Two more new signs have been added at this trailhead: "Quiet please up to the Forest 125' " and "Quiet down to the Street 125' " (it starts off between homes on Stanyan): second pic. This trail's between two others just recently hiked.
The lower Historic winds up 'n around (pics 3 through 6) and connects with the Fairy Gates and Edgewood Trails.
Crossed the road at the end of the Fairy Gates (pic 7) to continue steeply up, past the nursery and onto the short, unmarked Quarry Road Trail. At the end of this is a marker for the upper Historic Trail.
Paused for lunch on the Historic at a favorite rock just off the trail (pics 8 and 9), curving around to the north with the hospital buildings seen below through the trees, and down to the road.
A THEN pic (10): the grand opening of the newly discovered and renovated Historic Trail back in 2007, a free grouphike. This was the way we first reached the trail back then, alongside the tank; now the trailhead looks like this: pic 11.
From here it's a short distance through the permits-only parking lot to descend the attractive woodrailed, wood-and-concrete stairway (135 steps: pics 12 through 16). At the foot, just follow Medical Center Way around from the backs of the hospital buildings out to busy Parnassus.
