Trail Conditions
No reports yet
The Salmon River Backcountry is one of America's most extreme and committing off-road drives. Precipitous dirt roads cling to canyon walls thousands of feet above the river, with no guardrails, no cell service, and no turning back for miles at a time. This is the real deal, remote, exposed, and utterly spectacular.
Fun Facts
The Salmon River Canyon is deeper than the Grand Canyon in some places.
Lewis and Clark declared the Salmon River impassable, naming it 'The River of No Return.'
The Frank Church River of No Return Wilderness is the largest contiguous wilderness in the lower 48.
