Ton Sak Yai Forest Park is a world-class natural learning center and a prominent tourist destination in Uttaradit Province. The history of this park began with the discovery of a colossal golden teak tree by an exploration team in 1927. At that time, the teak stood magnificently in the heart of a lush forest. Later, the area was established as a forest park to protect and conserve this invaluable golden teak from destruction. Today, Ton Sak Yai attracts immense interest from scholars and tourists alike as a rare natural wonder of the world.

The physical characteristics of this giant teak tree were originally over 47 meters tall, though it currently stands at approximately 37 meters after its top was damaged by a severe storm. Its trunk is so massive that it requires more than 10 people holding hands to encircle it. Scientific research reveals that this tree is over 1,500 years old, making it the oldest recorded teak tree in history. Its thick bark and deep-reaching root system signify strength and survival through countless natural crises over many eras. Standing before a living entity that has existed for a millennium allows visitors to truly feel the immense power and grandeur of nature.

Within the forest park, there is more than just the giant teak tree; it also features well-organized nature trails. Visitors can explore various plant species and breathe in the pure air within the fertile forest. An elevated wooden walkway has been constructed around the giant teak tree to prevent visitors from stepping directly on the ground, which could impact the tree's root system. This management style demonstrates a deep commitment to sustainable natural resource conservation. Additionally, there are educational exhibitions regarding golden teak, which is an economically and historically significant timber for Thailand.

Ton Sak Yai Forest Park serves as a living natural museum and a symbol of great pride for the people of Uttaradit. This site helps raise public awareness about the importance of forest and environmental conservation for future generations. Visiting this park is a journey to learn about the history of a tree species that has stood alongside the Thai land for over a thousand years.
