Nam Tok Phlio National Park, off Hwy 3, is 14km to the southeast of Chanthaburi and is popular, as evidenced by the food stalls lining the road to the entrance. A pleasant 1km nature trail loops around the waterfalls, which writhe with soro brook carp. Also on display are the mossy Phra Nang Ruar Lom stupa (c 1876) and Along Khon chedi (c 1881).
