There’s quite a bit to see and do in the 63 Building. We decided to go for the “big 3” and pick the aquarium, wax museum, and sky art gallery. Admission for that was 30,000 won (~$27.08 CAD). Of course there were other options, but we decided it was worth it to check out those 3 attractions. I enjoyed the aquarium, the wax museum was sort of interesting, and the sky art gallery had a fantastic view of Seoul. You definitely can’t go to the 63 building without going up to the sky art gallery! It’s a must!
