Cody WY to Ketchum ID Road Trip Guide: Scenic Drive Essentials

The drive from Cody, WY to Ketchum, ID spans 350 miles along US-20 and US-26, crossing the Continental Divide at Togwotee Pass (9,658 ft). This route shadows the historic Oregon Trail and offers access to Yellowstone National Park and Grand Teton National Park. Understanding the best stops between these two iconic Western towns transforms a simple transit into a rich exploration of the Rocky Mountain region.

The journey takes roughly 6-7 hours without stops, but with recommended detours and attractions, plan a full day or more. Elevation and weather dramatically influence travel—summer brings wildflowers and clear skies, while winter demands caution and four-wheel drive.

The route transitions from the Bighorn Basin's sagebrush steppe to the towering Absaroka Range. Near Yellowstone's east entrance, geothermal features like mud pots and hot springs appear. Grand Teton National Park's jagged peaks rise abruptly from the valley floor, offering iconic photo ops.

• Yellowstone Lake: A short detour to Lake Butte Overlook provides a panoramic view of the largest high-altitude lake in North America.
• Teton Science Schools: In Jackson, educational programs about local ecology are available for families.
• Local commerce in Dubois includes the National Bighorn Sheep Center and a few artisan shops selling Western gear.

UNESCO World Heritage Sites: Yellowstone National Park (designated 1978) is on the route—plan extra time to explore its thermal basins and wildlife. Grand Teton National Park is not UNESCO-listed but is a designated Biosphere Reserve.

Ketchum sits in the Wood River Valley, surrounded by the Sawtooth National Recreation Area. The area's history as a mining and ranching hub is preserved in the Ketchum Historical Museum.

The primary highways are US-20 west from Cody, which becomes US-26 and then US-89 near Jackson. The roads are well-paved but can be narrow and winding in mountain passes. Cellular coverage is sparse, especially between Dubois and Jackson; downloading offline maps is advisable.

• Fuel stations are concentrated in Cody, Dubois, Jackson, and Ketchum. Intervals of 80 miles mean you should fill up when below half a tank.
• Most services (restaurants, lodging) are seasonal; check ahead for winter closures.
• Road conditions: Wyoming 511 and Idaho 511 provide real-time updates. Togwotee Pass can close due to snow.

The cost of fuel varies; budgeting $50-70 for a typical sedan is reasonable. Food expenses average $30-50 per person per day if eating out. Accommodation in Jackson and Ketchum is pricey, while Dubois offers budget motels.

Wildlife crossings are common—elk, moose, and bison wander onto roads at dawn and dusk. The speed limit on US-20 is 65 mph but slows in construction zones. Mountain passes require reduced speed: Togwotee Pass has sharp curves and potential ice patches even in May.

• Fatigue management: Plan to stop every 2 hours. Recommended rest areas include the Togwotee Pass scenic overlook and the Jackson Visitor Center.
• Family suitability: The route is family-friendly with educational stops like the National Museum of Wildlife Art in Jackson. Kid-friendly dining options exist in all towns.
• Pet-friendly framework: Most rest stops have pet areas, and many hotels in Dubois and Jackson allow dogs. Keep pets leashed due to wildlife.

Hidden off-route spots: Blackrock Ranger Station has a small interpretive trail leading to a historic cabin. In Idaho, the Craters of the Moon National Monument is a 50-mile detour south from Carey; its volcanic landscapes are otherworldly.

Climatic conditions: Summer temperatures range from 70°F days to 40°F nights. Afternoon thunderstorms are common. Winter sees heavy snow and subzero temperatures; check forecasts before departing.
