15. Nauru: 160 tourists
The least visited country on this list, Nauru only gets approximately 160 tourists each year (have you even heard of it?). Those intrigued by WWII history are welcome to discover the last vestiges of Japanese occupation on the small island, and view the impressive skeletal remains of its mining infrastructure.

16. Libya: 6,250 visitors
You must have already noticed a pattern in this list, and an obvious one at that. War torn? Civil distress? Tourists aren’t going. This is the same for Libya, which though it is the seventeenth largest country in the world, only sees about 6,250 visitors each year. Those that dare brave the unrest discover mind-blowing attractions like Leptis Magna, which was a major city of the Roman Empire, and Cyrene, founded by the Greeks in the seventh century, which is still a Libyan archeological site today. As only ten percent of the country is not unbearably dry desert, most visitors tend to head to more northern regions on the Mediterranean sea, where the climate is more manageable.
