The hike starts at the same limited parking lot on the east side off Highway 1. From the parking lot you can hike toward the Rangers Residence or take the cut-over trail toward the Gray Whale Cove trail.
The old Pedro Trail Mountain Road is similar to the North Peak Access Road -- it was a former paved road that has slowly eroded away leaving a decent trail surface.
The trail intersects with the North Peak Access Trail, if you stay to the left you will travel on a rarely used trail around one of the hillside peaks. After this it will meet up again with the North Peak route and finally veers off to the left. This final intersection is well marked, but make sure you follow signs for "Old Pedro Mountain Road - Pacifica".
