Photo Gallery Visiting the World's Most Obscure Destinations

For those travel fanatics competing for the title of "world's most traveled person," hard-to-reach places are just boxes to be checked on the ever-growing list of the world's countries and territories. One of them is the tiny Pacific island of Nauru. It's one of the most inaccessible locations for ultra-travelers. Only one airline flies there and visitors have to transit through Australia.

The government of Bhutan tightly controls tourism to its peaceful mountain country.

Located in the southern Pacific Ocean, the Pitcairn Islands have a population of just 48 and are accessible only by boat.

Spaniard Jorge Sanchez is widely considered to be Europe's most traveled man. Here is one of his favorite pictures from a 2009 trip to Russia.
