The marsh is part of a larger Ramsar site, an international wetland designation for conservation.
The landscape is defined by its dramatic backdrop of limestone massifs that rose from the sea millions of years ago.
The boardwalk is elevated to protect the sensitive marsh floor and allow water to flow naturally beneath it.
It is a hotspot for birdwatchers, especially for spotting the purple swamphen and various species of herons.
The name 'Sam Roi Yot' translates to 'three hundred peaks,' referring to the karst formation surrounding the wetland.
The water levels in the marsh can fluctuate significantly depending on the annual monsoon rainfall.
Bueng Bua Wood Boardwalk is a wooden walkway extending over a vast freshwater marsh located within the Khao Sam Roi Yot National Park. It serves as a primary viewing point for the park's expansive wetlands, which are framed by jagged limestone karst mountains. The structure consists of a kilometers-long raised platform that allows visitors to traverse the center of the marsh without disturbing the aquatic ecosystem. The area is a critical habitat for a variety of migratory birds and unique lotus-like vegetation. Visitors can observe local wildlife such as waterfowl and monitor lizards from the safety of the path. The wooden planks are periodically subject to weathering, and sections may be cordoned off for maintenance as required by the park management. The site acts as a key component of the Ramsar-designated wetland system within the national park. It provides direct, elevated access to the heart of the freshwater swamp environment.

Bring a hat and high-SPF sunscreen, as the boardwalk is almost entirely exposed to direct sunlight.
Carry binoculars if you are interested in birdwatching, as wildlife often remains at a distance from the path.
Visit quietly and avoid loud talking to increase your chances of seeing elusive local bird species.
Do not attempt to walk off the planks into the swamp mud, as the terrain is unstable and ecologically sensitive.
May be subject to temporary closures during the rainy season if the wooden structure becomes submerged or unsafe.
Stay on the boardwalk at all times; do not litter; keep noise levels low to avoid disturbing the local fauna.
