Ratanakiri is located in Cambodia's far northeast bordered by Laos to the north, Vietnam to the east, Mondulkiri to the south, and Stung Treng to the west. This rural rugged province is a 70% ethnic minority, which are known as "Chunchiet". Ratanakiri was as recently as 2002 seriously off the beaten track but has since been "discovered" step by step.
Still, while you won't get any bragging rights for coming here, it's well worth the effort to do so, and once you get away from it's capital Banlung you won't run into too many other tourists. So Ratanakiri is still a remote province in Northeastern Cambodia worth to visit. The word "Ratanakiri" itself is a derivative of two Cambodian words, which are combined to mean "place of gems and mountains." The word comes from the Sanskrit words Ratna (gem) and giri (mountain).
