Nam Nao National Park

Nam Nao is a large protected area in Phetchabun Province featuring different forest types including dipterocarp, evergreen, and pine forests along with grasslands situated around 800 meters in elevation. The park offers marked hiking trails of varying lengths that take visitors through these different forest zones and open spaces.

The forest was designated as a national park in 1972 to protect its ecosystems and spans territories across two provinces, Phetchabun and Chaiyaphum. This protection gave the land official status to preserve the natural environment for the future.

The area was home to hill tribes who lived in harmony with the forest and shaped the landscape through sustainable practices over generations. Visitors walking through the forest today can sense how the land reflects this long coexistence between people and nature.

The hiking trails are clearly marked and range from short walks to longer treks, so visitors can choose based on their fitness level and time available. The best time to visit is during the drier months when the paths are easiest to navigate.

The area is home to one of Thailand's longest caves, Tham Yai Nam Nao, which extends deep into the mountainside and contains impressive underground rock formations. The cave provides a different kind of experience for visitors compared to walking through the forest above.
