Namsan is a 262 meter mountain in Seoul, with a 237 meter high communication tower called N Seoul Tower on top of it. So when you find yourself on one of the tower’s observation decks you’ll almost be 500 meters up in the air. And naturally you'll have an awesome night view of the grand city of Seoul from there.
Getting there can be quite nerve-racking in an overcrowded cable car that was built in 1962. For six minutes (three up and three down) we were smashed into one of the cable car’s windows by a mass of people, which was highly uncomfortable, but at least the view was good.
