Overview
Kelly Forks Trail loops through one of the most ecologically significant areas in Clearwater National Forest, the confluence of Kelly Creek and the North Fork Clearwater River. Both streams are designated wild fish sanctuaries supporting native salmon and steelhead recovery, and the surrounding old-growth cedar and fir forest is among the finest in north-central Idaho.
The 5.0-mile loop gains a modest 600 feet, making it one of the more accessible loop hikes in the Clearwater forest. The combination of river views, old-growth forest, and wildlife habitat makes this a rewarding destination despite the low elevation gain.
The Route
From the Kelly Forks Campground area, the trail follows the east bank of the North Fork Clearwater River south before turning inland through old-growth forest. The loop completes by returning along Kelly Creek to the starting point. The old-growth section in the interior is the trail's highlight: massive cedar and fir trees over 300 years old.
When to Visit
May through October. The lower elevation makes this accessible relatively early in spring. The river corridor is beautiful throughout the season. Fall brings dramatic salmon returns visible in the clear water.
Practical Details
Kelly Forks Campground has vault toilets and is a good overnight base. No day-use fee at the trailhead. Water from the river requires treatment. Review Leave No Trace principles in this sensitive wild fish habitat.
Getting There
From Orofino, Idaho, drive northeast on Highway 11 and then Forest Road 250 toward Kelly Forks. The drive is approximately 45 miles and takes about 1.5 hours. High-clearance vehicles are recommended on the upper section of Forest Road 250.
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 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 Clearwater National Forest and may be unreliable in canyon bottoms or remote terrain.
