Headed north on Levant a block or so to the States/Levant stairway (45 steps), the top at Roosevelt. A short distance east on Roosevelt is the west entrance for Corona Heights Park where the foot of a stairway can be seen to the right. Starting from this west side, 100 steps will take you nearly to the summit rocks (second pic: Buena Vista Park in the near distance). Several years ago some new steps were added. Partway up, turn left. (There's another trail around to the right, also with new steps.)
At the summit rocks, a short trail leads to 41 more steps (third pic) and it turns once again to the lone bench up here (fourth pic: 61 steps this side so far).
Much of the main stairway (fifth and sixth photos) down this east slope is older and uneven. But at the foot are some replacement steps (seventh pic) down to the Randall Museum's east stairway. So since this stairway just keeps going, continuous, with a bit of dirt trail at times, I'm inclined to call the whole thing, west to east, one stairway, with about 290 steps total.
The Randall Museum (eighth pic) is open to the public Tuesday through Saturday from 10 to 5; closed Sundays and Mondays. My favorite animal today was their new little possum, gazing out at me from inside his shelter towards the back of the cage. There are various critters living here that are currently unable to survive in the wild, including a duck, chickens, a rabbit, ravens and other birds.
Down the east Randall steps to a steepish trail of rough concrete to exit the park. Behind an attractive brown-shingled house, someone has started gardening at the edge of the park. To one side of the house is the top of De Forest: 18 narrow, enclosed steps down to 100 Beaver. From here it's a short distance downhill to Castro where a #24 Divisadero bus stop is at 15th & Castro.
