The parking lot is located on Page Mill Road, 7 miles west of Highway 280 and 1.5 miles east of Skyline Boulevard. It is slow going, I figure 30 minutes drive up Page Mill from 280. Important: the address on the google map is about a half a mile east of the parking lot. If you are coming from 280 and have the address plugged into a GPS, continue a half mile further. If you are coming from skyline, look The parking lot will be on the left. If you are using a GPS, plug-in Latitude 37°19’32.64″N and Longitude 122°10’44.55″W.
