Oh, really?
there are so many beautiful places in Korea.
if you are interested in Korean traditional culture, I recommend Gyeongju.
Gyeongju was the capital of Silla for about 1,000 years (Silla is one of the ancient countries in Korea)
so, If you come to Gyeongju, you can enjoy many things.
Especially, Gyeongju is famous for cherry blossom.
