Pak Chong (Thai: ปากช่อง, in Thai pronounced as /pàːk tɕʰɔ̂ŋ/; ปากช่อง, in Lao pronounced as /pàːk sɔ̄ŋ/) is the westernmost district (amphoe) of Nakhon Ratchasima province, northeastern Thailand, and the main point of entry into Isan as the main road and rail lines cross the Dong Phaya Yen Mountains into the region. It is a popular tourist destination, especially among weekenders from Bangkok, and is home to many resorts and touristy attractions, in addition to the main entrance into Khao Yai National Park.
HistoryAt the time, the village was part of Tambon Khanong Phra of Amphoe Chan Thuek, which became renamed as Tambon Chanthuek of Amphoe Sikhio in 1939. In 1949, Ban Pak Chong was upgraded to subdistrict (tambon) status. It was upgraded to a minor district (king amphoe) effective 1 January 1957, consisting of the four subdistricts Pak Chong, Chanthuek, Klong Dan, and Mu Si.[3] It was upgraded to a full district in July 1958.[4]
The forests of Dong Phaya Yen were rapidly cleared following the construction of Mittraphap Road in 1955, which vastly opened up access to the area. Most of the land became dedicated to agriculture, particularly plantations of maize and cassava, following government incentives.[5] Only scattered forested hills remain, leading up to Khao Yai National Park on the district's southern edge, which was established as the country's first national park in 1962. Proximity to the national park would later contribute to the district's development as a tourist destination, especially in the 2000s to 2010s.
The local government of Pak Chong town was first established as a sanitary district (sukhaphiban) in 1956. It was established as a subdistrict municipality (thesaban tambon) in 1981 and became a town municipality (thesaban mueang) in 2005.
Pak Chong is the biggest district of Nakhon Ratchasima by area, at . It is bordered by Nakhon Ratchasima's districts of Sikhio to the northeast and Sung Noen, Pak Thong Chai and Wang Nam Khiao to the east, Prachantakham district of Prachin Buri province and Pak Phli and Mueang Nakhon Nayok districts of Nakhon Nayok province to the south, and Muak Lek of Saraburi province to the west and northwest.
The district lies within the hills of the Dong Phaya Yen Mountains, which form the southwestern boundary of the Isan region (northeastern Thailand). The district is limited in the east by the Khorat Cuesta, which forms a ridge marking the edge of the Khorat Plateau,[6] while the ridge of the Sankamphaeng Mountains, covered by Khao Yai National Park, forms its southern border. The stream Khlong Muak Lek, flowing northwards from the mountains, marks its western boundary. The Lam Takhong, also originating in Khao Yai, flows northwards through the district, passing through Pak Chong town and emptying into the Lam Takhong Dam reservoir in the district's northeast.
Pak Chong district is the main entry point into Isan from the central region, as the primary routes of both road and rail traverse the district from west to northeast through the Dong Phaya Yen pass. Pak Chong town lies slightly north of the district's physical centre, while its southern area, abutting Khao Yai National Park and generally also known as Khao Yai, has developed into a spread-out resort area. The town of Klang Dong—meaning 'middle of the jungle'—lies southwest of Pak Chong town along the road and railway, to the district's west.
Tourism is also a large contributor to the economy, with tourists coming to visit Khao Yai National Park as well as other attractions in the wider Khao Yai area to the south of the district. Agritourism draws visitors to major farms and vineyards, Khao Yai being one of Thailand's two wine-producing regions along with Hua Hin. Numerous resorts, golf clubs, cafés, art galleries and shopping centres are scattered throughout the area, many of which feature novelty European-themed architectural styles and cater to domestic tourists, mainly the Bangkok middle-class.[9] Development of holiday properties is a major driver of real estate development in the Khao Yai area.[10]
The Royal Thai Army's special combat training camp is in Nong Taku, Khanong Phra subdistrict. It trains five classes of 300 soldiers each per year in the 56-day training course.[11]
Mittraphap Road, designated National Highway 2, is the primary highway that carries traffic between Bangkok and the entire Isan region. It links Pak Chong westward to Muak Lek and northeastward to Sikhio. While the original route passed through the town of Pak Chong and continues to serve as its main thoroughfare, the main highway now bypasses the town to the south. The under-construction Motorway 6, which is scheduled to open in 2022, will feature an access ramp for Pak Chong and Khao Yai on Thanarat Road (Highway 2090), the main access road linking the town to the national park's main northern entrance.
The State Railway of Thailand's Northeastern Line passes through the district with stations at Klang Dong, Pang Asok, Bandai Ma, Pak Chong, Sap Muang, Chanthuek and Khlong Khanan Chit, Pak Chong railway station being the only class 1 station. As of 2022, the railway is being upgraded to double-track, along with construction of the Bangkok–Nong Khai high-speed railway, which will have a station at Pak Chong.
Some long-distance trains from Bangkok to Udon Thani or Nong Khai and all trains to Ubon Ratchathani stop at Pak Chong,[12] [13] as well as the local trains connecting Kaeng Khoi Junction with Nakhon Ratchasima railway station and beyond.
Pak Chong is divided into 12 sub-districts (tambons), which are further subdivided into 219 administrative villages (mubans).
