About Chae Son Hot Springs
Chae Son Hot Springs, Thailand is a sulfurous geothermal spring area in Chae Son National Park, Mueang Pan District, Lampang Province, approximately 75 kilometres northeast of Lampang city. The spring produces water from nine boreholes at temperatures ranging from 73 to 82 degrees Celsius, forming steaming pools across a rocky, forested setting. The morning steam rising over the pools in cooler months is one of the park's most photographed scenes.
Visitors can use the open outdoor pools, soak in private mineral bath bungalows that pipe in diluted spring water, and boil eggs directly in the hot pools - a popular activity unique to the site. Egg-boiling takes approximately 10 to 15 minutes and produces a distinctive texture similar to an onsen egg, with a soft yolk and gelled white. A six-tiered waterfall accessible via a one-hour trail is nearby. The park has a visitor centre, campsite, bungalow accommodation, a restaurant, and food stalls. Family hot springs near Lampang with both open-air and private soaking options in a national park setting are uncommon in northern Thailand.

Suitability & Accessibility
Who Should Visit Chae Son Hot Springs
Chae Son Hot Springs suits families, nature travellers, and visitors who want a genuine outdoor hot spring experience within a protected national park setting rather than a commercial spa facility. The combination of open steaming pools, private bath bungalows, and the surrounding forest make it appropriate for a wide range of visitors.
The private mineral bath bungalows are the most comfortable soaking option and are particularly suited to those who prefer privacy, families with younger children, or visitors less comfortable with communal open pools. The open pools are shallow and are used for the famous egg-boiling activity rather than full-body soaking; the water is too hot for extended immersion at the source. A swimsuit is recommended for the private baths. Insect repellent and sun protection are practical for the park grounds.
The waterfall trail, approximately one hour return, is accessible to reasonably fit visitors and does not require technical hiking experience. The terrain is forested and involves some uneven ground; it is not suitable for elderly visitors or those with significant mobility limitations. The area is at moderate elevation and cooler than lowland Thailand, particularly from November to February when the morning steam from the hot springs is most dramatic. Hot springs near Lampang in a national park setting like Chae Son attract both domestic Thai visitors and international tourists throughout the year.
Safety & Etiquette
Chae Son Hot Springs Safety Tips
Chae Son Hot Springs is generally safe when basic precautions are followed, but the water temperature at the pools is hot enough to cause scalding burns if touched at the source vents. The pools vary in temperature; always test the water carefully before entering or placing any body part into the water. Do not touch the boiling source vents directly. Children must be supervised closely at all times near the open pools.
The rocks around the hot spring pools can be extremely slippery due to mineral deposits and constant moisture. Walk carefully, use designated paths, and wear footwear with grip when moving between pools. The steam from the pools reduces visibility at close range, particularly in cooler early morning hours; be aware of the ground in front of you.
The private mineral bath bungalows supply diluted spring water at a more manageable temperature, but the water is still warm to hot. Allow the water to cool if needed before soaking. Monitor your body's response; limit continuous soaking to 15 to 20 minutes and stay hydrated. Pregnant visitors and those with heart conditions or skin conditions should exercise caution with high-temperature spring water.
Insects are active throughout the park, particularly in the rainy season from May to November. Bring mosquito repellent. The access road to the park is a mountain road; drive carefully, particularly in wet conditions. There is no mobile signal in much of the park. The park's nearest emergency services are in Lampang city, approximately 75 kilometres away; carry a basic first aid kit and inform someone of your plans before entering the park.
