Overview
The Lochsa Historical Trail traces a portion of one of the most significant wilderness travel corridors in American history through Clearwater National Forest. The Lochsa River drainage was traversed by the Lewis and Clark Expedition in 1805 and 1806, and portions of the route follow the ancient Nez Perce trail that guided the Corps of Discovery over the Bitterroot Mountains.
The 8.0-mile out-and-back is rated moderate, gaining 1,200 feet through riparian old-growth forest along the Lochsa River. The trail stays close to the river for much of its length, and the combination of historical significance, wildlife habitat, and scenic river views makes this one of the most rewarding moderate hikes in the forest.
The Selway River Trail nearby provides a longer and more demanding river corridor experience for hikers wanting to spend more days in the Clearwater backcountry.
The Route
From the US-12 trailhead, the trail follows the Lochsa River upstream through old-growth Douglas fir and western red cedar. Interpretive signs at intervals explain the Lewis and Clark route and Nez Perce history. The trail gains elevation steadily as it moves away from the river in the upper section before returning to the water near the turnaround point.
When to Visit
May through October. The lower elevation makes this accessible before many Clearwater National Forest trails open. Spring brings high river flows and active osprey and eagle activity. Fall offers beautiful conifer colors and cooler temperatures.
Practical Details
No fee at the trailhead. The Lochsa River requires treatment if used as a water source. Dispersed camping is permitted on Clearwater National Forest lands. Cell service is limited along US-12. Review Leave No Trace principles for this historic corridor.
Getting There
From Lowell, Idaho, drive east on US-12 along the Lochsa River. The trailhead is approximately 25 miles east of Lowell on the south side of US-12. Look for the interpretive sign kiosk at the pullout.
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.
