 8,864 hectares, this UNESCO World Heritage Site is a living museum of biodiversity and a must-visit destination for nature lovers.

It was designated by the UN as a Natural World Heritage site in 1988 and in the same year was named as a World Biosphere Reserve.

Around 60% of Sinharaja’s trees are endemic, including many rare and precious species found nowhere else on Earth.

The rainforest is alive with endemic wildlife, particularly birds, and shelters more than half of Sri Lanka’s endemic mammals, butterflies, reptiles, insects, and amphibians.

Ranging in altitude from 300 to 1,170 meters, Sinharaja consists of 6,092 hectares of Forest Reserve and 2,772 hectares of Proposed Forest Reserve.

Its narrow strip of undulating terrain is interlaced with ridges, valleys, and a maze of sparkling streams, creating a landscape both scenic and scientifically significant.

The United Nations describes Sinharaja’s flora as a relic of Gondwanaland, making it a vital site for the study of continental drift and the processes of biological evolution.

Geologically, the reserve is equally fascinating, as it sits within the transition zone of Sri Lanka’s southwestern and highland rock groups, with the notable Sinharaja basic zone adding further scientific intrigue.

A walk through this pristine forest is like stepping into an ancient, untouched world.

For eco-tourists, researchers, and adventurers alike, this rainforest is not just a destination—it is a reminder of the delicate balance of nature and the importance of preserving it for generations to come.
