N Seoul Tower
Built atop a hill, this is the highest point in the city and a fantastic place from where to get your bearings upon arrival. The 236m tower (which measures just under 500m above sea level) grants breathtaking views of the city in its most magnificent glory. Hike up on foot if you feel game (otherwise take the cable car), as this gives you several fantastic viewpoints along the way. Head here at 5.30pm and you’ll see the city at dusk and as the bright lights come on, but do pick a clear evening to come up or you’ll risk seeing nothing much at all.
