This part of 22nd is said to be tied for SF's steepest street grade with Filbert (and the two Filbert sidewalk stairways) on Russian Hill between Leavenworth and Hyde: at 31.5 degrees.
The stairway on the south side of 22nd has around 146 steps (first two pics) and the one on the north 143 (third pic), same as a previous count a couple of years ago. The Botanical mural on the northside wall could use some touching up.
Up the south steps, then down the north, heading for Sanchez and the two 20th Street stairways I'm especially fond of in this 'hood.
For hillwalkers who go for the really steep ones, the next two regular streets to the north, Hill and 21st, are good ones to huff up. There should've been stairways here too. I'd like to see a pocket-sized device that'd digitally, without any calculations on my part, tell me exactly how steep stairways/streets/trails are as I hike 'em. Like the last blocks of 28th and 29th from Noe Valley up into Diamond Heights f'instance.
Trudged up supersteep 21st to get to Sanchez. Downhill a little from here to get to the top of the Sanchez steps: 34 down to 745 Sanchez at 400 Liberty. If you want to do the Liberty stairway (Rayburn down to Noe), it's nearby to the west. Today continued on divided Sanchez's upper part (fourth pic) to the first of the 20th Street stairways: 62 steps to 20th (fifth and sixth pics). Then a short distance to the west to descend the steepish stairway to Noe alongside an apartment building (80 steps: seventh and eighth pics).
On Noe a short stroll (north) took me to the Cumberland stairway (41 steps: 10th pic). Up from Noe on Cumberland will take you back to Sanchez.
Sanchez down from Cumberland has 29 sidewalk steps on the east side (11th pic) and some on the west side. These lead down to the stairway (12th pic) that will take you to 19th Street: around 74 steps from the Sanchez dead-end-for-cars viewspot down to 19th. The Pride mural on the apartment building at the corner of 19th & Castro is still there (last pic).
