Khlong Thom Hot Spring Waterfall is a natural hot spring with a temperature of approximately 40-50 degrees Celsius. This hot waterfall is caused by an underground hot mineral source that seeps up from the surface in a cascading pattern similar to a small waterfall. In some parts there is smoke and natural limestone deposits, creating unusually beautiful scenery. Only in the area where the level drops, it becomes similar to a small waterfall. There will be a small puddle of water. It’s like many bathtubs. We can swim or soak in the natural hot springs in Japan.
