Doi Inthanon National Park is Thailand’s highest mountain, 2,599 metres above sea level. Doi Inthanon is a part of the Himalayas, which ranges across Nepal, Bhutan, Myanmar, and ends at Northern Thailand. Complex mountain ranges and a mild climate characterise an area with a moist and dense summit forest. Doi Inthanon is very intersting for ornithologists. Summit forest is the source of important tributaries of the Mae Ping River. Meo and Karen hilltribes inhabit the park.
