Tham Pla-Namtok Pha Suea National Park

Tham Pla-Namtok Pha Suea National Park is a protected area in Mueang Mae Hong Son District, Mae Hong Son Province, northern Thailand, covering about 488 square kilometres near the Myanmar border. Established in 2000, it is known for Tham Pla Cave with its stream of soro brook carp, the multi-tiered Pha Suea Waterfall, limestone mountains, mixed deciduous and evergreen forests, and watershed forests of the Pai River basin.

Visitors can explore a forested limestone mountain park with two main attractions: Tham Pla Cave, a short cave with a clear stream inhabited by large numbers of soro brook carp (Tham Pla fish) and stalactites, and Pha Suea Waterfall, a wide multi-tiered waterfall flowing over limestone terraces. The park offers shaded nature trails, picnic areas, viewpoints, a visitor centre, and opportunities for photography, nature walks and observing fish in the cave stream.
