Up ahead, the trail crosses a small creek. Look for the white Oakland star tulip. 0.3 Post 4 and junction. There are several unofficial crossing trails. Continue right on the main trail.
Numbered posts mark the way.
After climbing a knoll offering grand views south, the trail drops down to a road. Continue across the road to Turtle Rock. From the south side of the rock, take the footpath uphill to the east, aiming to the right of the water tank. Continue across the road and head uphill on the unofficial trail, which soon passes over a white serpentine outcrop. The trail meets the road, but again, leave the road and head right, up towards the highest point.
