Namtok Ta-Yai is a small, natural tiered waterfall located in the Phaya Yen sub-district of Pak Chong. The site features a series of limestone cascades that flow into shallow, wading-friendly pools. Surrounded by dense secondary forest and local farmland, the area is primarily utilized by domestic tourists for picnics and river swimming. The water flow is seasonal and highly dependent on rainfall in the Khao Yai mountain range periphery.
