Erawan National Park is a 550-square-kilometer park in western Thailand located in the Tenasserim Hills, Kanchanaburi Province, Amphoe Si Sawat in the tambon Tha Kradan. Founded in 1975, it is 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. The Erawan Falls are contenders for the most beautiful waterfalls in Thailand. There are also four caves in the park: Mi, Rua, Wang Bahdan, and Phartat.
