This scenic route winds through the Snake River Plain’s ancient lava flows and high desert, showcasing some of Idaho’s most dramatic geological features. The byway passes basalt formations, sagebrush flats, and distant mountain views while connecting several small towns and recreation areas. Traffic is light except during summer Yellowstone season, making it ideal for unhurried exploration.
The route is entirely paved but services are sparse between towns — fuel up in Arco or Ashton. Winter driving requires caution due to wind and occasional snow, while summer offers the best weather for side trips to nearby wilderness areas.
