This wild river corridor flows through southeastern Oregon from the Idaho/Oregon state line to Owyhee Reservoir. (It excludes the Rome Valley, which is a ranching and agricultural area.) Explore this National Wild and Scenic River by floating some of its 120 miles through rugged, spectacular canyonlands and ash flows. The river was included in the National Wild and Scenic River System in 1984 because of its outstanding scenic, recreational, geologic, wildlife, and cultural values.
