During my time in Korea, I've been lucky enough to have a fair number of visitors. My best friend is currently visiting from back home in the U.S., and as I've been pulling her around Seoul to the spots I deem the most interesting and picturesque, I realized that I've got this tour guide thing down to a science. So whether you're new to Korea yourself or you're expecting visitors during your time here, let this be a guide for the spots you should definitely see.
