Climbing from Bay St. and Larkin is Russian Hill Park, 75 steps to start: 1 thru 17
I count these three stairways as one long as they connect and continue from Bay nearly to Chestnut.
The second flight has 59 steps that ascend alongside the old reservoir: 18 thru 32
This area is a popular place to watch the Blue Angels.
The third and final flight rises up from Francisco St. nearly to Chestnut, 26 steps: 33 thru 40
So 75 + 59 + 26 = 160.
A right turn will take y9u to the top of the Chestnut stairway (116 steps): 41 thru 55
At the foot of the Chestnut steps, a left on Culebra Terrace: 56 thru 60
The 32 steps at its south dead-end for vehicles will take you up to Lombard: 61 thru 70
Part of an old mural on the side of a vacant grocery at Clay & Polk (starting up Nob Hill) that has now been partially painted over. So here's some of it before it's completely gone: 71 thru 74
