HELLS CANYON — AMERICA’S DEEPEST RIVER GORGE

Snake River Adventures, LLC

Hells Canyon is recognized as the deepest river gorge in North America, reaching approximately 7,993 feet at its deepest point from the Snake River to the surrounding peaks.

That tremendous change in elevation gives Hells Canyon a scale that can be difficult to appreciate from photographs alone. From river level, mountains, ridges and canyon walls rise thousands of feet overhead while the Snake River winds through the rugged landscape below.
Unlike a canyon defined by a single sheer rim, Hells Canyon is a vast landscape made up of mountains, ridges, side canyons and river corridors. The result is a constantly changing view as you travel upriver.

Millions of years of volcanic activity, uplift and erosion helped create the dramatic landscape visitors experience today.
