Devils Bench Boat Ramp offers two concrete ramps with an 8-degree grade immediately upstream of Lower Monumental Dam, making it an ideal portage point for non-motorized vessels.

The site features a large paved parking area (20 car spaces, 10 marked trailer spaces), vault toilets, picnic tables with fire rings, and campsites, though there is no potable water or cell service.

This free access point is essential for paddlers navigating the Snake River and provides a scenic riverside camping area with views of the dam.
