It's SO Romantic - Must See this a Second Time!
My boyfriend and I thought the view was breathtaking, fun and educational at the same time. From any point, you can walk around, and see not only Seoul, but also know exactly how far away you are from all the major cities in the world. Plus, each window gives you a historical overview of the area.
Tips: You don't need to get "sucked into" taking the cable car at the peak of the Tower. Just go to Myeong-dong station (very close) and take the cable car UP. We didn't see the point of taking it down from the mountain. Also, take a seperate day to visit the "Family Spots" and "Romantic Spots", these can't all be covered in one visit.
And most important, BRING COMFY SHOES! It's very steep even for 200 meters to the actual entrance:)
