Mokhin Khao is a remarkable geological formation consisting of three major groups of stones. The first group features five large, white sandstone pillars resembling towering columns, arranged in a curious row atop a hill. Each pillar stands approximately 12 meters tall, giving rise to the name "Mokhin Khao." Beyond this, there are stone formations that take on the shapes of a boat, a pagoda, the Leaning Tower of Pisa, and even a turtle shell. The second group of stones is located 500 meters away and is characterized by platforms of uniquely shaped rocks. Further still, about 1,500 meters from the second group, lies the third group, which consists of smaller stone platforms and pillars, sloping upwards towards a cliff known as Pha Hu Nak.
