There are spectacular views of Seoul from the top of Namsan Park, and compared to some big cities you can actually see through the haze.
I took a cable car to the top, which was a little too squashed to be enjoyable. You can pay extra to go up Namsan tower but I figured another few hundred metres of height wasn’t going to make much of a difference.
Note: click the photo to see a lot of extra detail. I ran out of fingers when counting the apartment blocks in the distance.
