Started off at 7th Ave. and Warren. After a few uphill blocks on Warren in the Forest Knolls neighborhood, the mighty green Oakhurst stairway begins its ascent to Crestmont (first four pix, about 353 steps).
From the top of Oakhurst at Crestmont and a short curve to the north is the unmarked trailhead for the steepish West Ridge Trail (fifth pic). It comes out at the Historic Trail (pic 6) and continues up.
Pic 7: Top of the West Ridge Trail at the summit.
Continued on the Historic (pics 8, 9) to the turnoff for the summit; my favorite sitting spots were taken.
Down the East Ridge Trail (pix 10, 11, 12) to its foot. Looking down from Medical Center Way's pedestrian walkway (pic 13), you can see part of the Fairy Gates Trail. On to the trailhead for the Fairy Gates. A short distance along is a trail marker for the lower Historic Trail (14 through 19). It was disturbing to see the notice-to-spray-pesticides sign near pic 19 where the green park infosign is.
Pic 20: The Edgewood Trail across as seen from the lower Historic. This beautiful trail leads out to the south dead-end of redbricked Edgewood Avenue. At the north end of Edgewood is the top of the Farnsworth stairway (149 steps), down to Willard.
Pix 21, 22: The short wood stairway down to Stanyan. At street level is the Interior Greenbelt's trails infosign (last pic).
