How far can you go with a vehicle before you have to go on foot? I was looking it up on google maps, but when I try to do directions it changes the location to a neighborhood right next to it. Do we park there and hike it up? Or can we drive all the way up?

For clarification, this link shows the changed location to Sneath Ln. http://maps.google.com/maps?q=37.61336,-122.458903+(Nike+SF%2D51c+%5Bexact%5D)&hl=en&t=k
I am just curious, as I do not want to waste time seeing that I am trying to see as many places as possible when I go up North.
