Jumping from a spring destination to an autumn one, we have the gorgeous foliage of Nami Island. This half-moon-shaped island wasn’t always an island; it became isolated following the establishment of the Cheongpyeong Dam in 1944. Although it’s possible to visit Nami Island year round, the beautiful trees and forest trails look their absolute best when the colors change in autumn. The island is an especially popular domestic destination due to its use as a filming location for popular TV show Winter Sonata. Beyond that, Nami Island is designed with kids in mind, with a miniature train and playgrounds, plus a zipline for those who are still kids at heart.
