Nam Tok Haew Narok

Top choice waterfall in Khao Yai National Park

Nam Tok Haew Narok ('Hell Gorge Waterfall') is in the far south of the park, 23km from the visitor centre. Its three levels combine to form a 150m drop, making it the park's biggest. It's pretty easy to walk the 800m paved path to the top of the 50m first level, but then it's a 199-step descent to the falls' viewpoint. The second and third levels aren't accessible.
