The park's hot springs are used by locals to soft-boil eggs, which typically takes around 15 minutes in the dedicated mineral water pools.
The landscape is primarily composed of metamorphic and igneous rock, providing the geological conditions necessary for thermal spring activity.
The Chae Son Waterfall remains active year-round due to the stable forest cover protecting the upper watershed.
The park is home to the Doi Lan viewpoint, which provides a panoramic look over the surrounding Lampang and Chiang Mai topography.
Specific high-altitude areas within the park experience significantly cooler temperatures than the surrounding lowlands, even in the hot season.
Chae Son National Park is defined by its natural hot springs, which reach temperatures between 70 and 80 degrees Celsius. The park features a cluster of mineral-rich springs located in a misty, forested valley. Beyond the springs, the area hosts the six-tiered Chae Son Waterfall, fed by a perennial stream originating in the surrounding mountains. The geological activity creates a unique landscape of steam vents and sulfurous pools. Visitors can hike several forest trails that traverse the park's diverse terrain and mountain viewpoints. Bathing facilities, including private mineral-water rooms and a large public pool, are maintained on-site. The park spans approximately 768 square kilometers across the Khun Tan mountain range. It serves as a watershed area for the Lampang province and supports diverse wildlife populations including barking deer and various bird species.

Bring a towel and swimwear if you intend to use the public thermal pools or rent a private soaking room.
Carry a small basket of eggs to boil in the designated hot spring zone for a traditional local snack.
Wear sturdy, closed-toe walking shoes if you plan to hike the multi-level waterfall trail, as the rocks can be slippery.
Pack insect repellent, as the humid, forested environment near the waterfall attracts mosquitoes.
Do not attempt to touch or bathe in the primary hot spring source pools, as the water temperature is dangerous for humans.
Maintain a quiet volume in the bathing areas; wear modest swimwear when using public pools; do not leave trash in the forest areas.
