The Lower Salmon River Trailhead Access is located at Manning Crevice Bridge, the second bridge crossing the Salmon River on Forest Road 1614 east of Riggins, offering access to a 5.

4-mile riverside trail with historical significance dating to the 1860s gold rush era. Parking is extremely limited at the bridge, so visitors should plan accordingly and avoid blocking the road.

The trail follows the north side of the river with some rocky sections and exposed areas, making early morning or late afternoon hikes preferable during summer months.
