Bua Tong Fields

Bua Tong Fields at Doi Mae U Kho in Khun Yuam District, Mae Hong Son, is a vast seasonal mountainside covered with wild Mexican sunflowers (Tithonia diversifolia). Located within the Namtok Mae Surin National Park area, the fields bloom bright yellow across hillsides each cool season, creating a panoramic natural attraction. It is one of Thailand's largest and most photographed Bua Tong sites, known for its elevated viewpoints and annual flowering festival.

Visitors can expect wide rolling hills completely covered in bright yellow Mexican sunflowers during bloom season, with elevated viewpoints, walking paths and photo spots overlooking the valley. The site is an open mountainside landscape at about 1,600 meters elevation with cool air, surrounding forested hills, and simple visitor areas including viewpoints, trails and stalls. The experience is primarily sightseeing and photography of the seasonal floral landscape.

Bua Tong (Mexican sunflower) bloom is a celebrated seasonal event in Mae Hong Son, with the annual Khun Yuam Bua Tong Blossom Festival featuring local cultural performances, markets and community gatherings that highlight the natural heritage of the highlands.
