The Banyan tree at Sai Ngam is estimated to be over 350 years old.
The aerial roots have grafted into each other over time, creating a singular, massive organism rather than a collection of separate trees.
The park is maintained by the local municipality to preserve the structural integrity of the ancient tree's root system.
The extensive canopy creates a microclimate significantly cooler than the surrounding open areas in Phimai.
Sai Ngam is a massive banyan tree grove covering approximately 25,000 square feet, characterized by a dense, interconnected network of aerial roots that form a natural canopy. The park is home to a single, centuries-old Banyan tree (Ficus benghalensis) that has propagated over generations to create a labyrinthine forest appearance. The site is situated along the banks of the Mun River, which provides a natural moat and irrigation for the root system. Visitors walk along wooden boardwalks constructed beneath the interlocking branches to navigate the expansive, shaded environment. The site is managed as a public park and is considered a significant local botanical landmark in the Phimai District.
From the center of the boardwalk where the branches form a natural archway over the path.
Bring mosquito repellent, as the dense shade and river proximity create an ideal environment for insects.
Stick to the marked wooden boardwalks to avoid damaging the delicate root surface and to prevent tripping.
Visit during the morning to see local vendors selling traditional Thai snacks and crafts near the entrance.
Do not feed the local wildlife, as it encourages aggressive behavior, and avoid veering off the boardwalks.
Maintain a quiet volume, wear modest clothing as it is a site held in local reverence, and do not climb or sit on the exposed tree roots.
