Korea is one of my favorite travel destinations because of its fascinating culture, complicated history, and sheer abundance of things to do.I've traveled to both North Korea and South Korea. Separated by the 4km wide Demilitarized Zone (DMZ), the nations seem worlds apart even though they share the same language, costumes, and traditional music. Sadly, today, both sides are technically still at war.Beneath the gloss of K-pop, K-beauty, and K-consumer goods is a stoic industrialism that propelled South Korea's economic growth from poverty to power in just two generations. There is as much to discover in Koreans' changing worldviews and values as there is in the landscapes, architecture, and products - especially if you travel beyond Seoul.
