Located approximately 500 meters from the Park's office, this waterfall flows over rocks into 11 huge pools, each with their own name, such as Wang Thewada, Wang Sok, and Wang Chan. Another 3-tiered waterfall originating from a high-altitude cliff called Namtok Huai Sa-de is located some 1.2 kilometers from the Park’s office. Apart from visiting waterfalls, adventurous visitors can trek to the peak of the Phanom Bencha Mountain, which is 1,397 meters high. This challenging and memorable activity takes at least 3 days and passes streams, waterfalls, caves and view points on high cliffs.
