Sinharaja Forest Reserve is a national park and a biodiversity hotspot in Sri Lanka.  It  is  of international  significance  and  has  been  designated  a Biosphere  Reserve and World  Heritage Site by UNESCO in 21st October 1988. Sinharaja is the last remaining relatively undisturbed remnant of tropical humid evergreen forest in Sri Lanka. This Forest covers an extent of an approximately 11.187ha. From east to west the length of the forest is 21 K.M’s.  Situated in the south-west lowland wet zone of Sri Lanka and falling into the Sabaragamuwa and Southern provinces, Sinharaja is surrounded by Napola Dola,  Koskulana  Ganga  (north),  Maha  Dola,  Gin  Ganga  (south-west),  the  Kalukandawa  Ela, Kudawa Ganga (west), Beverley Tea Estate and Denuwa Kanda (east).

The  elevation  of  the  Sinharaja  reserve  ranges  from  200m  to  1300m.  It  has  a  rolling  terrain consisting  of  a  series  of  ridges  and  valleys,  which  assumes  an  east-west  trend  in  the northwestern part of the reserve. In other parts of the reserve, the ridges and valleys assume a north-west/south-east alignment. The peak of Hinipitigala is the tallest, rising up to about 1150m. Other important ridges in the reserve ranges between 550-800m in  height Namely Moulawella (760m), Koskulana (797m), Sinhagala(742m), Kohilearambe  (575m),  Dotalugala (769m), and Tibbottagala (904m).

Sinharaja forest cover receives between 3614-5006 mm of rain throughout the year and has a minimum rainfall of over 200 mm even during non-monsoon periods. The mean temperature is between 18-27 degrees Celsius with humidity of 75% - 90%. Only a faint sunshine reaches the ground layer of the forest which ranges from 5% - 15% of the total sun light.

Sinharaja has a wild profusion of flora. The canopy trees reach heights of up to 45m, with the next layer down topping 30m.  Nearly  all  the  sub  canopy  trees  found  here  are  rare  or endangered.  More  than  65%  of  the  217  types  of  trees  and  woody  climbers  endemic to Sri Lanka’s rainforest are found in Sinharaja.

Sinharaja rain forest is home to 186 bird species and out of the 33 endemic bird species, 31 have recorded from Sinharaja. Apart from Birds 3-4 Elephants, around 15 Sri Lankan Leopards also recorded from Sinharaja Rain Forest. The most common larger mammal is the endemic Purple-Faced Langur.  Reptiles include the endemic Green Pit Viper and Hump-Nosed Vipers, and there are a large variety of amphibians, especially tree frogs. Invertebrates include the endemic common birdwing butterfly and the inevitable leeches.
