Ton Sak Yai National Park

Ton Sak Yai is a national park in Uttaradit Province with mountain ranges, dense forests of varied types, and multiple waterfalls scattered throughout the protected area. Bird watching is popular here because of the large number of species that make this place their home.

The area was first protected as a forest reserve in 1990, then became an official national park in 2003. Later it was renamed to honor a special ancient tree found within its boundaries.

The park holds deep meaning for local people who practice traditional ways of life and care for the forest as part of their heritage. You can see how residents maintain daily connections with the natural world around them.

Wear sturdy shoes and bring plenty of water when exploring the trails, as the terrain is hilly and the hikes can be demanding. Plan your visit during cooler months for the most comfortable experience.

At the heart of the park stands an ancient teak tree thousands of years old, a living witness to countless generations passing through the forest. Its remarkable age and size made it so important that the entire park was eventually named after it.
