7 of us took two cars and 3 bikes and left Pacific Palisades at approximately 4pm. The total distance was 177 miles and took us approximately 5.5 hours, which included a 30 minute stop for food.
About 50 miles of the drive is on dirt roads along the San Andreas Fault.
The next morning, we woke early and drove 10 miles to the turnoff, and 10 miles up the hill to where we found one last canyon filled with Wildflowers. Two weeks later, they had all disappeared.
