The top 20 least visited countries in the world

Why so few? Try to get there. United has a monopoly on flights and does know how to price the tickets accordingly.Why you may still want to visit? The diving at the outer atolls is world-class! What else? Do not expect to find cheap accommodation. There is virtually no crime there though, so you might as well sleep on the beach for free.
