Island Park
On Route 20
Island Park is the Idaho-side continuation town that gives Route 20 a clear west re-entry beyond West Yellowstone. It is the place to slow the post-park rhythm down before the route opens up again toward Ashton.
Use it when you want a quieter Idaho-side pause instead of trying to make the Yellowstone boundary feel like a normal highway segment.
What it pairs with
Island Park pairs best with West Yellowstone, Ashton, the West Yellowstone and Island Park segment, the West Yellowstone, Island Park, and Ashton segment, the West Yellowstone to Island Park Scenic Drive, the West Yellowstone to Ashton Scenic Drive, and the Yellowstone Approach store when you want the first practical Idaho-connected stretch west of Yellowstone.
