Hells Canyon Wilderness

Hells Canyon Wilderness is a subset of the Hells Canyon National Recreation Area (HCNRA), which straddles the border of northeastern Oregon and western Idaho. Split into two distinct halves by the Wild & Scenic Snake River, approximately one-third of HCNRA comprises the Hells Canyon Wilderness. A small portion of the Wilderness in Oregon is managed by the BLM. The Idaho side of the Wilderness is smaller than the Oregon side and encompasses the Seven Devils mountain range. On the Idaho side, the Wilderness stretches south from Pittsburg Landing for approximately 31 miles along the Snake River. In the summer, the temperature at the river often reaches 110 degrees F. After May, hiking in the canyon is very difficult due to heat.
