Owyhee Lake Road is a scenic 22.

8-mile paved route (built in 1930s) that winds along the Owyhee River to Lake Owyhee Reservoir, featuring narrow sections, steep grades, and unlit tunnels with rockfall hazards—drive cautiously as the road lacks guardrails and sits 60 feet above water.

The road provides access to Lake Owyhee State Park with multiple boat ramps (Indian Creek and Gordon Gulch day-use areas), camping at McCormack and Indian Creek campgrounds, and fishing opportunities, though mudslides from thunderstorms can occasionally block the route.
