Idaho's Lower Salmon River

The Lower Salmon River rafting trip begins about 50 miles upstream from the mouth of the Salmon River, continues through the mouth of the Salmon River, and then downstream about 20 miles on the Snake River in the lower end of Hells Canyon on the Idaho/Oregon border  to road's end about 25 miles upstream from Lewiston, Idaho. Though not designated as wilderness, it is back country. There are only a few miles of primitive road along this 70-mile section of river. Terrain consists of rugged grassy slopes rising 3000 feet above the river with scattered strands of timber and basalt rimrock, alternating with miles-long granite canyons. It is low elevation as well as the lower end of the Salmon River; the trips starts at only  little over a thousand feet.
