Climb The Tallest Mountain In The World In 30 Mins

Mount Everest gets all the credit, but Hawaii’s Mauna Kea (an idle volcano that’s been around for, you know, a million years) is technically the world’s tallest mountain. Technically. While it stands 13,800ft above sea level, more than two thirds of the hill is actually submerged underwater, which brings the total height to 33,136ft.
