The proud city of Khon Kaen sprawls on the east side of the same-named province and serves as a major hub of education, transport and commerce for the Isaan region. Most foreigners who pass through are either here on business or to catch a bus, but travellers looking to practice their Thai while getting a feel for a big, non-touristy Thai city will find enough to do for a couple of days. What Khon Kaen lacks in charm, it makes up for in energy.
