Take the Sinbad Creek trail to the Shady Creek Trail to the Bay Leaf Trail.
The directions lead to a private area with signs that says no access. You should start the trail from Foothill stage area on the other side. The drive to the no access point is very beautiful though. We did not do the trail.
