Ban Samo Thong Hot Spring, located in Uthai Thani Province, is a distinctive natural and wellness tourism destination. Established in 1997 under the Huai Khun Kaeo Reservoir Project, the area around the hot spring was developed into a small landscaped garden situated in the middle of the reservoir. The hot spring itself is naturally occurring, emerging from the ground and flowing through two mountain channels. What makes Ban Samo Thong Hot Spring unique is that it is the only hot spring in Thailand completely surrounded by water and adjacent to the Huai Kha Khaeng Wildlife Sanctuary, allowing visitors to experience nature up close.

 

The spring water is clear, has a strong sulfuric odor, and reaches temperatures of up to 68°C (154°F), enough to boil eggs in just five minutes. The water flows down the mountain rocks into the Kok Khwai Stream. The site has been developed to allow for health-promoting activities, including soaking in the hot spring, Thai massage, and enjoying scenic views, particularly at sunset.

 

Historically, Ban Samo Thong Hot Spring has been recognized by the royal family. On September 16, 2009, Her Royal Highness Princess Maha Chakri Sirindhorn visited the site, marking its cultural and tourism significance.

 

From a geological perspective, data from the Department of Mineral Resources in 2007 indicate that the hot spring is located on Triassic granite formations with fractures connected to two fault lines: the northeast-southwest and northeast-east-southeast directions. Gneiss, a metamorphic rock derived from granite, is also found in the area, interspersed with quartz minerals. Geothermal activity heats the spring water to temperatures of approximately 50°C (122°F). Originally, the area was covered with bamboo forest, and the water was even hotter. The construction of the reservoir and changes in the terrain cooled the surface water, making the temperature suitable for bathing and health treatments.

 

The physical environment at Ban Samo Thong Hot Spring is well-maintained, clean, and orderly, with adequate restrooms, clear signage, and accessible paths for people with disabilities.

 

The hot spring is primarily utilized for wellness tourism. Visitors can soak their feet or entire bodies in the mineral-rich water, often combined with traditional Thai massage to enhance relaxation and health benefits. The surrounding area also offers scenic viewpoints and beautiful spots for watching the sunset.

 

The site’s development is managed under the Huai Khun Kaeo Reservoir Project, which includes landscaped gardens, visitor reception buildings, soaking pools, foot baths, and solar energy installations. The area has been landscaped to serve as a comprehensive viewpoint with facilities for tourists.

 

Facilities at the hot spring include visitor reception buildings, accommodation rooms, meeting rooms, soaking pools, foot baths, restrooms for the general public and people with disabilities, parking lots, water treatment systems, shops, and electrical control rooms. The design carefully balances aesthetic views of the reservoir with visitor convenience, making Ban Samo Thong Hot Spring a key attraction in Uthai Thani Province that harmonizes nature, wellness, and comfort.

 

Ban Samo Thong Hot Spring exemplifies sustainable wellness tourism, emphasizing environmental conservation, geological significance, and natural resource preservation. It attracts both domestic and international visitors seeking a unique experience that combines Thailand’s natural beauty with local cultural heritage.
