Hazard Details: Trail from Potato Harbor Overlook to Montañon Ridge is not maintained. Loose, rocky terrain with steep scrambling sections. Relentless sun exposure with minimal shade. Limited trail markers require strong map navigation skills. Exposure on ridge sections demands caution and careful footing.
Best Season: Spring (March–May) and fall (October–November).
Best Time To Visit: Spring (March–May) or fall (October–November) for stable weather and lower heat exposure. Start by 6 AM to finish in daylight; the unmaintained sections slow pace. Afternoon winds can be brutal on exposed terrain.
