He Devil and She Devil are two peaks at about 9400ft elevation in Idaho that are considered co-highpoints of the Seven Devils Mountains unless a modern survey can determine that one is higher by a few feet. Flanked on either side by two major river canyons, including one of the deepest in the country, one of these peaks is one of Idaho's 3 ultraprominent summits. Because He and She Devil are separated by less than half a mile of class 3-4 terrain and only 600 vertical feet, peakbaggers interested in this statistic often visit both in a single day.
