Why drive this stretch
Drive this stretch when you want the clearest way to turn the Yellowstone west re-entry into a usable route section instead of a simple endpoint note. West Yellowstone gives the route a visible re-entry town, Island Park keeps the corridor moving in a calmer landscape, and Ashton gives the site its first fuller Idaho gateway town west of the park.
