Straddling the Idaho-Oregon border is Hells Canyon, North America’s deepest river gorge. Surpassing even the Grand Canyon in depth, this over 650,000-acre natural wonder, designated as the Hells Canyon National Recreation Area in 1975, offers breathtaking vistas and diverse landscapes. Carved by the Snake River, the canyon reaches a maximum depth of nearly 8,000 feet, making it almost 2,000 feet deeper than the Grand Canyon.
