(Mae Hong Son)

Mae Hong Son's nickname is "the city of three mists". It is hemmed in by the high mountain ranges of the Shan Hills and is the most mountainous province in Thailand, occupying 12,681 square kilometres (4,896 sq mi).[5] The province is often covered with mist. Mae Hong Son town was originally established in the early 19th century as an elephant training camp as ordered by the then King of Chiang Mai. As of 2012, Mae Hong Son was the poorest province in Thailand.[6]


Mae Hong Son province was formerly part of Mawkmai State, one of the Shan States which had been founded in 1767 by Hsai Khiao, from a noble family of Chiang Mai.[7]

As a result of the Anglo-Siamese Boundary Commission of 1892–1893, Mae Hong Son District was ceded to Siam,[8] but the adjacent Möngmaü and Mehsakun trans-Salween Districts also claimed by Siam (as territories on the eastern side of the Salween River), were kept as part of British Burma.[9]


The Thai government, to solve persistent water shortages in the central region, have proposed a 70.7 billion baht plan to divert some 1.8 billion m3 of water annually from the Yuam River to the perennially underfilled Bhumibol Dam. Several of the province's districts would impacted. As part of the plan, the Royal Irrigation Department (RID), would build 69 metre high dam with a storage capacity of 68.7 million m3 constructed on 2,075 rai of forest land, together with a pumping station on a separate 55 rai plot and a 61.5 kilometre-long tunnel passing through 14 villages. The inhabitants of the area—primarily Karen tribes people—largely oppose the project. In December 2019, the RID submitted a second environmental impact assessment (EIA) to the Office of the Natural Resources and Environmental Policy and Planning (ONEP). ONEP rejected the EIA for the second time due to concerns about forest destruction, tunnel rock waste, and compensation issues.[10]


Ethnic diversity[edit]

Shan people is the largest population group in the province. They migrated from Shan State in Myanmar. Further there are seven hill tribes which consists of 63% of the provincial population: Karen, Lahu, Lisu, Lua, Miao, Chinese Yunnan and Pa-O people.

The Karen are not a single group, but rather a mix of closely related tribes. Among the smallest of the Karen tribes in Thailand are Kayan Lahwi. This group's women are recognized by the large brass rings they wear around their necks. Population density is 22 persons per km2, the lowest of all provinces.[11]



Most inhabitants, 77.5%, are Buddhists, followed by Christians at 20.9%, and Muslims at 0.5%. About 1.1% believe in animism and other religions.[13]



Mae Hong Son province is approximately 924 kilometres (574 mi) north of Bangkok by road. To the north and west it connects to a total of three states in the Union of Burma, namely the southern portion of Shan State, Kayah State, and Kawthoolei State, via the Dawna Range, and the Salween and Moei Rivers. These formations serve as natural boundaries between the countries. To the south, it borders the district of Tha Song Yang and Tak, via the rivers Yuam and Ngao, which serve as a provincial boundary. To the east it borders the districts of Wiang Haeng, Chiang Dao, Mae Taeng, Mae Chaem, Hot and Omkoi in Chiang Mai province, via the central and east sections of the Thanon Thongchai mountain ranges, which serve as a boundary between the two provinces.

Every district in Mae Hong Son province shares a common border, measuring approximately 483 kilometres in total length, with Myanmar. The common border consists of approximately 326 km (203 mi) of land boundary and 157 km (98 mi) of river boundary (not counting the Salween, 127 km (79 mi), and Moei, 30 km (19 mi)).[14]


Most of the areas of Mae Hong Son province are the complex mountain ranges of the Thai highlands, parts of which are still covered with rainforest. The total forest area is 10,915 km2 (4,214 sq mi) or 85.5 percent of provincial area.[1]

The Daen Lao Range, in the northernmost portion of the province, marks the northern boundary between Thailand and Burma, while the Dawna Range in the west serves as the boundary between Thailand and Burma. The Thanon Thongchai Range in the east of the province serves as the boundary between the provinces of Mae Hong Son and Chiang Mai. The highest point of the province is Doi Mae Ya (ยอดเขาแม่ยะ), in the Pai District in the province's northeast, at 2,005 metres (6,578 ft) elevation.[15]

The provincial seal, Rup chang nai thong nam (รูปช้างในท้องน้ำ), meaning 'image of an elephant in a body of water', is a reference to the training of wild elephants for battle and various types of animal labour. "Rup chang nai thong nam" was selected as the provincial seal because it refers to Mae Hong Son's founding, which began with Lord Kaeo of Ma being sent to capture elephants for the Lord of Chiang Mai (1825–1846). Once in Mae Hong Son, he gathered the scattered Shan settlements to establish two main villages, Ban Pang Mu and Ban Mae Hong Son, that would be ruled by their elected leaders.
