Sinharaja is a widely spread forest reserve, a national park and a bio-diversity hotspot in Sri Lanka. It carries a great value and is of international significance and has been designated a Biosphere Reserve in 1978 and a World Heritage Site in 1988 by UNESCO.
The virgin and hilly rainforest, part of the Sri Lanka lowland rain forests eco-region, was miraculously saved from the worst of commercial logging by its inaccessibility. The word "Sinharaja" in Sinhala means "Kingdom of the Lion".
This green reserve is only 21 km (13 mi) from east to west, and a maximum of 7 km (4.3 mi) from north to south, but it is a treasure trove of endemic rare species in the world, including trees, insects, amphibians, reptiles, birds and mammals.
