I visited Lotte World Tower & Sky Bridge (Seoul, South Korea). Oct. 2022

During my time in Seoul, South Korea, I visited the tallest building there which is called Lotte World Tower. It is an enormous building! It sticks out and you can see it from most places in Seoul. It is 123 floors! It features it's own amusement park, HUGE mall, a decently-sized aquarium, an insane amount of shops, eateries, and more all within. Then, on top of it, you can do paid tours to visit the Tower itself and even do a walk, between both towers on a steel platform. It's a must-do if you want something incredible and unforgettable while you are in Seoul.
I think everything that I did was around $120 USD (including printed 5x8 pictures at the end).
See what it was like from my view during this adventure.
Lotte World by itself is worth the visit, and this was just the frosting of the cake.
