Wallace to Pullman: Scenic Idaho Drive Guide

At the intersection of Silver Valley's mining past and the Palouse's rolling wheat fields lies a drive that compresses two distinct worlds into 101 miles. Starting at the historic Wallace Depot (elevation 2,748 feet), you'll climb over the Bitterroot crest at Lookout Pass (elevation 4,730 feet) before descending to the fertile Palouse. The route includes US-90 for 8 miles, then ID-3 north to the Washington state line, then WA-27 to Pullman.

One quirk: the Idaho state line appears twice; you briefly enter Washington near Tekoa before re-entering Idaho for 12 miles, then crossing back into Washington. This administrative oddity is a fun detail for map nerds.

Natural landscapes along this route include the Silver Valley's steep hillsides, the Cœur d'Alene River's turquoise waters, and the endless wheat fields of the Palouse. In spring, the first cutting of hay creates striped patterns on the rolling hills.

• Climate: Wallace averages 36 inches of snow annually; Pullman receives 12 inches, but winds are stronger.

While no UNESCO World Heritage Sites lie directly on this route, the nearby Cœur d'Alene Mission at Cataldo is on the National Register of Historic Places, notable as the oldest standing building in Idaho (1853). Local commerce thrives in Wallace's Silver Streak Zipline and the high-tech amenities at Pullman's Washington State University, home to the Creamery. For a bite, order a Cougar Gold cheese sandwich at WSU's Ferdinand's Ice Cream Shoppe.

How long to drive Wallace, ID to Pullman, WA is a common question: the 101-mile route typically takes 1 hour 40 minutes without stops, but plan for 2.5 hours to enjoy viewpoints and small towns. Is it worth driving Wallace, ID to Pullman, WA? Absolutely, because the route offers dramatic mountain to prairie transitions rarely seen in such a short span.

• Fuel: Gas in Wallace (~$3.50/gal) and Pullman (~$3.60/gal) are similar; only '66 Station in Tekoa may be pricier.
• Road conditions: I-90 is well-maintained; WA-27 is a paved two-lane road with occasional frost heaves.
• Services: Restrooms at Interstate Rest Areas (mile 43 on I-90) and Pullman city parks.

The Palouse is a designated National Scenic Byway, but the most pastoral stretches begin south of Pullman, not on the direct route. For a scenic alternate, take WA-272 from Colfax to Pullman, but that’s off our fast path.

Infrastructure safety on I-90 is top-rated, but WA-27 requires vigilance for farm equipment. There are no rest areas on WA-27; instead, plan fuel stops in Tekoa (mile 70) or Colfax (mile 82).

• Family suitability: The Sierra Silver Mine Tour in Wallace is child-friendly; hiking trails at Steptoe Butte State Park (south of Pullman) are easy for all ages.
• Pet-friendly: Many Pullman parks allow dogs on leashes during summer.

For fatigue management, set a timer every 2 hours and stop at the Larkins Roadside Viewpoint (mile 67) with benches. Hidden off-route spots include the Palouse Falls State Park (watch out for gravel roads) and the Olson Mansion in Tekoa. For planning, consult how to find the best stops and hidden gems between cities to locate off-the-grid overlooks. Best stops Wallace, ID to Pullman, WA include the Cataldo Mission and the Humble Burger in Colfax for a milkshake.
