Bueng Bua Boardwalk

Bueng Bua Boardwalk is a 1.1-kilometre wooden boardwalk over the Bueng Bua freshwater marsh inside Khao Sam Roi Yot National Park in Sam Roi Yot District, Prachuap Khiri Khan. The wetland is known for seasonal lotus blooms, diverse birdlife and open views of limestone hills. An observation tower at the end offers panoramic views. It is a managed nature attraction focused on low-impact sightseeing, photography and birdwatching within Thailand's first coastal national park.

Visitors can walk a flat 1.1 km wooden boardwalk extending over a freshwater marsh and lotus lake surrounded by reeds and limestone hills. The route leads to an observation tower with panoramic views of the wetland and park landscape. The setting is open and exposed with little shade, offering opportunities for sightseeing, photography and birdwatching. Interpretive signs are placed along the walk and the area is quiet, with seasonal lotus flowers most visible in the cooler months.
