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 Maenam Ping 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 kilometers west of Chiang Mai via Highway No. 107 to Chom Thong, then turn right into Highway No. 1009 and continue a further distance of 48 kilometers along Highway No. 1009 to the summit. A good but rather steep asphalt road takes visitors up, thus the vehicle must be in a good condition. Visitors could pay for the entrance fee at Km. 8.
