The Emerald Pool
Also known as Sa Morakot to the locals, this is a naturally occurring pool which gets its name, not surprisingly, because of its colour. The Emerald Pool is located in the Khao Pra-Bang Khram Wildlife Sanctuary in the Klong Thom district of Krabi province, a distance of 70 kilometers from the center of Krabi town. A comfortable journey by road will get you there in about an hour or so.
Walk down the narrow tree-lined path for about ten minutes, as it meanders under the leafy canopy. The signs will eventually lead you to this clearing, with the gorgeous Emerald Pool peeking out.
The Emerald Pool’s pure spring water comes from the natural streams that originate in the hills above and run in to it. The colour comes from its chemical composition: a mixture of calcium carbonate, magnesium and minerals. It is quite a popular site with both tourists and locals alike, so try visiting early in the day to beat the rush. Swimming is permitted here, so the pool can get VERY crowded.
