Sky Tower

Auckland's iconic Sky Tower rises to nearly 1,100 feet and hosts a number of the city's vertigo-inducing activities. There's the Sky Walk on the 53rd floor, where you walk the perimeter of the tower along a four-foot platform. You're suspended by a safety harness, of course, but this is still not for the feint-hearted (or those with vertigo). Also on the 53rd floor is the Sky Jump, where dare devils base jump (attached to a wire, so there's no bouncing up and down like with a bungee) 630 feet into the abyss.

Less adventurous travelers can still enjoy 360-degree panoramas from the Observation Deck on the 60th floor, which has a few glass panels along the floor that cause a rush of excitement when walked over. The Sky Tower is part of so-called Sky City, a convention center with a casino, several restaurants and bars, but it all feels much like a no-descript mall, so there's no need to linger once you've had your fill of panoramas.
