Selway River Trail #4 begins at Race Creek Campground, accessible via Route 223 near Lowell, Idaho, and serves as the western trailhead for the 56-mile Selway River Trail.

The trailhead offers an outhouse but no potable water, so visitors should bring water or have treatment capability.

This access point is ideal for day hikes (the first 6 miles are particularly scenic) or backpacking trips, with abundant campsites and river access along the trail, though be aware of rattlesnakes in the area and that the trail involves rolling terrain with steep sections despite gradual overall elevation gain.
