Sra Morakot, whose name means Emerald Pool, is a beautiful natural pool hidden deep in the rainforest of Krabi, Thailand. This almost round pool is about 1-2 meters deep and 20-25 meters in diameter. The water of the Sra Morakot pool in Krabi comes from layers of porous rocks. It flows through cracks in the rocks to cascade down to the pool.
I visited Sra Morakot with a big busload of AsiaExplorers members, when we were places in South Thailand. It was a wet evening when we arrived there, and I had to take my tripod into the stream to get the motion shots of the running water. It was wet but fun!

Even though the water of Sra Morakot is crystal clear, it is not suitable for drinking due to its high calcium carbonate content which can cause gallstone. The calcium carbonate (CaCO2) from the spring water of Sra Morakot is deposited more on the edges of the pool than in the bottom. This is because the carbon dioxide (CO2) from the carbonic acid solution (H2CO3) in the spring water vaporizes better along the edges of the pool than in the bottom. Along the slopes leading down to the pool where there is water seepage from the ground, calcium carbonate is also deposited, producing a soft, slippery form.
Bacteria and algae in the water, along with the water temperature, determines the colour of the water of Sra Morakot. Where the water temperature is high, the water is greenish blue; where the temperature is lower, it is pale green. Visitors are advised not to use detergent, shampoos and soap when bathing in Sra Morakot, as these substances may affect the algae and the colour of the water of Sra Morakot.
