Nakhon Ratchasima (นครราชสีมา), usually referred to as Korat or Khorat (โคราช), is the capital city of the Province by this name, and is also the second largest city in the Isaan (Northeast) region of Thailand.
Hwy 2 (Bangkok to Nong Khai) runs through the city as does the northeast railway line which splits in the east of the city: one line runs up to Nong Khai and the other, to Ubon Ratchathani. And there are buses which run to just about every city in the northern, northeastern and eastern regions. You can even get buses to Vientiane in Laos and to the Cambodian border at Aranyaprathet. The city itself has a population of around 200,000 (Nai Muang district), but the entire urban sprawl of the Nakhon Ratchasima metroplitan area (Muang Nakhon Ratchasima) has a population approaching half a million. Despite the size of the city, it is not a favoured holiday destination for the average foreign traveller. Instead, visitors are more likely to base themselves in the city as they visit nearby tourist destinations such as Khao Yai national park, Phimai and Phanom Rung.
