Rapid City to Driggs Road Trip Guide: Landscapes, Logistics & Hidden Gems

Rapid City sits at the eastern edge of the Black Hills, where the rolling plains meet ancient granite peaks. Driggs, Idaho, lies across the Wyoming border, tucked under the west flank of the Teton Range—a valley of hayfields and quiet ski slopes. The direct distance is 536 miles, but the most compelling route stretches over 800 miles, snaking through Badlands National Park, the Bighorn Mountains, Yellowstone National Park, and the Snake River Plain.

A little-known fact: the stretch of US-16 from Buffalo to Cody follows an old Native American trail later used by miners, and its highest point—Powder River Pass at 9,666 feet—is the second-highest paved pass in Wyoming. That high-altitude crossing means snow can linger into June, a reality that shapes every traveler's planning.

Driving time without stops clocks around 13 hours, but the landscape demands doubling that. Yellowstone alone can absorb two days. The question how long to drive Rapid City, SD to Driggs, ID is really about how many wonders you choose to pause for—and the answer is never less than a full three-day escape.

Fuel economy matters in these wide-open spaces. Gas stations cluster in towns like Buffalo, Greybull, and Cody, but the stretch between Cody and West Yellowstone has only the Moran Junction station, nearly 100 miles apart. The average unleaded price in Wyoming hovers around $3.80/gallon, while Idaho's Teton Valley often runs 10–20 cents higher.

Using a tool like how to find the best stops and hidden gems between cities helps pinpoint reliable fuel points and unexpected pull-offs. On this route, the 70-mile gap between Greybull and Cody is a critical range marker—fill up in Greybull.

Is it worth driving Rapid City, SD to Driggs, ID? For scenery, yes. For efficiency, no—flights to Jackson Hole are faster but costlier. The driving route rewards those who savor high plains, volcanic plateaus, and mountain ranges in sequence.

The route passes near two UNESCO World Heritage sites: Yellowstone National Park (designated 1978) and the newly inscribed Hopewell Ceremonial Earthworks (2023) are detours, but the core drive skirts the southern boundary of the park. The Bighorn Canyon National Recreation Area, though not UNESCO, offers comparable geological drama—a 1,200-foot-deep canyon carved by the Bighorn River.

Local commerce along the way tells a story of ranching and tourism. In Buffalo, the historic Occidental Hotel serves bison burgers and craft beer in a saloon that once hosted Teddy Roosevelt. In Cody, the Irma Hotel's prime rib is a rite of passage. West Yellowstone features elk tenderloin and huckleberry milkshakes at Serpentine Spirits. Driggs's culinary scene is small but earnest: the Trap Bar & Grill serves Idaho finger steaks, and the local co-op offers farm-to-table provisions.

• Best stops Rapid City, SD to Driggs, ID: Devil's Tower (detour north), Bighorn Canyon (south of Lovell), Mesa Falls Scenic Byway (near Ashton).
• Hidden off-route spots: The ghost town of Kirwin, Wyoming, accessible via unpaved road from Meeteetse; the Teton Science Schools' Murie Ranch in Moose (close to Driggs).
• Things to do between Rapid City, SD and Driggs, ID: Hike the Leigh Lake Trail in Grand Teton, float the Snake River, or tour the Buffalo Bill Center of the West in Cody.

Altitude sickness is a real concern on this route. Powder River Pass sits above 9,600 feet; many drivers feel dizzy or short of breath. Acclimate by spending a night in Buffalo (elevation 4,600 feet) before ascending. Keep water and snacks handy—dehydration worsens symptoms.

Wildlife crossing the road is common at dawn and dusk. Bighorn sheep, elk, and even moose appear on US-16 and US-20. Speed limits are 65–70 mph, but reduce to 50 mph near forested edges. Wyoming has a high rate of fatal crashes involving animals; 40% of all vehicle accidents involve wildlife.

• Family and child suitability: Buffalo's Jim Gatchell Memorial Museum and Cody's rodeo (June–August) engage kids. Yellowstone's junior ranger program is free and educational.
• Pet-friendly framework: Most motels in Buffalo and Cody accept pets for a $20–$40 fee. Yellowstone's boardwalks allow leashed dogs, but backcountry and thermal areas are off-limits. Driggs has several pet-friendly vacation rentals.
• Fatigue management & rest zones: Rest areas exist at I-90 mile markers 51 (westbound) and 193. The Buffalo Rest Area on US-16 has picnic tables. Plan to stop every 2 hours for 15 minutes.
• Infrastructure safety & road quality: US-16 is well-maintained but narrow and curvy near the pass. I-90 is excellent. US-20 from West Yellowstone to Ashton is straight and fast—watch for crosswinds.
