If you have nerves of steel, you"d enjoy the precarious, one-of-a-kind photo op that is the Kjeragbolten boulder. Visitors climb up Kjerag, a mountain on the southwest coast of Norway, for the chance to clamber onto the stranded rock and have their daredevil pic snapped for posterity. Indeed, Kjeragbolten is so popular that you might have to wait up to an hour for your turn—plenty of time for second thoughts and jitters.
