Thailand's highest peak, Doi Inthanon, rises to a height of 2,565 meters. Doi Luang, which translates to "Big Mountain" in Thai, was the mountain's prior name. The Mae Ya waterfall, for example, is located in the lower and mid-elevations of the mountain. The mountain's top reaches are covered in a dense canopy of montane forests, which are dominated by oaks, tea trees, and magnolia trees. Plants including orchids, lichens, mosses, and ferns thrive in the deep canopy. Deciduous woods can be found at lower elevations.

The Doi Inthanon National Park encompasses the entire mountain and neighboring territories, as well as their flora and fauna. Over 400 bird species call the mountain home, including rare species found only in a few of Thailand's mountains. The green-tailed sunbird and the ashy-throated warbler are two examples of such birds. The mountain is home to gorals, bears, and deer, as well as snakes and other tiny animals.

The mountain is the source of the Ping River and its tributaries. Because the mountain's slopes are particularly fruitful, the local communities have used them for agricultural purposes. In the 1970s, the military constructed a tarmacked road on the mountain, making tourism activities easier and more accessible.
