The first I'd found on the map was called Locust. It is indeed a stairway after the first two blocks (first pic), but seemed longer to me on Google Maps than it did when actually walked, with 16 steps (pic 2) to start, up to a steep vehicle street (pic 3). Then an all-wood stairway up to Cazneau: pics 4, 5. About 74 steps total.
Sixth pic: House on Cazneau.
Seventh pic: A view from Woodward.
Eighth pic: Down from Woodward to Marie, 20-something old wood steps with two benches at the foot.
Pic 9: Bonita to Napa/Filbert, 20 or so steps.
Pic 10: 28 more steps continuing up to Filbert. This and #9 are close together.
11th pic: A steep railed walk with two chairs at the foot of another short stairway (28 steps) up to Girard from Bonita: Bee street.
Pic 12: House on Girard near Filbert.
Pic 13, 14: Views from two homes on Glen. It's like walking around in a treehouse all over this whole area.
Pic 15, 16: Started up a very old wood stairway (80 steps) that had a loose wood railing a little way up. It curved around so no clue if it was private. It turned out to be through with a few flagstones at the top of the stairs where a steep street with rails on two sides took me out to Cazneau & Platt (pic 17).
Up here it's not wise for hikers to wear earbuds since you need to hear cars behind you, there being no sidewalks on some of the winding streets and barely enough room for cars to navigate. George Lane is so narrow (pic 18) that signs advised "No parking at any time" and 15 MPH speed limit.
Followed handsome George as it curved around but no way down at the upper end (pic 19) so started back, slowly circling downhill on gorgeous Glen. I like the open all-wood decks that are next to some of these urban-forest homes, adding to the treehouse look: like this one at the top of the aforementioned old wood stairway out to Cazneau: pic 20.
Last pic: Coming into San Francisco. Our Mount Sutro is highly visible from a long way off. The ferry takes less time than some of the buses I put up with.
