Overview

The Salmon River Corridor Trail follows the banks of one of Idaho's most legendary waterways through Challis National Forest. The 7.0-mile out-and-back gains only 400 feet, making it one of the most accessible routes in the Challis area and a good option for hikers wanting a scenic river walk without the demands of the mountain trails.

The Salmon River earns its nickname "The River of No Return" from its historically un-navigable canyon: trappers and miners could float downstream but could not return by river. Today, the river corridor is a world-class steelhead fishery and supports abundant wildlife including osprey, bald eagles, and great blue herons.

For those wanting more challenge in the Challis area, the Germania Creek Trail or the high-alpine routes in the White Clouds provide good complements.

The Route

From the trailhead off US-93, the trail follows the river through willows and cottonwood. The river is visible or audible throughout. Fishing access points are marked along the route.

The return retraces the outbound route. Evening walks offer the best light on the river and peak activity from bald eagles and osprey.

When to Visit

May through October. Spring flows are dramatic with the river running high and swift from May through June. Summer offers warm weather and calmer conditions. Fall is excellent for fall color and fishing season.

Practical Details

No facilities at the trailhead. Carry water (the river requires treatment). Dispersed camping on Challis National Forest lands. A valid Idaho fishing license is required to fish. Review Leave No Trace principles.

Getting There

From Challis, drive north on US-93 and watch for the Salmon River Trailhead signs. The trailhead is approximately 5 miles north of town.

Leave No Trace

This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.

Safety Considerations

The easy-moderate rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Challis National Forest and may be unreliable in canyon bottoms or remote terrain.
