After taking a 4.5 hour bus ride to Mokpo from Seoul, then another 2.5 hour ferry ride, I’ve finally arrived at this beautiful little island of Hongdo in the Yellow Sea, way down southwest of South Korea.
The island only has a population of 710.

On Hongdo, meaning "Red Island" due to the red coloring found on many of the rocky outcroppings, there are about 270 varieties of evergreens and 170 species of animals. The government wished to preserve the natural state of the island so Hongdo was designated as a Natural Preserve Area in 1965, and became part of Dadohae Marine National Park in 1981. Because the entire island of Hongdo is declared a Natural Monument, no one is allowed to enter areas other than the villages and designated tourist areas.
