Gardiner to Buffalo: Ultimate Road Trip Guide

The route from Gardiner, Montana to Buffalo, Wyoming follows US-89 south through Yellowstone National Park, crossing the Continental Divide at Craig Pass (8,262 ft) before descending into the Bighorn Basin. This 300-mile drive passes through two national parks and the Shoshone National Forest, offering dramatic geological contrasts—from geothermal basins to granitic peaks.

The drive traverses the Beartooth Highway's southern edge, passes Yellowstone Lake, and crosses the Bighorn Mountains via US-16. Notable for its wildlife crossings and high-altitude passes, this route offers a unique mix of volcanic and alpine landscapes.

Road quality varies: US-89 is well-maintained but narrow in Yellowstone, while US-16 over Powder River Pass offers switchbacks and occasional gravel patches. Speed limits are 45 mph in park areas, 70 mph on open highway. Expect long stretches without services; fuel up in Gardiner, Silver Gate, or Cody before the 150-mile gap to Greybull.

Fuel and Economy Notes

• Fuel prices tend to be 10-15% higher in park gateway towns; prices drop by about 5% in larger towns like Cody.
• Consider a fuel-efficient vehicle: the altitude gains (up to 8,524 ft) can cut fuel economy by 10%.
• Cash not always accepted at remote pumps; carry credit cards.

Wildlife collisions are common on this route, particularly at dawn and dusk. Watch for bison, elk, and deer. In winter, chain controls are frequent on the Beartooth Highway; check weather forecasts and carry tire chains.

For families, the Cody Dinosaur Museum and the Buffalo Bill Center offer engaging exhibits. The route includes kid-friendly hikes like the Mystic Falls Trail (moderate, 2 miles round trip).

Service stations are sparse; plan rest breaks at scenic pullouts like the Sylvan Pass Overlook or the Greybull River Rest Area. Fatigue management tips: take a break every 2 hours, alternate drivers, and stay aware of high-altitude fatigue—symptoms include drowsiness and difficulty concentrating.

Yellowstone, the world's first national park, claims half of the world's active geysers, including Old Faithful—a must-see. At the park's south entrance, Grand Teton National Park's jagged peaks define the horizon. The Bighorn Canyon National Recreation Area, with its limestone cliffs, rivals the Yellowstone's drama.

This route passes through the rich history of the American West—from the ghost town of Kirwin to the frontier town of Cody, home of the Buffalo Bill Center of the West.

Local commerce thrives in gateway towns: in Gardiner, visit the Yellowstone Gateway Museum; in Cody, wander the historic downtown with its western boutiques. For a taste of local flavor, stop at Red Oak Bar & Grill in Buffalo—a favorite among ranchers.

Indigenous heritage is significant: the route crosses the Crow Reservation, where you can experience cultural tours and events.
