Namtok Phlio National Park

Namtok Phlio National Park is a 134.5 sq km protected area in Chanthaburi Province, eastern Thailand, about 14 km southeast of Chanthaburi town. Centered on the perennial Phlio Waterfall with clear pools inhabited by soro brook carp, the park combines evergreen forest, historic royal memorials including Alongkorn Chedi, and nature trails. Established in 1975, it is notable for its accessible waterfall, cultural history linked to King Rama V, and biodiversity.

Visitors can expect a forested national park centered on Phlio Waterfall, a multi-tiered cascade flowing year-round into clear pools where large soro brook carp are visible. The area includes shaded forest trails, boulders and swimming areas near the falls, the historic Alongkorn Chedi (1881) and Phra Nang Ruer Lom Stupa on hillside viewpoints, plus visitor centre, picnic areas and nature study paths. The environment is humid tropical forest with well-maintained walkways and steps around the waterfall.
