Huai Kha Khaeng Wildlife Sanctuary is one of most interesting wildlife watching location in Thailand. Due to relatively clear visibility through the forest and abundance of all sorts animals it is very easy to spot wildlife. The sanctuary is home to largest population of tigers in Thailand, other relatively common species are banteng, elephants and leopards. Although being one of best bird-watching destinations it is quite unknown to many birders.
Inscribed as Wildlife Sanctuary in 1974, together with adjacent Thung Yai Wildlife Sanctuary both sites are the largest protected wildlife area in mainland Southeast Asia. It is located in the Dawna Range northwest of Thailand, covering 2780 km² mainly within Uthai Thani province but also Kanchanaburi and Tak provinces, bordered by Thung Yai Wildlife Sanctuary to the west. Huai Kha Khaeng and Thung Yai were jointly added to the UNESCO World Heritage List in 1991.
Huai Kha Khaeng is mainly hilly, consists of evergreen hill forest with Eleocarpus dominating the river banks, semi-evergreen, deciduous and bamboo forests. The sanctuary has several large rivers surrounded by grassland. The sanctuary is one of Thailand's least accessible and least disturbed forest areas.
The species found in the sanctuary are mix of four different biogeographic zones; Indo-Burmese, Indo-Chinese, Sundaic and Sino-Himalayan. Many of species found here are rare, endangered or endemic. Around one-third of all mainland Southeast Asia's known mammal species sad to be represented in the sanctuary.
Most common mammals in the park with almost guaranteed sighting during couple of days trips are four deer species (Sambar deer, barking deer, Eld's deer and Indian hog deer), long-tailed macaque, Asian palm civet and boar. There is quite good chance to spot bantengs and elephants on the first watchtower 7 km east of headquarters. Huai Kha Khaeng is probably the best place in Thailand to see bantengs, another good location is Kui Buri National Park. Leopards are seen relatively often, but one may need up to weeks patient search to eventually see one. Tigers are relatively common, but sighting is quite rare. Tiger pawn prints can be seen along the trails and dirt roads regularly.
The sanctuary is an excellent place to see various bird species, underestimated by birders probably due to it's remote location. Green peafowls, crested serpent eagles, red-billed blue magpie, common iora, white-bellied woodpecker, orange-breasted trogon, black-headed woodpeckers are few of many very common bird species found around headquarters and along the dirt roads.
