Located in Lemhi County, this outing starts in Salmon, Idaho and goes south on US Highway 93 to Elk Bend. This stretch of road is also referred to as the Salmon River Scenic Byway, which is one of the most popular byways in the Northern Rockies. The route rolls through fertile agriculture land next to the Salmon River, with a few short sections of steep grades. Expect a lot of curves, and the shoulder width on the highway is 1 - 2 feet. Also, keep in mind that there are limited services along the ride, so be well equipped with food, water, and supplies.
