Img 20190126 084005 Zion National Park in Utah.Perhaps the scariest hike in America, Angels Landing in Zion National Park in southern Utah is 2.5 miles and 1,500 feet of rising, fear-inducing elevation, even for the most experienced hikers. The last half-mile is particularly notorious, with sharp drop-offs, narrow paths and steel chains that visitors cling to for dear life - after all, at least 15 people have reportedly died from these heights.
