Doi Inthanon National Park covers an area of 482 km² in Chiang Mai province north of Thailand. The park is part of the Himalayan mountain range, elevation ranges between 800 and 2565 meters with the highest peak at Doi Inthanon which is the highest mountain in Thailand. Due to the high altitude, the park has high humidity and cold weather all year round. The average daily temperatures are normally around 10-12 °C.
The peak was formerly known as Doi Luang (“big mountain”) and Doi Ang Ka (“crow’s pond top”). The peak got its current name after King Inthawichayanon, one of the last kings of Chiang Mai, expressed his wish that his remnants be put to rest within the park grounds (which was still called Doi Luang until then). The king is known to have shown special interest in preserving and managing the forests. Thus, the peak was renamed to honor his demise and his remains were buried under the summit stupa.
The high elevation of Doi Inthanon has blessed the land with a rich biodiversity in terms of both flora and fauna. Come December to February, you can see the only red rhododendron in Thailand around the summit area. The forests around the park are a combination of Mixed Deciduous, Moist Evergreen, and Pine Forest. Go further up and you will notice how the landscape changes from deciduous forests to a larger tropical evergreen. Flowers around the park include Vanda Orchids and Phycastylis. Although larger animals aren’t a common sight anymore, you can spot Asiatic Black bears, Chinese flying Squirrels, Macaques, Barking Deer, Gibbons, and Leaf Monkeys and various (reportedly, around 30 different kinds) species of bats. Doi Inthanon, with a recorded total of 362 species of birds (and increasing), is one of the best treats to bird watchers. March to May is when the big migration happens with some birds mating even until June. Ask the tourist center for detailed bird list.
Visiting Inthanon National park is possible throughout the year. The best period for viewing waterfalls is May-Nov. The best period for viewing wild flowers is Dec-Feb. The best period for ornithologists is Nov-Mar.
