This waterfall is located in the lower region of the national park, which has opened up an adventurous tourism route called "Tracing the Free Thai Movement: Exploring Tad Hong." This trail once served as a pathway for the Free Thai Movement that connected Loei Province to Phetchabun Province during World War II, allowing General P. to evade Japanese forces. The waterfall itself stands at a height of 40 meters, and when the water cascades down the cliffs into the pool below, it produces a thunderous roar, leading to its name "Tad Hong Waterfall." Along this route, there are also several attractions, including Huai Wu Waterfall, White Sand Beach, Stone Rapids, prehistoric rock paintings, and the Phu Lat Muang viewpoint, where visitors can enjoy stunning vistas of the surrounding landscape.
