Chae Son National Park possesses a historical background deeply intertwined with the way of life of the Mueang Pan people since ancient times. This area has long been revered as a sacred site and a precious resource that sustains communities around the Western Phi Pan Nam Range. Originally, locals referred to the area based on the physical appearance of hot springs emerging from rock formations. It was eventually established as Thailand’s 58th National Park in 1988 to preserve the vital watershed forests and rare geological phenomenaa natural legacy passed down through many generations.

The heart of the park is the Chae Son Hot Springs, consisting of nine boreholes formed by geothermal pressure with temperatures ranging from 73-82°C. In the past, this area served as a resting spot for hunters and foragers who utilized the steam to survive the biting cold. Today, it has been developed into a modern wellness destination while maintaining the pristine beauty of its rocky hot spring landscape. Boiling eggs in the mineral-rich water is a symbolic activity reflecting the traditional utilization of geothermal energy that has been inherited over time.

In terms of local legends and history, Chae Son is connected to the belief in Chao Pho Mueang Pan, the heroic guardian of this territory. The name Mueang Pan originates from the discovery of Pan (ancient iron tools) in the nearby area. The faith in the spirits guarding the forests and waters has kept the area surrounding the 6-tiered Chae Son Waterfall exceptionally lush. This waterfall flows down to converge with the hot mineral streams, creating a two-temperature waterway that has been a strategic resource for local consumption since ancient times.

Beyond its fascinating geological history, the Chae Son forest reveals its natural historical beauty during winter (January–February) through the blooming of White Orchid Trees (Dok Siew flower). These indigenous flowers have coexisted with the Mueang Pan forest for centuries, serving as temporal witnesses to the seasonal changes in the Lanna region. The park provides welfare accommodations and camping zones, allowing visitors to experience the serene atmosphere that was once a site for ancient communities and transit routes.

A visit to Chae Son National Park is more than just a relaxing mineral soak; it is a journey to experience the Breath of the Earth, where the intense heat of the springs and the icy chill of the waterfall harmonize perfectly. It is a natural heritage that tells the story of the sustainable coexistence between humans and the forest in Lampang.
