Khon Kaen is the commercial, administrative, and educational center of the Northeast that is often used by travelers as a base for visiting many parts of upper Isan.
Khon Kaen is the commercial and political center of Northeastern Thailand and is well known for the high quality silk that is produced in the province. Located in the heart of Isan, Thailand’s northeast region, Khon Kaen has been one of the fastest growing areas in Thailand.
In addition to containing some fascinating historical and archaeological sites, Khon Kaen is also an excellent place to watch the production of Mudmee Silk or participate in outdoor activities within one of its several animal reserves or national parks.
