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.

The area around Yala has hosted several ancient civilisations. Two important pilgrim sites, Sithulpahuwa and Magul Vihara, are situated within the park. The 2004 Indian Ocean tsunami caused severe damage on the Yala National Park and 250 people died in its vicinity. The number of visitors has been on the rise since 2009 after the security situation in the park improved.
