The St. Joe River National Recreation Trail in St. Joe National Forest follows one of Idaho's most celebrated rivers through old-growth cedar and pine forest in the Panhandle. The eight-mile round trip is moderate in difficulty, gaining only 400 feet as it follows the river upstream through a valley that showcases the finest character of the northern Idaho forest.
The St. Joe River holds the distinction of being reputedly the highest navigable river in the world, originating in the Bitterroot Mountains at an elevation that is remarkable for a river navigable by small watercraft. The National Recreation Trail designation recognizes the outstanding quality of the river corridor.
The Route
The trail begins near Avery and follows the St. Joe River upstream through alternating sections of old-growth forest and river-edge open terrain. The cedar and white pine canopy in the old-growth sections is massive, with trees several centuries old and base diameters that dwarf the surrounding younger forest. The river is accessible throughout.
Cutthroat trout are visible in the clear water at multiple pools along the trail. Osprey fish the river regularly, and river otter have been documented throughout the St. Joe watershed.
What to Expect
This trail is primarily a river and old-growth experience. The elevation gain is minimal; the payoff is the sustained quality of the scenery along one of Idaho's finest rivers. Late summer visits in August and September provide the clearest water and the best fish visibility.
The trail surface is generally good with some rocky sections near the river's edge. High water in May and June can submerge some riverside trail sections; alternate routes are usually available.
Nearby
Avery, Idaho, is a small community near the trailhead and serves as a base for St. Joe River recreation. St. Maries, about 35 miles west on ID-3, is the nearest town with full services. The St. Joe River corridor is popular with anglers, kayakers, and river campers who all share the valley.
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.
