Doi Inthanon National Park is a national park in Chiang Mai Province of Northern Thailand. This is a place well worth a visit when you are in Chiang Mai. It is easily done in a day trip. It is about 115 km from Chiang Mai.
Doi In is the highest mountain in Thailand, at 2,599 m (8,527 ft), just a little higher than Australia's highest (Mt Koszciusko) which is 7,310 ft (2,228 m), and although it is relatively cold up at the summit, it never snows.
Doi Inthanon is a part of the Himalayas, which ranges across Nepal, Bhutan, Myanmar, and ends in northern Thailand. Complex mountain ranges and a mild climate characterise the area with a moist and dense summit forest. Doi Inthanon is interesting for ornithologists. The summit forest is the source of important tributaries of the Mae Ping River. Meo and Karen hill tribes inhabit the park.
