The Phraya Nakhon Cave is located inside Khao Sam Roi Yot National Park. Phraya Nakhon is a large cave which has a hole in the ceiling allowing sunlight to penetrate. At the top of the hole, there is a stone bridge known as "death bridge" because many wild animals have fallen to their deaths from it.
There is a water well at the foot of the mountain known as Phraya Nakhon Well. It is made of baked clay bricks in a trapezoidal shape. Visitors can go to the cave by renting a boat or by walking across Tian Mountain. After that, there is a climb up the mountain about 430 meters (1,410 ft) to reach Phraya Nakhon Cave. Its most famous early visitor was King Chulalongkorn.
