Huai Yang Waterfall

Huai Yang Waterfall is a forested multi-tiered waterfall inside Namtok Huai Yang National Park in Huai Yang Subdistrict, Thap Sakae District, Prachuap Khiri Khan Province, southern Thailand. It is the park's namesake attraction, featuring five main tiers with clear pools set in evergreen forest of the Tenasserim Hills. The waterfall is notable for its accessible nature trail, seasonal water flow and protected watershed near the Myanmar border.

Visitors can expect a 5-tier forest waterfall with small cascades and clear pools surrounded by dense evergreen and mixed deciduous forest. A marked nature trail leads through the tiers, with viewpoints, wading areas and shaded picnic spots. The setting is natural and quiet inside the national park, with opportunities for short trekking, photography and observing forest flora and birds. Water volume varies seasonally, strongest during and after the rainy season.
