I made the 200-mile trip from Seoul (where I live) to Busan—there and back!
I have almost made a straight line through South Korea in my travels so far. I went as far North as you can go and then to Busan, which is very far South East.
I took the train to Busan, which took six hours. Once I got there, I took the subway and buses to get around the city, which was pretty easy.
I went to Haedong Yonggungsa Temple, a beautiful Buddhist temple. It was much bigger than I expected.
Photobooths are super popular in South Korea. I have made quite a few stops with friends!
