Erawan National Park is a 550 km2 park in western Thailand in the Tenasserim Hills of Kanchanaburi Province, Amphoe Si Sawat in tambon Tha Kradan. Founded on August 14, 1975, it was Thailand's 12th national park.
The major attraction of the park is Erawan Falls, a waterfall named after the erawan, the three-headed white elephant of Hindu mythology. The seven-tiered falls are said to resemble the erawan. There are four caves in the park: Mi, Rua, Wang Bahdan, and Phartat. Rising northeast of the waterfall area there is a breast-shaped hill named Khao Nom Nang.
