Emerald Pool (Sa Morakot) is a stunning natural wonder hidden within the Khao Phra Bang Khram Nature Reserve in Krabi's tropical rainforest. The pool gets its distinctive emerald-green color from minerals in the water and reflection of surrounding vegetation. The cool-refreshing water temperature is perfect for swimming in the tropical climate. Nearby is the enchanting Blue Pool with its deep turquoise color, though swimming is prohibited there. A boardwalk trail connects both pools through the lush jungle.
