After the Safeway headed to the west end of Christopher Park. There's a short trail down to a bench where the longest of the Canyon trails starts its descent to the right (first pic), with an awesome vista of Mount Davidson across the Canyon (second pic). This one's my favorite upper trail: steepish, wood steps (about 86) and dirt trail, with a few turns (third pic). It continues to the Canyon floor (fourth pic: last steps down) to emerge just past the footbridge. Pics 5 and 6 are of some Canyon trails from O'Shaughnessy.
Was sitting on a rock at the side of the main trail down here when I met a very nice couple with the seventh (most recent) edition of Adah Bakalinsky's "Stairway Walks in San Francisco" book.
Continued on to "my" secluded northernmost trail for some juicy fat ones, my reward for climbing over tree limbs and getting pricked by brambles.
After climbing out of the Canyon onto the walk that ascends to Turquoise (seventh pic), turned left to Quartz ... to Amber ... to Amethyst ... to Red Rock (last pic: a house I like on Red Rock). Then to Cameo (a few yards from the top of the Coralino stairway), Duncan, and the end of Diamond Heights Blvd. where it meets Clipper and Portola 300, with a stop for the #52 Excelsior. Across the street begins the Twin Peaks neighborhood. Right around here is this tall brown wood sculpture (on the Diamond Heights side) that's been here many years and I still have no idea of its history.
