Fuel up in Driggs (last cheap gas for a while). The next reliable stations are in Idaho Falls (55 mi), then Arco (85 mi), and again in Boise (190 mi). Arco to Boise is the longest stretch without major services, so plan accordingly. Gas prices fluctuate, but expect Idaho to be cheaper than Oregon.

Road quality is generally excellent: US-20 is a well-maintained two-lane highway through farmland and lava fields. US-26 near the Oregon border narrows and becomes winding – take caution at dusk. I-84 east of Boise is divided freeway with rest areas every 30 miles.

• Driggs altitude: 6,200 ft. Mosier altitude: 160 ft. That is a massive descent.
• Cell service: Spotty between Arco and Mountain Home. Download offline maps.
• Weather: Windy along I-84, especially in the Columbia Gorge. Gusts can exceed 40 mph.

For electric vehicles, charging stations are limited in Idaho. There are Superchargers in Idaho Falls and Boise, but none in Arco. A full charge from Driggs may require an extended stop in Idaho Falls. Always carry a backup plan.

The most efficient route is US-20 west to I-84 west. An alternate is US-26 through the Sawtooth Scenic Byway, adding 2 hours but rewarding with mountain vistas. However, winter conditions often force closure of this route.

Safety considerations include winter conditions from November to April – snow tires or chains may be required over mountain passes. In summer, afternoon thunderstorms can cause sudden downpours. Wildlife, especially deer and elk, are common at dawn and dusk. Deer crossings are frequent on US-20 near Carey, Idaho.

Fatigue management is crucial on this long drive. Recommended rest zones include the Idaho Falls rest area (milepost 119 on I-15) and the Fort Hall Rest Area (US-20 near Blackfoot). In Boise, the Tamarack Resort exit has a large rest area.

• Best for families: Craters of the Moon Jr. Ranger program, Shoshone Falls park, and the Discovery Center in Idaho Falls.
• Pet-friendly: Most rest areas allow leashed pets; many picnic areas are grassy. In Boise, the Ann Morrison Park is a great off-leash spot.
• Hidden off-route spot: The Market Lake Wildlife Management Area near Roberts, Idaho – a serene marsh with birdwatching.

Restaurants along the route: In Arco, the Pickle's Place serves classic American breakfast and lunch. In Mountain Home, the German restaurant Alt Haus decor is a quirky stop. In Boise, the Bardenay distillery offers lunch with a view of the river. Mosier's own The Riv is a popular food cart pod with live music.

For a unique overnight option, consider staying at The Lava Flow Campground near Craters of the Moon (no reservations) or a historic hotel in Boise's downtown. If you are not in a rush, break the drive at one of these spots to explore further.

Natural landscapes along this drive are vast and varied. Start with the Teton Valley farms, then descend into the Snake River Plain. At Arco, you encounter the Craters of the Moon National Monument, a surreal volcanic landscape with lava tubes and cinder cones worth a 1-2 hour detour. No entrance fee for the loop road.

Near Bliss, Idaho, the Snake River cuts a deep canyon visible from the highway. Further west, the Shoshone Falls in Twin Falls (15 miles south) is higher than Niagara – a spectacular stop if time allows.

• Craters of the Moon: Open year-round, but summer is best. Winter snow may limit access.
