Doi Inthanon is the highest mountain in Thailand with the height of 2565 metres above sea level. It is part of the Himalayan Mountain System, which stretches all the way from Nepal, Bhutan and Myanmar to Northern Thailand. Doi Inthanon has different types of landscapes and forests including rainforest, coniferous forest, and mixed deciduous forest. In addition, due to its year-round cold climate, especially in cool season, it is usually foggy all day long on the peak and dew sometimes freezes. These continuously attract many visitors to Doi Inthanon.
