Namtok Phlio is a modest waterfall reached by an easy walk through forest, and what people remember is the fish: the pool below is dense with pla phluang, soro brook carp, protected within the park and habituated to being fed, in numbers thick enough that the water churns when food goes in. Vendors sell fish food at the entrance and the feeding is the main event, though the practice has obvious drawbacks for a wild population. Two monuments stand beside the pool. Rama V built a stone pyramid, Alongkorn Chedi, and a small stupa here in memory of Queen Sunandha Kumariratana, who drowned in 1880 when the royal barge capsized on the Chao Phraya - bystanders reportedly did not intervene because touching a royal person was forbidden on pain of death, and she and her daughter died. The park has other falls and forest trails.
What you actually see
- The carp - soro brook carp in dense numbers in the pool below the fall.
- The Alongkorn Chedi - the stone pyramid Rama V raised to Queen Sunandha.
- The waterfall - modest, reached by an easy 500-metre walk.
- The forest - trails and further falls in the park.
When to go
July to November for the strongest flow. The walk is easy and level in any season. Weekends bring Chanthaburi families and the fish feeding is busiest then.
Honest expectations
The waterfall itself is small - the fish and the monuments carry the visit. Feeding the carp is encouraged commercially but is not good for them. Rocks are slippery. Foreign entry fees are higher than Thai.
Nearby
Chanthaburi town and its cathedral are north-west; the Chaloem Burapha coast road runs south.
