At the 70th step up from Hearst is a major street, Monterey Blvd. Cross Monterey at the crosswalk and continue up the steps alongside the apartment building (foto) for 185 steps total up to Joost. There’s a lot of wild fennel and you’ll walk past the back doors of residences.
Sunnyside’s south border begins around City College/Judson; its east side borders Glen Park. North of Sunnyside Playground is the Miraloma Park neighborhood, and to the west is Westwood Highlands.
The #43 is a good bus to take you up and over from the north side; winding down the west side and through part of the Sunnyside out past City College. When visiting Mount Davidson Park, sometimes get off at the Juanita/Marne stop, walk a couple blocks uphill, and ascend the brick Juanita stairway, the north trailhead for the zigzag trail through the forest to the summit.
