Huai Kha Khaeng Wildlife Sanctuary

Huai Kha Khaeng Wildlife Sanctuary is located in the western region of Thailand, spanning the provinces of Uthai Thani and Tak. Covering over 2,780 square kilometers, it forms one of the largest areas of intact forest ecosystems in Southeast Asia and is recognized as a UNESCO World Heritage Site alongside the nearby Thung Yai Naresuan Wildlife Sanctuary. The landscape features dense evergreen forests, dry dipterocarp woodlands, and mountainous terrain, creating varied habitats for a diverse collection of wildlife. The sanctuary is home to iconic species such as the Indochinese tiger, Asian elephant, gaur, and numerous rare birds and reptiles. Since its establishment in 1972, Huai Kha Khaeng has played a critical role in regional conservation efforts, protecting critical wildlife corridors and preserving genetic diversity. Visitors can explore limited trails focusing on wildlife observation, birdwatching, and experiencing natural forest ecosystems. Due to its protected status and emphasis on minimal human disturbance, visitor access is carefully regulated to ensure the sanctuary’s long-term preservation. The sanctuary's remote location and pristine environment attract researchers and nature enthusiasts interested in conserving tropical forest biodiversity and witnessing some of Thailand's most elusive wildlife in their natural habitats.
