About Us The Loess Hills landform is an Iowa treasure that spans more than 1,080 square miles along the eastern edge of the Missouri River flood plain. This unique feature is up to 15 miles wide and 220 miles long. Bridging rural and metropolitan areas, the hills have something for everyone.
The Loess Hills National Scenic Byway began in 1989 as a grassroots effort by dedicated citizens in cooperation with Golden Hills Resource RC&D and the Western Iowa Tourism Region. The Byway became an Iowa Scenic Byway on July 8, 1998 and on June 15, 2000 received the National Scenic Byway designation.
