Ban Khun Klang Community (Ban Khun Klang) is a large Hmong hill tribe village located at Kilometer 31 of Highway 1009 within Doi Inthanon National Park, Chom Thong District, Chiang Mai Province. Situated at an altitude of approximately 1,200–1,400 meters above sea level, it enjoys a pleasant cool climate all year round, with temperatures often dropping below 10 degrees Celsius during the winter. This makes the area ideal for cultivating cool-season crops, ornamental flowers, and temperate fruits, establishing it as one of Thailand's most important high-altitude agricultural areas.

In the past, the Ban Khun Klang community, like many other high-altitude villages in the North, practiced shifting cultivation and opium farming. It later underwent development under the Royal Project, initiated by His Majesty King Bhumibol Adulyadeadej The Great, through the establishment of the Inthanon Royal Agricultural Research Station to research cool-season crops, disseminate agricultural knowledge, and promote stable livelihoods for the community. This transformation made Ban Khun Klang a model for high-altitude community development alongside natural resource conservation.

The Inthanon Royal Agricultural Research Station is a hub for various cool-season plant species, including ornamental flowers, vegetables, fruits, and economic crops such as chrysanthemums, roses, lilies, azaleas, hydrangeas, strawberries, passion fruit, avocados, Arabica coffee, macadamia, as well as salad greens and cool-climate herbs. The station also features experimental greenhouses, demonstration plots, a learning center, shops selling fresh produce, and processed products from the Royal Project, where tourists can purchase seasonal produce directly from farmers.

A major highlight of Ban Khun Klang is the Glowing Chrysanthemum Gardens, which are highly popular during winter. Farmers use light bulbs over the flower beds at night for Photoperiod Control, an agricultural technique that helps delay flowering and ensures chrysanthemums bloom precisely when market demand is high, especially during important festivals. From a distance, thousands of lights illuminate the hillsides and valleys, creating a beautiful spectacle dubbed the "Valley of Light" or "Glowing Flower Garden of Doi Inthanon." Visitors can enjoy this sight from early evening until approximately 9:00 PM during November–February.

Winter is also a season of vibrant cool-climate flowers, especially the Wild Himalayan Cherry, or Thai Sakura, which blooms in pink across the Inthanon Royal Agricultural Research Station and along the roadsides from late December to early February. Additionally, there are fields of chrysanthemums, asters (cut flowers), gypsophila, and many other cool-season flowers that take turns blooming throughout the tourist season.

Another charm of Ban Khun Klang is the traditional Hmong way of life, which has been well preserved. Tourists will see typical high-altitude community houses, traditional attire during festivals, and a community market selling fresh vegetables, cool-season fruits, flowers, fruit wine, herbal tea, freshly roasted Arabica coffee, and local handicrafts that reflect indigenous wisdom.

Ban Khun Klang also serves as a central hub for tourism in Doi Inthanon, being close to several important attractions such as Siriphum Waterfall, Phra Maha That Naphamethinidon and Phra Maha That Naphaphonphumisiri, Kew Mae Pan Nature Trail, Vachirathan Waterfall, Doi Inthanon Summit, and Ang Ka Nature Trail. Many tourists prefer to stay overnight in Ban Khun Klang before heading out to witness the sunrise or sea of fog on the mountaintop in the early morning.

Within the village, comprehensive facilities are available, including restaurants, coffee shops, convenience stores, Royal Project product shops, a community market, homestays, resorts, and several camping grounds. This allows for convenient overnight stays, offering a chance to experience the cold weather and the high-altitude community's way of life up close.

Beyond its natural beauty, Ban Khun Klang stands as a successful example of high-altitude development based on royal initiatives, creating sustainable income for the community while preserving the headwater forests of Doi Inthanon National Park. It is therefore one of Chiang Mai Province's most valuable natural, agricultural, and cultural tourist destinations, and a must-visit for travelers to Doi Inthanon in all seasons, especially during winter when the atmosphere is at its most beautiful.
