This tiny island is one of those underrated, almost unknown destinations that is truly a hidden gem. Nicknamed the "unspoiled queen of the Caribbean," it is easy to see why the locals want to keep this place hidden. This island is clearly visible from other buzzing tourism destination like St. Martin and St. Bart's, but it is far less travelled. The green mountains jet out from the blue sea and cut through the clouds. It is a hiker's dream and one of the most peaceful places you'll ever visit.
