The road extends out of the “viewpoint” parking lot side walk. Drive down about half mile, of east dirt road, to the green park limit fence. We don’t have a 4x4, but managed to drive just past fence and park for the night (RAV4, 2WD, rooftop tent). Super quiet. No one drove by at night. No ATVs, motorbikes or street illegal cars allowed, therefore I’d imagine there is a dearth of traffic. No cell phone signal. Parking lot has bathrooms.
