-- Second pic: Part of Andy Goldsworthy's Wood Line installation, center, just off Lover's Lane.
-- Moving west, third pic.
-- Pics 4 and 5: Foot of the steps (69) on the west side of El Polin Springs. Climbing these to the Ecology Trail: pix 6, 7, 8, 9.
-- Continuing up: Ecology Trail through a forested part, pic 10.
-- Old wood steps (45) from Ecology Trail up to Inspiration Point Overlook (off Arguello), pics 11, 12, 13.
-- Pic 14: Marine Cemetery Vista Memorial stairs (103), west side of Park Presidio Blvd. up from 14th Avenue/Wyman to the boardwalk, memorial plaque, and benches, out to Battery Caulfield Rd.
-- Pics 15, 16, 17: Connector Trail, 208 wood steps down from Immigrant Point Overlook to Lincoln.
-- Crossing Lincoln and starting down from Lincoln for the Batteries to Bluffs Trail (473 or so wood steps, not counting the 16 or so up to Battery Crosby at the top of the main stairway), west to east, pix 18 through 24. This is San Francisco's longest stairway. The railings on the steep west side were a later addition.
Last one is looking down from Lincoln at people on the BTB's View Point overlook.
Another long stairway that can be accessed from Lincoln nearby (or from Baker Beach at its foot) is the infamous Sand Ladder (often difficult to count the steps as some may be buried underneath the sand -- but at least 250).
