Driggs to La Grande Road Trip: Scenic Drive through Idaho and Oregon

The 275-mile journey from Driggs, Idaho (elevation 6,110 ft) to La Grande, Oregon (elevation 2,780 ft) drops over 3,300 feet, crossing the Continental Divide near Teton Pass. This route follows US-26 west through the Caribou-Targhee National Forest and Idaho Falls, then merges onto I-84 near Burley. A peculiar fact: the Teton Pass summit at 8,431 ft has a 10% grade westbound – the steepest sustained grade on a US highway in the region. Average drive time is 5 hours without stops, but plan for 7-8 hours to enjoy key detours.

Fuel availability is decent but spaced: fill up in Driggs (last cheap gas before Teton Pass), Idaho Falls, Burley, and then La Grande. Expect fuel costs around $3.80/gal for regular in Idaho, slightly higher in Oregon (full-service only). Restrooms are at most gas stations and rest areas. The route includes two major mountain passes: Teton Pass (8,431 ft) and Monida Pass (6,870 ft) on I-15 south of Dubois.

• Key exits: Exit 119 (Idaho Falls), Exit 53 (Twin Falls), Exit 261 (La Grande). Watch for livestock on US-26 near Swan Valley.
• Cell service: Good on I-84 and I-15; spotty on US-26 from Driggs to Idaho Falls, especially in canyons. Download offline maps.

The best time to drive is June through September; winter requires chains or snow tires over Teton Pass. Spring (April-May) brings melting snow and occasional road closures. Autumn (October) offers mild temperatures and vibrant foliage in the Oregon side.

• Check road conditions at 511 (Idaho) and TripCheck (Oregon).
• Avoid driving at night due to wildlife (deer, elk) on US-26 and I-84 near Meacham.

Road quality is good overall: US-26 is a two-lane highway with occasional passing lanes; I-84 is a four-lane interstate. Winter conditions require caution on Teton Pass and Monida Pass. Watch for rockslides on US-26 near Swan Valley.

• Emergency services: Hospitals in Idaho Falls (Eastern Idaho Regional Medical Center) and La Grande (Grande Ronde Hospital). Call 911 and give mile marker.
• Pet-friendly: Most rest areas allow leashed pets; the Idaho Falls Dog Park (off Fairgrounds Road) is a good stretch break.

Family-friendly stops: The Museum of Idaho (Idaho Falls) has interactive exhibits. At Burley, the Hillcrest Aquatic Center is a summer cool-off. For kids, the Oregon Trail Interpretive Center offers wagon rides and gold panning.

• Rest zones: Rest areas at mile 105 (US-26 near Idaho Falls) and mile 175 (I-84 near Burley) have restrooms, picnic tables, and vending machines.
• Fatigue tips: Pull over at any rest area or gas station every 2 hours; drink coffee from local roasters like City Brew in Idaho Falls.

• Hidden off-route: The town of Shoshone (exit 141 on I-84) has the Shoshone Ice Caves, a 1,000-ft lava tube open May-September.
• Another gem: The Minidoka National Historic Site in Jerome (exit 173) preserves the legacy of a Japanese American internment camp.

The first 30 minutes from Driggs take you over Teton Pass with sweeping views of the Grand Teton to the east. Descending into Pierre's Hole, you'll pass through the town of Victor (pop. 2,000), a hub for skiers and mountain bikers. Stop at the Teton Valley History Museum in Driggs for local lore.

• Natural landmarks: Palisades Reservoir (mile 55 on US-26), a prime spot for fishing and boating. The Snake River parallels the highway near Idaho Falls.
• Hidden gem: The Craters of the Moon National Monument is a 40-minute detour from I-15 near Arco; reachable via US-20/26 west of Idaho Falls.

After Idaho Falls, the landscape shifts to agricultural plains and sagebrush. Near Burley, the Snake River Canyon offers a dramatic gorge. Just before La Grande, the route enters the Wallowa-Whitman National Forest, with pine forests and the Grande Ronde River Valley.

• Local commerce: Visit the Idaho Falls Farmers Market (Saturdays, April-October) for local produce and crafts. In La Grande, the Oregon Trail Interpretive Center at Flagstaff Hill tells the story of westward migration.
• UNESCO sites: None directly on route; the nearest is Yellowstone National Park (2.5 hours north of Driggs).
