The corridor winds along two wild and scenic rivers, the Middle Fork of the Clearwater River and the Lochsa River. Scenery is beautiful through the corridor, ranging from dense forests to shrubfields created by wildfires in the early 1900s. Canyon walls are steep, and rock outcroppings are impressive.
Two main routes into the corridor make it possible to tour the area in a loop, with little backtracking. Road 247 from the small community of Headquarters is a paved, mostly winding road. Road 250 is paved for several miles from its junction with State Highway 11 just south of the town of Pierce.
The corridor is made up of two main travel routes: State Highway 6 from Potlatch east and north to the St. Joe Divide, and State Highway 8 from Deary to Elk River. While forested, the area borders the rolling hills of the rich farmland known as the Palouse prairie. In the Palouse corridor itself are stands of old-growth cedar, grand fir and western white pine.
