Granite Creek Rapids is the deepest part of Hells Canyon, reaching 8,000 feet below Idaho's He Devil Peak. That is more than three times the height of the Empire State Building.
Hells Canyon National Recreation Area covers more than 650,000 acres, where nearly 900 miles of trails are available for people to hike, mountain bike or go horseback riding.
According to the U.S. Forest Service, the Hells Canyon National Recreation Area is part of three National Forests including the Payette, Wallowa-Whitman and the Nez Perce.
The Hells Canyon All-American Road is a 225-mile road that was made a National Forest Service Scenic Byway in 1992 and has since been named a State Scenic Byway. The most scenic part is said to be between the towns of Joseph and Halfway.
The Snake River and nearby Salmon River are home to trout, bass, steelhead, sturgeon and salmon. During the summer, river levels are more manageable and many fishing tours are offered through local outfitters.
The area is also home to dozens of bird species, deer, elk, bighorn sheep, mountain lions, mountain goats, black bears and various reptiles and amphibians. The 10-mile span of the canyon includes an extremely diverse range of habitat and wildlife due to the enormous variety in elevation change within the area.
