Park City to West Yellowstone: Ultimate Road Trip Guide

The 370-mile journey from Park City, Utah to West Yellowstone, Montana follows the arc of a prehistoric supervolcano. You'll trace US-89 and US-191 through the remains of the Yellowstone hotspot—a plume that fueled cataclysmic eruptions 16 million years ago, leaving behind the Snake River Plain's vast lava flows and the towering Teton Range.

Expect 6.5 hours of pure driving, but real travelers budget two full days. The route crosses three states, two national forests, and one of the world's most famous national parks. Key waypoints include Ogden's historic 25th Street, the bear-infested roads of the Caribou-Targhee National Forest, and the geothermal wonders of Island Park.

Best stops Park City, UT to West Yellowstone, MT include the Bear River Migratory Bird Refuge at Brigham City, where 200,000 shorebirds roost.
