Pha Khong Cave offers a stunning experience with its abundance of stalactites and stalagmites within this important ecosystem of Doi Phu Kha National Park. The cave features numerous interconnected chambers, each filled with uniquely shaped and beautifully formed limestone formations that captivate visitors. However, during the rainy season, water flows into the cave, making it impossible to explore. It’s essential to prepare your own flashlight and other necessary equipment for the trip. Be sure to contact the park authorities in advance for any arrangements. You can reach them at 02-561-0777, extension 1723.
