I also went on a short tour of the Han River that flows through the center of Seoul. Missed the long tour by 5 minutes so we settled for the shorter tour. Check out the gallery.
Got off the boat at Seoul Forrest. This is just a small area with a pond, stream, some trees and wild animals. There were deer running around inside and you could feed them through the fence.
Unfortunately, I didn't have any kimchi in my backpack.
