Boise to Wallace Road Trip: Idaho's Scenic Highway 12

This 400-mile route crosses the heart of Idaho, climbing from the high desert of the Boise River Valley (2,700 ft) over a 7,000 ft pass on US-95, then descending through narrow canyons along US-12 to the historic mining town of Wallace (2,720 ft). One odd fact: near the junction of US-12 and ID-3, you'll cross the 45th Parallel, halfway between the Equator and North Pole.

Drive time is roughly 7 hours without stops, but plan for 2-3 days to fully experience the Payette National Forest, the Lochsa River, and the ghost towns. For a method to scout your own unique stops, see how to find the best stops and hidden gems between cities. This is not just a drive—it’s a journey through deep forests, hot springs, and a landscape shaped by wildfires and mining.

US-12 from Kooskia to the Montana border is one of the most remote federal highways in the lower 48. There is a 130-mile stretch without gas stations from Kooskia to Lolo Hot Springs. Fill up at the Kooskia Chevron or Kamiah Shell. Fuel prices in these towns average $0.20-$0.50/gallon higher than Twin Falls or Boise.

• Elevation changes: US-12 climbs to Lolo Pass (5,233 ft) with steep grades up to 7% for 15 miles. Engine braking recommended.
• Road quality: US-95 is well-maintained two-lane highway; US-12 is narrow with winding sections, often patched after winter. Cell service is spotty between McCall and Riggins, and completely absent east of Lowell.
• Economic reality: This route is part of the Idaho Forest Highway network, serving logging trucks. Expect occasional delays near sawmills.

For those asking is it worth driving Boise to Wallace, yes, especially if you love unspoiled nature. But plan carefully: the best stops Boise to Wallace are often off the main route—like the ghost town of Burgdorf or the hot springs at Jerry Johnson. For how long to drive Boise to Wallace, budget at least 9 hours of pure driving, but you'll want 2-3 days to explore.

The route features Payette National Forest, Selway-Bitterroot Wilderness, and the Lochsa River. But the standout is the Wallace Historic District, a National Historic Landmark District with 30 blocks of restored 19th-century buildings. Though not a UNESCO World Heritage Site, Wallace is on the tentative list for its intact mining-era architecture.

• Natural Landscapes: Watch for the Ponderosa pines and wildflowers like arrowleaf balsamroot in May. The Lochsa River is one of the wildest whitewater rivers in the US.
• Local Commerce: In Kamiah, stop at the Nez Perce Smoke Shop for artisan beadwork. In Wallace, the the historic Oasis Bordello Museum is a quirky local business turned museum.

If you're searching things to do between Boise and Wallace, consider kayaking on Payette Lake outside McCall, or a short hike to the Lochsa Falls. The how to find the best stops and hidden gems between cities method works exceptionally well here, because many stops aren't on typical tourist maps.

US-12 between Lowell and Lolo Pass has no cell service and only two primitive rest areas. Plan for breaks at the Lochsa Historical Ranger Station (milepost 10) which has restrooms and picnic tables. For families, the St. Joe River Recreation Area just south of Wallace offers easy trails and a small beach.

• Fatigue management: The monotonous curves of US-12 can cause hypnotic fatigue. Stop every 90 minutes. Best rest zones: Ponderosa State Park (McCall) and the Lolo Pass Visitor Center.
• Pet-friendly infrastructure: Most stops allow pets, but the only off-leash area is the McCall Dog Park at milepost 60 on US-95. Many campgrounds along US-12 are pet-friendly.
• Infrastructure Safety: In winter, chains or studded tires are required over Lolo Pass. Summer brings wildfire smoke; check Idaho Smoke Blog.

Hidden off-route spots include Jerry Johnson Hot Springs (2-mile hike, clothing optional) near milepost 34 on US-12, and the St. Joe River Scenic Byway that leads to the ghost towns of Superior, Montana. For culinary breaks, the Lochsa Lodge serves hearty breakfasts, and in Wallace, the Blackboard Bistro offers farm-to-table.
