Horton Plains National Park is a protected area in the central highlands of Sri Lanka and is covered by montane grassland and cloud forest. This plateau at an altitude of 2,100–2,300 metres (6,900–7,500 ft) is rich in biodiversity and many species found here are endemic to the region. This region was designated a national park in 1988. It is also a popular tourist destination. Mist can persist in the most of the day during the wet season. Many pools and waterfalls can be seen in the park, and Horton Plains is considered the most important watershed in Sri Lanka.
