| Entrance / Destination | Distance | Drive Time |

I-15 N (Las Vegas → Idaho Falls) → US-20 E (Idaho Falls → West Yellowstone). Alternative: I-15 → I-90 (Butte) → US-89 (Livingston → Gardiner/North Entrance). Similar time.
It's a long haul — but the transition from Mojave to Greater Yellowstone Ecosystem is one of America's great ecological gradients.
