Doi Inthanon Guide: Highest Mountain In Thailand

The awe inspiring views you’ll enjoy from the mist-shrouded peak of a Doi Inthanon tour makes it easy to understand why this mountain has been nicknamed ‘The Roof of Thailand’.

Known in the past as Doi Luang (big mountain), magnificent Doi Inthanon now takes its name from the former King Inthawichayanon of Chiang Mai, who made it his mission to preserve the mountain and its surrounding forests.

It’s the highest mountain in Thailand, and it’s a must see for visitors.

The Highest Mountain in Thailand

Situated in Chiang Mai province in the north of Thailand, Doi Inthanon is at the heart of its own immense national park which sprawls over 482 square kilometers of tropical forest covering many climatic and ecological zones.

The mountain itself is part of the Thanon Thong Chai mountain range which varies between 800 meters above sea level at its lowest point with the peak of Doi Inthanon being its crowning glory at the highest point of 2565 meters above sea level. It is also considered part of the foothills of the Himalayas.

Owing to its large height, the climate on the mountain is variable – and generally cooler than elsewhere in Thailand. Doi Inthanon National Park has high humidity and chilly weather all year round. At high altitude on the summit temperatures can drop as low as 32°F (0°C) in January, and during the rainy season (April to November) it often rains for more than 2 hours a day.

Flora and Fauna

Something of a national treasure, Doi Inthanon was declared a National Park in 1972 and formally extended in 1978 to include the surrounding lowlands. Other than the obvious allure of the mountain itself, there is an abundance of flora and fauna here to attract nature lovers — some of the widest variety in Thailand.

The park is a paradise for bird enthusiasts as it is home to the second largest number of species of birds (382 in total) in the country.

Doi Inthanon is of particular conservation importance for those species which inhabit the humid evergreen forests of the upper slopes. Two rare species that are uniquely seen on the mountain are the Ashy-throated Leaf-Warbler and a special variety of Green-tailed Sunbird. The best time to bird watch is during the breeding season which lasts from March until as late as July for some species.

Sadly due to hunting and habitat change many of the larger mammals have disappeared from the park, but it is nevertheless still home to around 75 mammal species. Rare animals like the Asiatic black bear, Assamese macaque, and Phayre’s leaf-monkey can still be seen here, as well as more common creatures such as barking deer, civets and giant flying squirrels. The flora consists of sphagnum bog, moist evergreen cloud forest, dry evergreen, pine, teak and dipterocarp forests.

Places of Interest

But the wildlife isn’t the only thing to experience here – the impressive waterfalls that cascade down Doi Inthanon’s slopes are not to be missed. Perhaps the most impressive are multi-tiered Mae Ya waterfall which plunges over 250 meters, and the fast flowing Wachirathan waterfall whose powerful torrents drench you in spray.

Another natural wonder to enjoy on Doi Inthanon is Tham Bori Chinda cave. An hour’s trek from the main road, this large cave has been naturally formed from the limestone mass of the mountain. Sunlight enters inside the cave and reflects off the surface off the water to reveal some remarkable stalactite and stalagmite formations, plus carved Buddha images.

Also worth a visit are the two chedis (stupas) constructed in celebration of the 60th birthdays of the late King and Queen of Thailand (in 1987 and 1992 respectively). The twin chedis are set in superb and immaculately landscaped gardens among the clouds, and a visit here is a serene experience.

Another sight worth seeing is the Doi Inthanon Royal Project in Khun Klang village. This project was founded by the royals back in the 70s to help educate the hill tribe population in new agricultural practices, in order to persuade them away from the opium harvest.

The project is home to some truly beautiful plantations and an interesting plant breeding research centre.
