Sinharaja Forest Reserve is Sri Lanka’s last surviving viable area of primary lowland tropical rainforest and a UNESCO World Heritage Site of global ecological importance. Over 60% of the endemic bird species of Sri Lanka are found within Sinharaja, including the Sri Lankan blue magpie and the green-billed coucal, making it the island’s premier birdwatching destination. The forest’s interior is a world of biodiversity – ancient trees draped in moss and orchids, streams alive with endemic fish and amphibians and the constant orchestra of insects, frogs and birds.
