Idaho Falls to Athol Road Trip Guide: Best Stops & Hidden Gems

This 400-mile northward journey from Idaho Falls (43.4916° N, 112.0338° W) to Athol (47.9477° N, 116.7072° W) traverses the Snake River Plain, crosses the Continental Divide at Monida Pass (6,860 ft), and descends into the forested Panhandle. The route follows US-20 west to I-15 north, then connects via US-95 and ID-53. Driving time is approximately 6.5 hours without stops, but the real adventure lies in the detours.

Idaho Falls sits on the Snake River, named for its cascading waterfalls. Athol is the gateway to Silverwood Theme Park, one of the largest amusement parks in the Northwest. The drive reveals volcanic landscapes, pioneer history, and abundant wildlife. For tips on finding hidden stops, see how to find the best stops and hidden gems between cities.

Total: ~400 miles, 6.5 hours driving. Add 2–3 hours for key stops.

Wildlife hazards: Deer, elk, and moose are common at dawn/dusk, especially on US-93. Use high beams when safe. Snow possible from October to May; check weather for Monida Pass closure updates. Carry chains in winter.

Rest zones: Every 2 hours, take a break. Recommended stops are Dubois Rest Area (mile marker 190 on I-15) with picnic tables, and Salmon River Rest Area on US-93 south of Salmon (shade, toilets). For longer breaks, Craters of the Moon has shaded picnic spots.

Family-friendly attractions: Silverwood Theme Park in Athol (summer) with roller coasters and water park. En route, the Idaho Potato Museum in Blackfoot (just off I-15 at exit 94) showcases potato farming history – kids love the giant potato chip. Movie theaters in Dillon and Coeur d'Alene offer rainy-day fun.

Pet-friendly framework: Most national forest lands allow leashed dogs. Craters of the Moon permits dogs on paved trails but not in backcountry. Hotels in Idaho Falls, Dubois, and Coeur d'Alene have pet-friendly policies. Carry water and waste bags for desert sections; rattlesnakes are rare but present.

Culinary stops: For authentic Basque cuisine, the Basque Block in Boise is far south; closer to route is the Snakebite Restaurant in Idaho Falls (wild game). In Arco, Pickle's Place serves homemade pies – try the huckleberry. For a taste of Idaho huckleberry treats, stop at Huckleberry Heaven in Coeur d'Alene.

To combat driver fatigue, use the 20-20-20 rule: every 20 minutes, look 20 feet ahead for 20 seconds. Share driving if possible. Audiobooks or local podcasts (e.g., Idaho Matters) keep the mind engaged.

Volcanic landscapes dominate the first leg. Craters of the Moon National Monument and Preserve (43.4299° N, 113.5465° W) protects a 618-square-mile lava field formed by eruptions 15,000 years ago. Drive the 7-mile loop road to see cinder cones, lava tubes, and the eerie "Tree Molds" – hollows where trees were engulfed by molten rock. No entry fee in winter; $20 per vehicle in summer.

Further north, the Centennial Mountains along the Montana-Idaho border offer alpine meadows and grizzly bear habitat. At Monida Pass, look for the historic stagecoach station ruins. The Bitterroot Mountains along US-93 are a birder's paradise with bald eagles and peregrine falcons.

• Best photo spots: Inferno Cone overlook at Craters, Red Rock Pass vista, Lost Trail Pass (elevation 7,014 ft).
• Local produce: Huckleberries in late summer near Coeur d'Alene; find jams at farm stands on ID-53.
• Art galleries: Salmon's Sacajawea Interpretive Center (tribal artistry) and Coeur d'Alene galleries on Sherman Avenue.

The route also passes through the Fort Hall Indian Reservation (Shoshone-Bannock) and Nez Perce ancestral lands. Respect tribal sites; photography restrictions may apply.

The route is primarily interstate and US highways, well-maintained with occasional construction in summer. Fuel stations are plentiful in towns every 30–50 miles, but sparse between Arco and Dubois, and between Lima and Salmon. Plan to fill up in Idaho Falls, Arco, Dubois, Dillon, and Salmon.

Key highway junctions: US-20 at Idaho Falls, I-15 at Dubois, US-93 at Salmon, I-90 at Coeur d'Alene. The most scenic segment is US-93 from Salmon to Lost Trail Pass, winding through the Bitterroot Mountains.

• Fuel economy: Expect 22–28 mpg on mostly level terrain, dropping on mountain passes.
• Tolls: None on this route.
• Restrooms: Available at Craters of the Moon visitor center, Dubois rest area, Dillon truck stops, and Salmon.
• Cell coverage: Good near towns; spotty in mountain sections like Lost Trail Pass.
• Road quality: Excellent asphalt on interstates; US-93 is winding but paved.
