Doi Inthanon National Park

This national park which covers an area of 1,005 square kilometers is located on Doi Inthanon, Thailand’s highest mountain which is 2,565 meters above sea level. Located between Mae Chaem and Chom Thong, the park is comprised of the largest tract of upper mountain forest which ranges across Nepal, Bhutan, Myanmar, and ends in Northern Thailand. The mountain ranges gave birth to the main tributaries of the Ping river and formed the beautiful waterfalls, namely Siriphum, Wachirathan, Mae Pan, Mae Klang and Mae Ya. The moist and dense evergreen forest is abundant with lichens and wild orchids. The park is also a paradise for bird lovers.
