Suwon Hwaseong, a UNESCO World Heritage site, is a course that requires lung-walking along the fortress walls. It is essential to use lockers near Suwon Station or Haenggung Palace to enjoy the view lightly.
Suwon Station has the most lockers, and there are small storage facilities near the Haenggung Palace Information Center. It's good to store bags before touring Haenggung-dong (Haengnidan-gil).
