Seoul walking tours
While in Seoul, Korea, in August 2014, I went on 10 or so free walking tours, each led by an English-speaking volunteer guide. Each tour lasted two to three hours.
Reservations must be made at least three days ahead of time. I made reservations two to three weeks in advance by going to Visit Seoul: The Official Travel Guide to Seoul (www.visitseoul.net). After clicking “English,” select “See & Do,” then click on “Must See & Do,” then “City Walking Tours,” then “Course Introduction.”
