Isaan, making up Thailand's northeast region, is the country's least visited tourist area. It's also the poorest, with many making their living off the land.
Much of the region is flat farming land. There are often trees scattered about that give a certainromantic feel to the landscape - it doesn't feel too 'harsh' as there always seems to be a tree to find shade!
