One can simply not visit South Korea without taking a trip to visit the highest building in Seoul. Sitting at the top of Mt. Namsam, the Seoul Tower offers the most phenomenal panoramic views of the city, and has been a symbol of Seoul since it first opened to the public in 1980. Along with the breathtaking views overlooking Seoul on top of the tower, there are four observation decks, a gift shop, two restaurants, snack bars and a Teddy Bear Museum. The best part is riding the cable car up to the mountain and then walking past the most gorgeous views up to the tower.
