Wilderness Landscape & Natural Heritage
Ton Sak Yai National Park is located in the Uttaradit Province of northern Thailand and was established in 1989 to protect one of the world's largest and oldest teak trees, known as Ton Sak Yai, which stands more than 50 meters tall and over 1,200 years old. The park covers approximately 208 square kilometers of mountainous terrain, primarily consisting of dense mixed deciduous forests. Its diverse ecosystems host a variety of wildlife including deer, wild boar, gibbons, and numerous bird species. The park's terrain features rolling hills, limestone cliffs, streams, and several seasonal waterfalls which attract both casual visitors and avid outdoors enthusiasts. Popular activities include hiking along well-maintained trails, wildlife watching, and visiting historical sites related to traditional livelihoods and forestry. Ton Sak Yai National Park serves as an important conservation area preserving native flora and fauna, while providing opportunities for educational and cultural experiences. Visitors are often drawn to the giant teak tree, which is considered a natural landmark, alongside peaceful picnic areas and viewpoints for forest landscapes. The park’s accessibility from Uttaradit town makes it a favored spot for both local and international visitors interested in ecotourism and experiencing Thailand’s protected forest environments.
