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.Visiting Doi Inthanon is possible throughout the year however, the best period for viewing the waterfalls is May through November while the best period for viewing wild flowers is December through February and for ornithologists is November through March.
Getting there: Travel 58 kilometres west of Chiang Mai via Highway No. 108 to Chom Thong, then turn right into Highway No. 1009 and continue a further distance of 48 kilometres along Highway No. 1009 to the summit. A good asphalt road takes visitors up but is rather steep, thus the vehicle must be in a good condition. Visitors could pay for the entrance fee at Km. 8.
Doi Inthanon can be reached by a local truck (Song Thaeo) from Phra That Chom Thong or Mae Klang Waterfall. The Song Thaeo runs to Doi Inthanon National Park Office (Km. 31) and neighbouring villages. A chartered Song Thaeo costing around 800 baht can make stops at other attractions around the area.
Admission : adult 400 baht, child 200 baht
