This is a small spring that sprouts up to the surface. The hot water from underground converges to form a little stream that flows down to Than Khok Khwai or Huai Khun Kaeo. The water is clear and pungent with the aroma of sulphur. The water is so hot that it can boil an egg in 5 minutes. The Royla Irrigation Department has constructed Huai Khun Kaeo Reservoir, flooding the stream and the spring itself. However, and earth levee has been developed around the spring and some landscaping has been done to create a good rest area for visitors. The spring has an area of 4,000 square metres and consists of 3 springs. A mineral bath is available for tourists and nearby is a 20-metre-high Buddha image sitting high amidst the wonderful scenery of the area.
