Tham Kong Lo is the name for the Kong Lo Cave which is part of the wider Phu Hin Bun National Park.
The park and cave sit along the Phu Hin Bun River and the central chamber is said to be one of the most spectacular in all of Southeast Asia.
The cave is some 6.5 kilometers long and is 300 feet high and is known for its stunning jade-hued pools which are said to be the same color as the skin of the Hindu god Indra.
The best way to check out the cave is to take a boat trip along the amazing chamber and enjoy the rock crystals and stalagmites and stalactites here.
