McCall to Riverton Road Trip: Scenic Drive Through Idaho and Wyoming

Did you know the route from McCall to Riverton roughly follows the path of the historic Oregon Trail, which saw over 400,000 emigrants pass through in the 19th century? Today, this 542-mile journey from McCall, Idaho to Riverton, Wyoming takes you through some of the most rugged and stunning terrain in the American West. The drive typically takes 8-9 hours without stops, but the real magic lies in the detours. Planning your stops is essential: learn how to find the best stops and hidden gems between cities to maximize your adventure.

The route primarily follows US-95 south from McCall, then east on ID-75 through the Sawtooth Scenic Byway, connecting to US-20, US-26, and finally US-287 into Wyoming. While the main highways are well-maintained, many side roads are gravel, especially in the national forests. Cell service is spotty, especially between Stanley and Arco, so download maps offline. The best time to drive is between late May and early October, when snow is less likely at higher elevations.

Gas stations are sparse, particularly in the stretch between Stanley and Arco (about 120 miles with no services). Fill up in McCall, then again in Stanley, Arco, and Jackson. Gas prices in McCall tend to be $0.20-0.50 higher than the national average, but they drop slightly in Arco and Jackson. Plan for fuel costs around $60-80 for the trip.
