This scenic “River of No Return” was formed 35 to 45 million years ago and is the longest free flowing river (425 miles) within one state in the lower 48. The Salmon River’s granite-walled canyons represent the second deepest gorge on the continent, second only to Hells Canyon. Forty-six miles of the Salmon River are classified as recreational and 79 miles are wild and the canyons showcase some of the oldest rocks in Idaho. A wealth of wildlife call the Salmon River Canyon home, including bighorn sheep, bobcat, black bear and beaver, as well as a variety of fish such as cutthroat trout, rainbow trout and bull trout. The white-water rafting opportunities along the Middle Fork Salmon River are unsurpassed in the state.
