Road trip plan
West Yellowstone to Island Park Scenic Drive
Short Route 20 re-entry outing built around West Yellowstone, the park boundary context, and the first Idaho-side continuation into Island Park.
West Yellowstone to Island Park Scenic Drive
This is the Yellowstone west re-entry trip on the site for travelers who want the clearest next step after the park gap without treating Yellowstone itself as a routine through-drive.
Uses these segments
- West Yellowstone and Island Park for the park-edge re-entry and the first Idaho-side continuation
Best anchor towns
- West Yellowstone is the clearest west-side re-entry town after the Yellowstone gap
- Island Park is the calmer continuation town once the route resumes in Idaho
Yellowstone handoff note
The current live build reaches Yellowstone from the east on the Wyoming side, pauses across the park interior, and then resumes west of the park at West Yellowstone. This page is meant for that west re-entry, not as a through-park driving guide.
Best fit
This trip is a good fit for travelers who want to understand where Route 20 picks back up west of Yellowstone, keep the outing scenic and bounded, and then decide whether to continue into Ashton for a fuller Idaho gateway stop.
Keep going
- Use Wyoming for the east approach into Yellowstone and the current pre-park continuity
- Extend the west re-entry with West Yellowstone to Ashton Scenic Drive
- Continue into the first fuller east Idaho weekend with Ashton to Rexburg Route 20 Weekend
- Use Idaho for the fuller west-of-Yellowstone state layer
