Salmon River Scenic Byway 160 miles
- Idaho’s Salmon River Scenic Byway is an official 161-mile route, not a vague social-media loop, running from Stanley to the Montana line via Challis and Salmon. - The route’s real draw is its mix of river access, hot springs, and mining-history stops — from Goldbug and Challis Hot Springs to Yankee Fork. - That matters because it’s a quieter central Idaho drive with enough official infrastructure to turn a pretty detour into a real trip.
The Salmon River Scenic Byway is a real Idaho route with a real footprint — and the details are better than the viral shorthand. It runs 161 miles, following ID 75 and US 93 from Stanley through Challis to the Montana state line. That matters because a lot of the appeal here is not just “nice views.” It’s that the road stitches together river scenery, hot springs, ghost-town history, campgrounds, and trail access in one continuous drive.

The official route starts in Stanley, heads northeast on ID 75 to Challis, then continues north on US 93 through Salmon and up to Lost Trail Pass at the Montana border. So if you saw “160 miles,” that’s basically a rounded version of Idaho’s official 161-mile number, not a made-up influencer estimate. (visitidah([visitidaho.org)re people fixating on this drive? Because it compresses a lot of Idaho into one road. The byway follows the Salmon River for long stretches, with the Sawtooth Mountains near the southern end and the more rugged, less-trafficked country around Challis and Salmon farther north. Visit Idaho pitches it as a road trip with natural hot springs, gl(visitidaho.org)in motion or stop every hour. (visitidaho.org) ### What are the real anchor stops? Challis is one of the big practical hubs. It sits near Land of the Yankee Fork State Park, which ties the route to Idaho mining history and the old town of Custer. The state park also notes that Challis Hot Springs became part of the park in 2022, which matters because it turns one of the route’s classic stops into a more formal, bookable destination instead of a purely word-of-mouth one.

Challis Hot Springs sits right off the corridor and takes reservations through Idaho State Parks. Goldbug Hot Springs is farther north, just south of Salmon near Highway 93, but the catch is that it is not a roadside soak. (parksandrecreation.idaho.gov) quick pullout. (getoutside.idaho.gov) ### Is this more than a hot-springs drive? Definitely. The route also works as a base for camping, fishing, rafting, and hiking. Recreation.gov’s Salmon Field Office page leans into the region’s more isolated feel and notes wildlife-rich terrain and fishing along the Salmon River. The Salmon-Challis National Forest pitches the broader area around the byway as a place for campgrounds, scenic drives, historic sites, and Wild & Scenic river access. (recreation.gov) ### So is it a good summer alternative? Basically, yes — if what you want is scenery without the full national-park conveyor belt. This is still a rural Idaho road trip, so services are more spread out and some marquee stops require planning. But that’s also the point. The byway has enough official structure — mapped route, reservable hot springs, state park stops, federal recreation ac(recreation.gov)directed than the West’s busiest summer corridors. (visitidaho.org) ### What’s the bottom line? The viral version is mostly right, but undersells the route. The Salmon River Scenic Byway is not just a pretty 160-ish-mile drive. It’s an official 161-mile corridor that links Stanley, Challis, Salmon, hot springs, campgrounds, and mining-country history into one of Idaho’s most complete road trips. (visitidaho.org)
