The park was built on the former site of the Thailand Tobacco Monopoly factory.
The forest park extension uses an irrigation system specifically designed to filter urban water runoff through natural wetlands.
The project is a collaboration between the Treasury Department and the Arsom Silp Institute of the Arts.
The elevated walkways stretch for over 1.6 kilometers, connecting different sections of the forest park.
The park serves as a flood mitigation reservoir for the surrounding urban areas during monsoon season.
Benchakitti Park is a massive urban green space in Bangkok, expanded significantly in 2022 to encompass 450 rai (72 hectares) of integrated forest and wetland habitats. The park features a complex network of elevated skywalks that weave through a reforested zone designed to function as a carbon-absorbing urban lung. A large central lake serves as a retention basin for flood management, surrounded by dedicated bicycle tracks and jogging paths. The northern sector maintains the original formal design, while the southern extension highlights native aquatic plants and riparian ecosystems. Visitors can navigate between the original park and the new forest extension via a scenic, elevated pedestrian bridge. The site was formerly the location of a tobacco factory, which has been repurposed into a multi-purpose museum and sports complex. The landscape design emphasizes biodiversity, attracting numerous species of local birdlife and aquatic creatures. It acts as a major ecological buffer in the dense Khlong Toei district.

Use the elevated skywalks to navigate the forest area, as ground-level paths can become muddy during the rainy season.
Bring a refillable water bottle, as the park covers a large area with limited shaded food vendors in the interior.
The park's immense size means it can take over an hour to walk from one end to the other, so plan your entry point accordingly.
Avoid visiting during the midday heat, as the newly planted forest sections have limited mature canopy cover.
Maintain noise discipline near the forest areas to avoid disturbing local birdlife; littering is strictly prohibited.
