Tad Hong Waterfall is located in the Phu Kradueng National Park; it is a large 3-tiered waterfall originating from the Nam Phong River, which flows down from Phu Kradueng in the northwestern valley. Both sides of Tad Hong are very steep rock cliffs, when the waterfall hits the ground below, there will be a loud rumbling sound in the forest. With a relatively difficult journey, it is considered that very few tourists have the opportunity to visit; for this reason, this waterfall is very pure and natural. As the waterfall passed through the wide tiered rock cliffs, it caused a loud rumbling sound. From the waterfall area, a bare mountain line can be seen in front. Tad Hong Waterfall is approximately 20 kilometers from the National Park Office.
