Sai Yok National Park (Thai: อุทยานแห่งชาติไทรโยค) is a national park in Sai Yok district, Kanchanaburi Province, Thailand. The park, home to mountains, waterfalls and caves, is part of the Western Forest Complex protected area.
Sai Yok National Park is in the Tenasserim Hills mountain chain, 100 kilometres (62 mi) northwest of Kanchanaburi town. The park's area is 500 square kilometres (190 sq mi). The Khwae Noi river ("River Kwai") runs through the park. The park's highest peak is Khao Khwae at 1,327 metres (4,354 ft). The western boundary of the park adjoins Myanmar.
Temperatures in the park area have a wide annual range from 8 °C (46 °F) to 45 °C (113 °F). The driest time of the year here is from December to February, while the rainiest time is from May to October.
The park's major attractions are its waterfalls, including Sai Yok Yai waterfall which flows into the Khwae Noi river. Sai Yok Yai Lek waterfall lies south of Sai Yok Yai along the Khwae Noi.
The park also contains numerous caves, the largest of which is Tham Lawa with a length of 500 metres (1,600 ft). This cave complex consists of five large caverns, each containing large stalactites and stalagmites. Another cave system, Tham Daowadueng, is 100 metres (330 ft) long and was discovered in 1972. Tham Daowadung consists of eight chambers of stalactites and stalagmites.
Flora and fauna
Sai Yok's forest is primarily teak forest. During the Japanese occupation of Thailand, teak trees were felled for use as railway sleepers on the Burma Railway. The teak forest was replanted in 1954.
Animal species include elephants, tiger, barking deer, sambar deer, wild pig, gibbon, Malayan porcupine, slow loris and serow. A species of crab—the Rachinee crab, coloured red, white and blue—was discovered in the park in 1983.
Sai Yok is home to Kitti's hog-nosed bat, a rare bat species considered to be the world's smallest mammal (weighing around 2 grams). The bat was first spotted in 1973 and is found only in some limestone caves of the park (including Tham Kang Kao) and surrounding areas in Kanchanaburi Province and nearby Myanmar.
