Best Driving Roads in Idaho
Idaho's selected drives pair mountain passes, river corridors and forest routes. Several are long point-to-point itineraries, so check fuel and road conditions before leaving the main towns.
These 8 editorial picks come from the RevRoutes Explore catalog. Each orange line is the exact saved itinerary, and its listed mileage follows that route rather than the full length of a named highway or byway. The list is a starting point for choosing a drive, not a live road-conditions report.
Exact catalog lines. Every orange route below is a real RevRoutes itinerary—not a pin, shortcut or newly calculated alternative.

Exact saved Explore itinerary. The displayed distance follows this line; the full named road may continue beyond the selected start or finish.
Old Spiral Highway climbs above the Lewiston area with a very different character from the modern highway approach. Its close succession of bends makes this a focused drive rather than a fast connection.

Planning your Idaho drive
The shortest saved route in this guide is 7.3 miles; the longest is 130.78 miles. Choose one itinerary first and account for travel to its start and back from its finish. These are separate route picks, not an automatically connected road trip, and some can share road sections.
Check official Idaho traffic and road closure resources before leaving. Park entry, timed reservations, vehicle restrictions and visitor-site permissions can be separate from whether the public highway is open. Follow current local instructions over an old map or article.
How we chose these Idaho roads
This is a focused selection from the curated RevRoutes Explore catalog, ordered editorially for driving character and reputation, not mileage. We do not pad every state to the same number of picks; more roads remain available in the app. It is not an objective ranking or a claim that the editorial team has personally driven every itinerary. Distances describe the exact saved catalog lines and can differ from official byway lengths. The maps are planning aids—not live navigation or road-condition reports.
