Thungyai Huai Kha Khaeng Wildlife Sanctuaries is a vast protected area that spans multiple provinces, with the Huai Kha Khaeng section located within Uthai Thani Province. This sanctuary has been recognized by UNESCO as Thailand’s first natural World Heritage site due to its exceptional biodiversity. It is a transitional zone of diverse plant species and serves as a vital source of freshwater streams that remain pristine and unspoiled, preserving the ecological balance of the region.

A central highlight of visiting this sanctuary is learning about conservation through the Sueb Nakhasathien Memorial, honoring the former head of the wildlife sanctuary who sacrificed his life to protect this forest. Visitors can explore his preserved residence and a small museum that chronicles his work and dedication to wildlife protection. The simplicity of the site is imbued with power and inspiration, instilling a deep sense of environmental stewardship in visitors of all ages.

For nature enthusiasts and hikers, the sanctuary offers a variety of nature trails, such as the Khao Hin Daeng trail, which winds through dry dipterocarp forest and mixed deciduous forest, offering breathtaking vistas along the way. Adventurous visitors may encounter traces of rare wildlife, including tiger footprints, hornbills, and wild deer. The forest atmosphere is serene and shaded, providing a feeling of returning to the unspoiled embrace of nature.

This sanctuary serves as a living classroom for students, families, and researchers who wish to learn about environmental conservation. It is also a prime destination for wildlife photographers and birdwatchers eager to capture animals in their natural habitat. Visiting Huai Kha Khaeng is not merely a recreational experience—it is an opportunity to appreciate the importance of maintaining a large forested area that acts as a vital lung for our planet.

We invite you to experience the spirit of conservation and immerse yourself in the beauty of this World Heritage forest at Huai Kha Khaeng, where nature and human devotion meet in perfect harmony.
