The Sky Tower in Auckland, New Zealand, is an iconic landmark that stands tall at 328 meters, making it the tallest structure in the Southern Hemisphere. You can enjoy panoramic views of the city and beyond from its observation decks. The tower features a glass floor for those brave enough to look straight down, and thrill-seekers can even try the SkyJump, a controlled base jump from the top. With restaurants and cafes on-site, it's a great spot to grab a bite while soaking in the scenery. I recommend going up there on a clear day to have the best view.
