Conde Naste just released a slide show of eleven places with glass bottom views — places with steep drop-offs that end in oblivion. Basically, a destination intending to give you a chance to take a leap of faith (will the glass break while I’m on it??). If you want a thrill, then give this link a look.
Of note, while I’ve been to one of these places in only one (CN tower) did step out on the glass. It was a decidedly unpleasant experience and took every bit of willpower I had to do so. Your primitive brain tells you that the next step will be your last!
