The Horton Plains National Park at Ohiya is a beautiful highland plateau situated at an elevation of 2100 -2300m (6,900-7,500ft) above sea level. Sri Lankaâ€™s Highlands along with Horton Plains National Park, the Peak Wilderness Protected Area and the Knuckles Conservation Forest was declared a World Heritage site in 2006.It is accessible via Ginigathena (185.4 km) or via the A5 Road (228.5 km) which connects Peradeniya with Chenkalady in the east via Gampola & Nuuwara Eliya.
Horton plains has an interesting history behind it with the discovery of early stone tools dating back to the Balangoda Culture (According to Archeological sequences the earliest evidence of Balangoda Man at caves and other sites dates back to 38,000 BP).
The weather at the plains varies considerably during the course of the day with temperatures as high as 27 degrees centigrade during the day and dipping as low as 5 degrees centigrade in the evenings and night with thick mist formation and regular rainfall throughout the year.
This protected area situated in the southern plateau of the central highlands of Sri Lanka was formerly called â€˜Maha-Eliya Tennaâ€™ (The great open plains) until it was renamed â€˜Horton Plainsâ€™ after the British Governor of Ceylon Sir Robert Wilmot Horton (1831-1837). It is rich in biodiversity with many species endemic to the area itself. Horton Plains was designated a National Park in 1988 and is today a very important and popular tourist destination.
The Horton Plains vegetation is classified into two distinctive groups, mostly consisting of montane grasslands and lesser sub tropical montane evergreen cloud forests. It is also where two important peaks Kirigalpoththa and Thotupolakanda, the second and third highest peaks in the country respectively are situated, making it a key catchment area of three major rivers in the country. Close to 750 species of plants have been observed here; this includes dwarf bamboo species (some endemic to Sri Lanka), Myrtaceae and Lauraceae species, and many varieties of ferns, lichens and orchids amongst others. The fauna of the region includes 24 species of mammals, 87 species of birds, 09 species of reptiles, 15 species of amphibians and 02 species of fish.
