Doi Inthanon National Park also known as “The Roof of Thailand”

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.
