Thepphanom Hot Spring is a natural hot spring attraction located in a protected forest area of Mae Chaem District, Chiang Mai, in the Om Kut area, Kong Khaek Subdistrict. The charm here isn’t “commercial-scale” grandeur, but a wide-open forest setting where hot spring pools are scattered around the site, with a larger central pool acting like the heart of the area. Visiting feels like a slow nature walk where you can actually sense the earth’s geothermal energy still at work.

 

Overall, Thepphanom Hot Spring has more than 15 pools, including hot spring pools and seepage pools. These pools align in a north–south direction along a fault line, and the water merges into a warm stream that flows into the Mae Chaem River. A key feature is that each pool has a different temperature (local information often mentions roughly 30–90°C). The best way to enjoy the place is to “choose your timing and spots” — walk past the steaming pools first, then find a comfortably warm area to rest and relax.

 

Geologically, the surrounding area contains various rock types, such as rounded boulders rich in quartz, along with metamorphic rocks like biotite gneiss, schist, phyllite, and slate. These rocks are often described as Silurian–Devonian in age. When this geology is paired with local fault structures, it helps explain why groundwater can rise to the surface in multiple pools and form the warm stream you see today.

 

Another thing most visitors notice immediately is the smell. Many gas bubbles rise with the hot spring water, and the sulfur scent is quite distinct. Mineral alteration products such as silica, iron, and carbonate are also found, which is why some areas may show natural deposits or coloration that looks different from ordinary water. These are normal characteristics of natural hot spring systems, and they’re part of what gives this place its unique identity.

 

The walking area around Thepphanom Hot Spring is not very large. Local descriptions often mention a looped walkway of about 400 meters, with relatively flat ground, making it easier to stroll than many forest attractions. A favorite highlight is the large central pool, where the water can appear in a striking emerald-green tone. If you want to boil eggs, it’s recommended to bring eggs and your own basic equipment, as there may not be vendors on site at certain times (though services may appear during peak travel seasons).

 

As for the best season to visit, if you want the classic “soak in warm water and feel your body unwind,” winter is perfect. Late rainy season into early winter is also great, with lush green forest scenery, pleasant air, and comfortable walking conditions. The rainy season can be beautiful in terms of freshness and humidity, but extra caution is needed due to slippery paths and changing weather. If heavy rain is approaching, it’s safer to avoid stream areas and head back before dark.

 

Getting There If you start from Chiang Mai city, you can take Highway 108 (Chiang Mai–Hot) toward the Op Luang area, then turn onto the route to Mae Chaem District. Continue to Kong Khaek Subdistrict and the Om Kut area to reach Thepphanom Hot Spring. The road is mountainous with curves and some narrow sections, so drive at a steady pace, keep safe braking distance, and avoid traveling at night for safety.

 

 

A: Local information notes that there are more than 15 pools, including hot spring pools and seepage pools, and the temperature varies from pool to pool.

 

A: The sulfur smell is fairly noticeable because many gas bubbles rise with the hot spring water. If you’re sensitive to odors, consider bringing a mask and resting in well-ventilated areas.

 

A: Winter and late rainy season into early winter are usually the most comfortable, with good weather and pleasant walking conditions. The rainy season can be beautiful but requires extra caution due to slippery paths and changing weather.

 

A: Non-slip footwear, a towel and a change of clothes, drinking water, and a bag for your own trash. If you want to boil eggs, it’s best to bring eggs and basic equipment yourself.

 

A: Yes. The walking distance is relatively short and fairly flat, but children should be closely supervised near hot pools. Watch for slippery surfaces and avoid pools that are very hot or marked with warning signs.
