Consisting of two islands (one, you might gather, is called Saint Kitts while the other, quite obviously, is known as Nevis), there would be no avoiding this place if your goal is to visit every country in the world, but you could stay away if you want to visit every country in the world except Saint Kitts and Nevis.
Do You Care: Christopher Columbus discovered this place…as long as you are willing to overlook the Caribs, the Taíno, the Arawak, and the folks who inhabited the island before the Arawaks.
