Owyhee Lake Road is a narrow, winding 22. 8-mile paved route with very narrow sections and moderate steepness that provides access to Owyhee Lake and Lake Owyhee State Park in Malheur County.

The road runs along the scenic Owyhee River canyon but presents significant hazards including unlit tunnels, lack of guardrails (elevated 60 feet above water), rockfall risks, and potential mudslide closures during severe weather—requiring cautious driving.

The road leads to developed boat ramps and campgrounds at Lake Owyhee State Park, making it the primary vehicle access for boaters and anglers visiting the reservoir.
