8. Hiking
As Korea is mountainous, it should come as no surprise that hiking is the national pastime.
Even the most crowded of cities have mountains that offer a relative haven from the kinetic madness of the streets below.
Koreans are at their best on the mountain. They smile and greet you and will often insist on sharing their food and drink. Make sure to stop at a mountain hut restaurant for pajeon (fritter) and dong dong ju (rice wine).
