Geographically the smallest of the five regions of Thailand, Eastern Thailand contains just seven provinces. Five of its provinces border the Gulf of Thailand, and three share borders with Cambodia, all of which have at least one international border crossing Aranyaprathet being the busiest.
While Pattaya is the original mass tourism destination, the islands of Ko Samet and Ko Chang also turned into popular beach destinations. On the other hand, the islands at the eastern tip of the region, until recently very difficult to get to, are some of the most scenic and untouched in the country.
