I visited South Korea for the first time at a few months ago and now I got the pictures unwrapped. I think it is a beautiful city and country!
As the last day activity I took a hike late at night up to the N-tower through the woods. I highly recommend it if you are visiting the city! It was beautiful and calm. Also a little dark from time to time.
I found a very interesting path coming down the hill that look super nice when it is dark.
