Topography and climate
Historically, the mountain of Doi Inthanon was refered to as Doi Ang Kha. Prince Intharawichayanon, the last ruler of Chiang Mai, realized the importance of the country's forests especially those in the north where they serve as the sources of headwaters for much of the country. He helped support people to study the areas. He requested that his remains be placed on the summit of Doi Ang Kha. After his death, the mountain was renamed Inthanon, a shorten version of his name. Today, visitors to the summit can see the remains of the prince there.

The Park is ruggedly mountainous. Doi Intanon, the highest peak stands at 2,565 meters above sea level. Lesser peaks include Doi Hua Luang (2,330 meters). The park is the source of headwaters for the Mae Klang, Mae Pako, Mae Pawn, Mae Ya, Mae Cham and Mae Khan rivers. The water from the park helps generate electricity at the Bhumipol dam site in Tak province.

Because of the park's high altitude, the climate is cool all year round. January is the coldest month with an average temperature of 5.5ºC. Even in the hot season (March to June) the temperature remains pleasant, particularly at higher elevations. Rain, fog and mist can obscure the view for days.

The forest of the park is one of the country's most important heritages. Forest types include moist evergreen forest, pine forest and mixed decidousus species with economic value including teak, mountain pine, etc. In addition there are many beautiful flowers including vanda, phycastylis and rhododendron. Mosses such as sphagnum and osmanda are found at higher elevations. There are Royal Projects, assisting the villagers grow cold-climate fruit such as strawberries, grapes and apples as well as flowers in the park. The number of wild animals in the park is decreasing due to hunting, farming and tourism activities, etc. The remaining animals include serow, gibbons, very few tigers, deer, wild pigs, Siamese hare, jungle fowl and goral.

Because of its wide altitude range and the cool climate in its upper reaches, the park supports the largest number of bird species in Thailand. The Center for Wildlife Research at Mahidol University recorded a total of 362 species. In addition, there are many migrants from northern Asia seen at summit areas. Species restricted to Doi Inthanon are Ashy-throated Warbler and an endemic race of the green-tailed Sunbird.
