The mountain was formerly known as Doi Luang or Doi Ang Ka, meaning 'crow's pond mountain'.
It was renamed Doi Inthanon in honor of King Inthawichayanon, the last ruler of Chiang Mai, whose remains are interred there.
The summit hosts a radar station operated by the Royal Thai Air Force.
It is home to the Kew Mae Pan Nature Trail, which features high-altitude rhododendrons that bloom in early spring.
The sphagnum bog at the summit is one of the highest in Thailand and remains permanently waterlogged.
The mountain's microclimate supports rare species like the Ashy-throated Warbler and the Green-tailed Sunbird.
There is a shrine at the summit containing the ashes of King Inthawichayanon as per his final request.
The park contains several waterfalls, such as Wachirathan, which is fed by the mountain's runoff.
Doi Inthanon stands as Thailand's highest peak at 2,565 meters above sea level within the Himalayan mountain range extension. It serves as the core of Doi Inthanon National Park, covering 482 square kilometers across the Chiang Mai province. The summit area features a cloud forest ecosystem characterized by high humidity and year-round cool temperatures. Visitors can access the peak via a paved road that winds through various forest types, including dry evergreen, pine, and sphagnum bog. The mountain acts as a watershed for the Mae Ping River, which eventually feeds the Chao Phraya River. Two prominent chedis, Phra Mahathat Naphamethanidon and Phra Mahathat Naphaphonphumisiri, are situated near the summit to honor the late King and Queen. The park contains significant biodiversity, including over 500 bird species and several endemic flora varieties. During the winter months, temperatures at the summit can reach freezing, leading to frost on vegetation.

Bring a warm jacket or fleece as temperatures at the summit are significantly lower than in Chiang Mai city.
Wear shoes with good grip, as boardwalks and trails can become slippery due to the constant mist.
Visit the secondary peaks or nature trails early in the day to minimize the chance of thick cloud cover obscuring the view.
Do not attempt to hike the summit trails during heavy monsoon rains when paths become hazardous; avoid visiting during weekends if seeking solitude.
The Kew Mae Pan Nature Trail is typically closed for ecosystem recovery during the monsoon months, usually from June to October.
Maintain a quiet demeanor near the royal chedis; dress modestly by covering shoulders and knees when visiting religious monuments.
