Hells Canyon is a 10-mile wide, 80-mile long canyon carved by the Snake River. It contains the deepest gorge in North America at just under 8,000 feet in depth. The canyon itself is part of the Hells Canyon National Recreation Area, which is roughly 652,500 acres and has nearly 900 miles of hiking trails. Some of those trails are within the 218,000 acre Hells Canyon Wilderness.
