THAM HEUP CAVE Tham Heup is a large and impressive cave that you can walk right through. The cave is 1,1 kilometers-long, and has some beautiful rock formations, a pond, and a beach. The entrance is 20 meters-wide and 15 meters-high, with a interior that varies from 10 - 30 meters-high.
How to get there: The cave can be accessed from Ban Nakhok village by crossing the Hinboun River and walking for 1,5 kilometers. In the wet season the cave can be reached by boat along a branch of the Hinboun River near Ban Nakhok. About 3-4 kilometers south-east of the cave is a beautiful sacred forest with an abandoned temple. Also in the area is a small Buddha cave called Tham Jong. A local guide is required for these visits and can be arranged in Ban Nakhok.
