We had the chance to visit Seoul Skyline, the third highest observation deck in the world, which opened a few days after our arrival to Seoul. The observatory is located on the upper floors (117-123F) and it offers a wonderful view of the city especially at night. 

The deck has a transparent glass FLOOR you can walk on and see what's going under your feet!! isn't that amazing?

It is recommanded to go there on clear days (not foggy) to enjoy the best views of the city.
