Hell’s Canyon plunges 7,993 feet from the Seven Devils Mountains to the Snake River, making it North America’s deepest river gorge — deeper than the Grand Canyon. The canyon stretches 125 miles along the Idaho-Oregon border, accessible via scenic drives, hiking trails, and river access points. Hat Point Overlook on the Oregon side provides the classic rim-to-river view, while Hells Canyon Dam marks the southern boundary.
Access varies dramatically by season and route. The Idaho side via Forest Road 517 requires high-clearance vehicles and closes with snow. River access points like Pittsburg Landing involve steep, winding roads unsuitable for large RVs. Spring through fall offers the best conditions, though summer brings extreme heat in the canyon bottom. Cell service is virtually nonexistent in the depths.
