With a great height of 2565 meters, Doi Inthanon is known as the tallest mountain in Thailand. Primarily, Doi Inthanon was called Doi Luang referring to its gigantic peak and Doi Ang Ka or “crow pond peak” because there was once a pond frequently visited by crows on th peak of the mountain.
A new name of Doi Inthanon was given as a honor to King Inthawichayanon, whose name was locally called as King Inthanon. Before Lanna Kingdom was merged into Siam, King Inthawichayanon was the seventh ruler of Chiang Mai's last dynasty. He showed a great concern for forest before any green movement launched and that makes him an environmentalist of the early-day.
