Yala National Park is the most visited and second largest national park in Sri Lanka. Actually it consists of five blocks, two of which are now open to the public; and also adjoining parks. The blocks have individual names also, like Ruhuna National Park for the (best known) block 1 and Kumana National Park or 'Yala East' for the adjoining area. It is situated in the southeast region of the country, and lies in Southern Province and Uva Province. The park covers 979 square kilometres (378 sq mi) and is located about 300 kilometres (190 mi) from Colombo. Yala was designated as a wildlife sanctuary in 1900, and, along with Wilpattu it was one of the first two national parks in Sri Lanka, having been designated in 1938. The park is best known for its variety of wild animals. It is important for the conservation of Sri Lankan Elephants and aquatic birds. There are six national parks and three wildlife sanctuaries in the vicinity of Yala. The park is situated in the dry semi-arid climatic region and rain is received mainly during the northeast monsoon. Yala hosts a variety of ecosystems ranging from moist monsoon forests to freshwater and marine wetlands. It is one of the 70 Important Bird Areas (IBAs) in Sri Lanka. Yala harbours 215 bird species including six endemic species of Sri Lanka. The number of mammals that has been recorded from the park is 44, and it has one of the highest leopard densities in the world.
Around 20km southeast ofTissamaharama lies the entrance to Yala national park (properly known as Yala West or Ruhunu national park), bri Lankas most visited wildlife reserve. Yala covers an area of 1260 square kilometres, although four-fifths of this is designated a Strict Natural Reserve and closed to visitors. On the far side of the Strict Natural Reserve is Yala East national park, which is currently only accessible via Arugam Bay.There's no public transport to Yala West, and you're only allowed into the park in a vehicle, so you'll have to hire a jeep.
