About Hin Dad Hot Spring
Hin Dad Hot Spring, Thailand is a natural calcium-carbonate hot spring on the riverbank in Thong Pha Phum District, Kanchanaburi Province, located on Highway 323 approximately 130 kilometres from Kanchanaburi town. The spring was discovered in 1943 by Japanese soldiers overseeing construction of the Death Railway during World War II. It was previously known as Kui Mang Spring before taking its current name.
The site features three concrete pools of varying temperatures ranging from approximately 40 to 50 degrees Celsius, each suited to different preferences. The hottest and deepest pool is best for a full-body soak; the shallower pools allow foot-soaking or gradual temperature adjustment. The pools are positioned directly beside a river, allowing visitors to cool down in the flowing water between soaking sessions. The site also has a dedicated pool for visitors with disabilities. Accessible hot springs near Kanchanaburi of this historical significance and riverside character are rare in the region. The spring water is odourless due to its calcium-carbonate composition, distinguishing it from sulfurous springs found elsewhere in Thailand.

Safety & Etiquette
Hin Dad Hot Spring Safety Tips
Hin Dad Hot Spring is generally safe for healthy adults and children when basic hot spring precautions are observed. The pools reach up to 50 degrees Celsius, which is hot enough to cause discomfort if you stay in too long or submerge suddenly without adjustment. Enter the water gradually, starting from the feet, and allow your body to acclimatise before a full immersion. Begin with the cooler pools if visiting for the first time.
The rocks and pool edges around the spring area can be slippery when wet. Walk carefully and wear footwear with grip when moving between pools. Take extra care entering and exiting the pools. Children must be supervised at all times near the pools and near the adjacent river. The river current can be strong depending on season and recent rainfall; do not allow young children in the river unsupervised, and be cautious yourself at any time the river is running fast.
Limit continuous soaking in the hottest pool to 15 to 20 minutes. Alternate with cooler pools or cool-down breaks in the river if comfortable and safe to do so. Stay well hydrated throughout the visit; the heat can cause dehydration faster than expected. Pregnant visitors and those with cardiovascular conditions, diabetes, or other chronic health conditions should seek medical advice before using hot spring facilities.
The hot spring water is odourless and calcium-carbonate in composition, making it gentler on skin than sulfurous springs. Even so, visitors with sensitive skin should monitor their reaction to extended soaking. The site's on-site facilities include showers for rinsing off after soaking. Do not drink the spring water. The nearest medical facilities are in Thong Pha Phum town, approximately 30 kilometres to the south.
