Why drive this stretch
Drive this stretch when you want the cleanest west-side Route 20 reset after Yellowstone. West Yellowstone gives the corridor a recognizable re-entry town, and Island Park keeps the route moving again in a calmer, more open landscape without asking you to treat the national park interior as one more normal highway segment.
