Owyhee Lake Road is a scenic 22.

8-mile paved route from Owyhee to Lake Owyhee Reservoir featuring narrow sections, steep grades, and unlit tunnels carved into canyon walls—drive cautiously as the road lacks guardrails and sits 60 feet above water with hazards including rockfall and mudslide risks.

The road provides access to Lake Owyhee State Park's boat ramps and camping facilities, making it the primary vehicle route to the reservoir for boating and fishing recreation.
