I-san - The Northeast of Thailand

I-san, Thailand's northeast region, is an often-overlooked part of the country. There's no coastline, so there are no beaches to draw those seeking sand and sea. Isan, however, is a multicultural area where Laos, Cambodia and Thailand meet. Isan is mainly an agricultural region and has a rich history and magnificent natural scenery. The region consists of 20 provinces and is Thailand's largest region and takes up almost a third of Thailand’s land mass. The region is located on the Korat Plateau, bordered by Cambodia to the southeast and by the Mekong River (along the border with Laos) to the east and north. To the west it is separated from northern and central Thailand by the Phetchabun Mountains.

The vast sandstone Korat Plateau, which is about 200 m above sea level, is rich in culture and historic sites from the days when the Khmer Empire held sway over the region. In the 9th century AD, the Korat Plateau came under Cambodian control, which was to endure until the end of the 13th century. It was during this period that the region’s splendid Khmer temples were built. The magnificent stone temples at Phanom Rung and Phimai, which once stood on a road linking the plateau with the Khmer capitol of Angkor, have been evocatively restored.

To the north, at Ban Chiang, is a site that have revolutionized archeologists’ views of prehistoric Southeast Asia. The northeast is now thought to be one of the first areas in the world where rice growing, bronze making, and silk weaving were pioneered. Silk weaving has flourished again since the mid-20th century and modern-day weaving villages sell a wide range of silk and cotton goods.

With its source in the Tibetan Himalayas, the Mekong River reaches Chiang Khan in northeast Thailand. From here the river forms the border with Laos for 750 km until it flows into Cambodia. The Mekong River valley’s relatively fertile land remains one of the most beautiful, unspoiled regions in the country. Furthermore, due to its distance from Bangkok, the area has escaped widespread development.

Fascinating historical sites, many national parks and wildlife reserves, unspoiled mountain areas, distinctive sandstone formations and rural villages color the landscape. The four major cities of Isan, also known as the "big four of Isan", are Khorat, Khon Kaen, Udon Thani and Ubon Ratchathani
