If I had to pick just one area for some history and stuff, I’d probably stump for Gyeongju. As well as one of Korea’s prettiest sights, the museum was a stand out. Nearby Yangdong is yet another hanuk- traditional village- but quieter than those in the cities.
And when you can’t do any more temples, Juwungsan mountain has some of the nicest, quietest hiking in the country.
