Horton Plains National Park, a UNESCO World Heritage Site, is a unique montane plateau at an elevation of over 2,000 meters.
The park features montane cloud forests with unique high-altitude vegetation. Notable species include Calophyllum walkeri (Keena), dwarf bamboo, and tree ferns. The plains are dotted with rare orchids and rhododendrons (Rhododendron arboreum). Many tree species are endemic to these high elevations.
The park is home to endemic mammals like the Sri Lankan sambar deer and purple-faced langur. Notable bird species include the Sri Lanka whistling thrush and Sri Lanka bush warbler. The park also supports numerous endemic amphibians and reptiles adapted to the cold climate.
