With a terrifying 800-foot drop to the fjord below, you have to be a real daredevil to step foot onto Kjeragbolton in western Norway. Either that, or you really love a good photo. Wedged between two cliffs on Kjerag Mountain, this feat is not for the faint of heart. Being Norway, wet weather is frequent, and can make the boulder slippery, increasing your chances of falling to a very scary and untimely death.
Don't forget that it's quite a climb making it up to the boulder. When your legs are shaky from a hike, the last thing you should be doing is a death-defying act. Unusually for Norway, the climb up includes metal chains as safety rails in the most dangerous spots, but this is about as secure as it gets if you're attempting Kjeragbolten.
