The station was established in 1969 as the first research center under the Royal Project Foundation.
The area experiences frost during the coldest months of the year, a rarity in Thailand.
The mountain hosts rare migratory bird species during the winter season.
The Royal Project successfully replaced traditional shifting cultivation and opium production with high-value temperate crops.
The elevation creates a microclimate allowing for the cultivation of Japanese plums and various varieties of tulips.
Doi Ang Khang is a high-altitude mountain region in Fang District known for the Ang Khang Royal Agricultural Station, which was established by King Rama IX to replace opium poppy cultivation with temperate fruit and flower farming. The peak reaches elevations of approximately 1,400 meters, resulting in a significantly cooler climate than the lowlands of Chiang Mai. The station functions as a research facility for temperate crops such as peaches, plums, strawberries, and various ornamental flowers. Several distinct garden zones, including a bonsai garden and a rose garden, are integrated into the facility. The area serves as a habitat for diverse bird species, making it a recognized site for birdwatching. Visitors can observe the transformation of local agricultural practices through the experimental orchards and greenhouses. The mountain ridge marks the border between Thailand and Myanmar. The site is part of the Royal Project Foundation, a non-profit organization promoting sustainable highland development.

Bring a warm jacket as temperatures drop significantly at night, even during the summer.
Use lower gears when driving, as the access roads are exceptionally steep with tight switchbacks.
Visit during the early morning to avoid the densest fog that often settles over the mountain.
Attempting to visit during the New Year holiday period, as local traffic congestion can lead to multi-hour delays on the mountain access roads.
The research station and gardens are open year-round, though peak blooming cycles for specific flower gardens occur primarily in the winter months.
Dress conservatively when entering agricultural zones; do not touch or pick crops and flowers in the research plots.
