Pak Chong District

Pak Chong is the westernmost district of Nakhon Ratchasima Province, north-eastern Thailand. In the past this area was a part of Tambon Khanong Phra, Chan Thuek district (which is now Sikhio district). In 1949 Ban Pak Chong was upgraded to be Tambon Pak Chong. It was upgraded to a minor district effective January 1, 1957, consisting of the four sub-districts Pak Chong, Chanthuek, Klong Dan and Mu Si. It was finally upgraded to a full district in July 1958. In the reign of King Chulalongkorn (Rama V) during the construction of the north-eastern railway through the area, the Nok Yung and Noi mountains were blasted through to make a channel (Chong in Thai) for the railway. Then the people named the village Pak Chong, meaning mouth of the channel. The district is the gateway to the Northeast (Isan) of Thailand from the central region, as the main pass through the Sankamphaeng Range mountainous area is located in the southern section of this district. The southern parts of the district are part of Thailand's first and largest national park, Khao Yai. Within the park is the origin of the Takhong River, a tributary of the Mun River. The Takhong is the main water resource of Nakhon Ratchasima city. [Source: Wikipedia]
