About Hin Dat Hot Spring (Kuimang Hot Spring)
Natural open-air thermal pools set right beside a cool mountain stream, so you can go back and forth between the hot spring and the cold water. It was discovered by Japanese soldiers in WWII, and it's a cheap, low-key spot the locals love. The hot-cold contrast is at its best after the rains, when the stream runs coolest.
Set your expectations to rustic. This is not a manicured resort spa, it's a communal, no-frills soak. That's part of its charm if you're in the right frame of mind.
It sits on the long road toward Thong Pha Phum and Sangkhla Buri, about 130 km from Kanchanaburi town, too far out for a standalone day trip from town. Fold it into an overnight Kanchanaburi or Thong Pha Phum trip, or use it as a leg-stretch on a longer drive. Come early morning or evening for the nicest soak, and expect more people on weekends.
