Udon Thani (อุดรธานี, also Udorn Thanee) is a city in the Isaan region of Thailand. Often referred to as simply Udon or Udorn (อุดร), the city should not be confused with Ubon — Ubon Ratchathani in southeastern Isaan.
Founded in the 1890s by Prince Prajak Silapakom, Udon Thani is the 7th largest city in Thailand.
Udon had a USAF airbase during the Vietnam War that increased its wealth and importance. Surrounded by one of the major agricultural areas of the country, Udon Thani has become a regional hub for agriculture, commercial distribution, shopping and a fledgling tourism industry.
Because of the US presence (the airbase until 1976, a U.S. consulate until 1995, and currently, a Voice of America radio station) many Thais were well-paid and learned English, making them more marketable to foreign labour recruiters. Udon has a large number of its citizens who have worked or are working overseas, particularly in Middle East oil fields. This has contributed both to the wealth of the area and its desirability as an expat destination. More than 5,000 expats from Europe, Australia and North America have settled in the area.
- 1 Udon Thani Airport (UTH IATA). Has several 50 min daily flights to Bangkok (Suvarnabhumi [BKK]) (Thai Airlines: around 2,500 baht) or (Don Mueang [DMK]) (Air Asia from 500 baht and Nok Air from 1,250 baht if booked well in advance). There are also direct flights to Chiang Mai, Loei and Phuket (Air Asia flies to Phuket with tickets often around 1,000-1,200 baht, which is comparable to a 2-night bus/train trip via Bangkok).
To get to the city there is a limousine service (actually a minibus) for 80 baht/person that will drop you and other passengers at the location of your choice. Minibus tickets are available in the booth just to the right as you leave the terminal building. If there are more than two of you, it may be cheaper to call a taxi (Tel. +66 42 323239) or to use Grab ride-hailing service, which (as of January 2019) costs 160 baht to/from central Udon. Taxis are not permitted to wait for passengers at the airport, but some do it anyway, asking 200-400 baht for the 4 km journey. Some hotels have pickup services and may take an extra passenger or two if space permits. Some long distance buses to Khon Kaen were seen in the airport, with numerous people boarding them. No local Udon Thani songthaews have been seen near the airport.
If you are travelling on to Nong Khai, there is a bureau straight ahead of you when you get to the arrivals hall which sells minivan tickets to Nong Khai. They have a minibus which meets most flights and for 200 baht they will load you into a minivan. It takes one hour to reach Nong Khai and if you ask the driver he will take you to your hotel, or drop you off at the Thai side of the Friendship Bridge. You can then proceed into Laos.
