Salmon to Wenatchee: Epic Idaho-Washington Road Trip Guide

This road trip traces the route of the Nez Perce War of 1877, as Chief Joseph led his people across the same rugged terrain you'll traverse. The drive spans approximately 350 miles between the Salmon River's gold-rush past and Wenatchee's apple orchards.

You'll cross the Continental Divide twice, climb from 4,000 to over 7,000 feet, and pass through climates ranging from arid sagebrush to pine forests and river valleys.

Begin on US-93 North from Salmon, then turn onto ID-28 toward Tendoy. Continue to ID-33 West to US-20, then US-26 West to OR-201 and I-84 West to US-395 North. Finally, take WA-240 into Wenatchee.

Alternative scenic route: US-93 to Missoula, MT, then I-90 West to WA-28, adding 1-2 hours. For fuel, plan stops at Challis, ID; Arco, ID (has several stations); Idaho Falls; Twin Falls; Ontario, OR; Pendleton, OR; Kennewick, WA; and Wenatchee—gas prices vary widely, with Oregon often cheaper than Idaho.

• Check weather: Mountain passes like Lolo Pass (elevation 5,233 ft) may close in winter.
• Carry chains from October to April.
• Most services close early in small towns, so fill up before dusk.

Most highways are well-maintained two-lane roads with occasional passing lanes. Watch for wildlife, especially deer and elk at dawn and dusk. The Lolo Pass road has steep grades and curves, so use lower gears to avoid brake fade.

For fatigue, plan to stop every 2 hours. Excellent rest areas include: the one at Lolo Pass (with interpretive signs), the Nevada Street Rest Area in Pendleton, OR, and the Vantage Rest Area overlooking the Columbia River.

Family-friendly stops: the historical museum at the Sacajawea Interpretive Center in Salmon, ID (small fee, interactive exhibits), and the Hershel's Giant Rubber Band Ball in Pendleton (free, quirky). For kids, the Columbia River Exhibition of History, Science, and Technology in Richland, WA, features a full-scale science theater.

Pet-friendly: Most rest areas have leash-free zones. In Pendleton, the Woolgrowers Restaurant allows well-behaved dogs on its outdoor patio. Be aware that some state parks require pets to be on a 6-foot leash.

Hidden gems: Take a short detour to the ghost town of Golden, ID (off US-93), an abandoned mining settlement with a few intact buildings. Continue to the Box Canyon of the Salmon River overlook for a dramatic view of the river's narrowest point.

The Salmon River Valley offers dramatic canyon views and hot springs like those at Challis (primitive soaking pools, free). Farther north, the Lolo Pass area contains ancient cedar groves and part of the Nez Perce National Historic Trail. The route passes near the Columbia River Gorge, known for its windsurfing and waterfalls.

UNESCO World Heritage Sites: none on the direct route. The closest is Yellowstone National Park (via US-20) but it's a significant detour. Instead, visit the Nez Perce National Historical Park in Spalding, ID, which preserves 38 sites significant to the Nez Perce people.

Local commerce thrives in small towns like Kamiah (known for its whitewater rafting outfitters) and Orofino (home to the Clearwater River casino). In Washington, the Tri-Cities area offers wineries, and Wenatchee is the world's largest apple producing region, with over 300 orchards.

The route passes through several distinct climates: arid high desert in Idaho, maritime-influenced forests in Oregon, and semi-arid shrub-steppe in Washington. The best time to see fall colors is late September to October.
