Isan covers an area of 160,000 km and much of the land is given over the farms and paddy fields as agriculture is the main economic activity. The region of Isan has a strong, rich and individual culture. Examples of this can be found in the folk music, called mor lam, festivals, dress, temple architecture and general way of life.
The main regional dialect is Isan, which is actually much more similar to Lao than central Thai. Unfortunately, because the rainfall is often insufficient for crops to grow properly, Isan is the poorest region of Thailand, and many people leave the province to seek their fortunes in the bustling metropolis of Bangkok.
The average temperature range is from 30.2 C to 19.6 C. The highest temperature recorded was a sweltering 43.9 C, whilst the lowest was a freezing -1.4 C. Unlike most of Thailand, rainfall is unpredictable, but it mainly occurs during the rainy season, which takes place from May to October.
Although completely unique, Isan food has adopted elements of both Thai and Lao cuisines. Sticky rice is served with every meal and the food is much spicier than that of most of Thailand.
Popular dishes include:
som tam - extremely spicy and sour papaya salad
larb - fiery meat salad liberally laced with chilies
gai yang - grilled chicken
moo ping - pork satay sticks
Isan people are famous for their ability to eat whatever happens to be around, and lizards, snakes, frogs and fried insects such as grasshoppers, crickets, silkworms and dung beetles often form a part of their diet.
Both men and women traditionally wear sarongs; women's sarong often have an embroidered border at the hem, whilst those of the men are chequered. Much of Thailand's silk is produced in Isan, and the night markets at many of the small towns and villages are good places to find a bargain.
There is no major airport in Isan, but the State Railway of Thailand has two lines and both connect the region to Bangkok. This is also a good place to enter Laos via the Thanon Mitraphap ("Friendship Highway"), which was built by the United States to supply its military bases in the 1960s and 1970s. The Friendship Bridge - Saphan Mitraphap - forms the border crossing over the Mekong River on the outskirts of Nong Khai to the Laos capital of Vientiane.
