- West Yellowstone: Multiple gas stations, grocery stores (Albertsons), restaurants, and gear shops
- Inside Yellowstone: Gas at Canyon Village, Old Faithful, Fishing Bridge, Grant Village, and Mammoth

Driving Tips & Timing Strategies
- Leave by 7 AM in summer to avoid the entrance line — you can be at Old Faithful before 9 AM
- Keep your park pass visible on the dashboard for faster re-entry on multi-day visits
- Download offline maps — cell service is spotty to nonexistent inside Yellowstone
- Pack snacks, water, and a full tank of gas. Services inside the park are spread out.
- Bring binoculars — you'll spot wildlife from the car on the Madison River road
- Drive slowly and watch for bison on the road. They have the right-of-way. Always.
- Return to Island Park by 4–5 PM to avoid late-day traffic backing up at the entrance
The Golden Hours
The best strategy: enter the park early (by 7–8 AM), do your major attractions in the morning, and head back to Island Park by mid-afternoon. You'll avoid the worst traffic and see the best wildlife.
