Thailand has many surprises in its heart and one of such is Emerald Pool. Situated in the southern part of Krabi, this natural hot spring which turned the rocks below into hot tubs attracts many visitors throughout the year. Originating from the underground volcanic passage, people like to dip into this relaxing bathtub after a mountain hike or forest expedition. Normally, the temperature of water remains in between 35 to 40-degree Celsius and has lots of natural minerals and salts with healing properties.
