Technically, Heo Narok Waterfall is composed of 2-tiered falls; the 1st one is 50 meters high while the second level is higher than the first one. There are also another path to visit the national park in another cliff to experience the view of the second and third tiered. However, this trail is not open to public due to its entrance to the evergreen forest with wild animals wandering around. If the tourists want to visit this area, they need to contact the national park officer for safety reasons. The perfect time to visit the 2nd and 3rd tiered falls is during September or October because of the water level. Also, if you visit during 10 am, the sunlight will reflect on the spray of the water creating rainbows. The total height of the 2nd and 3rd level is approximately 150 meters.
