Thung Yai Naresuan – Huai Kha Khaeng Wildlife Sanctuary has only grown in fame since it was registered as a World Heritage Site by UNESCO in December 1991. Huai Kha Khaeng covers 5,775 square kilometers, engulfing six Amphoes in three provinces. It also comprises of Thung Yai Naresuan Wildlife Sanctuary, making it the largest connected conserved forest in Thailand and the South East Asia Region. Huai Kha Khaeng was pronounced a World Heritage Site due to its five types of tropical forests extant within its borders, blessed with biodiversity. Some of the fauna are nearly extinct, including wild water buffalo, serow, leopard, Asiatic wild dog, red junglefowl cock, green peafowl and many species of forest insects. Normally, the wildlife sanctuary does not open for tourists because it is a conserved, high-sensitive area. Travelers are permitted to visit only three points of interest: headquarters of Huai Kha Khaeng Wildlife Sanctuary (where the Sueb Nakhasathian Memorial celebrates an important figure in the sanctuary’s history); Saiboe Ranger Station (where Saiboe Waterfall is located); and Huai Mae Di Ranger Station (where there are campgrounds and a nature study route.)
