Burnett is through out to Twin Peaks Blvd. but with no sidewalks along part of it. Twin Peaks Blvd. in the park could also use at least one sidewalk. There are always people walking, jogging, and bicycling here.
From the Blvd. headed downhill a short distance to say hello to Tank Hill Park (a north shoulder of Twin Peaks), just past Mountain Spring (steep, curvy street to the left, pic 6; through to Midtown Terrace), and up the shorter Tank stairs (pic 7) from Clarendon/Twin Peaks Blvd. Tank Hill Park (pic 8) is accessed by stairways only. The west stairs are steeper, down to Belgrave. West a few blocks on Belgrave from here are trailheads for Mount Sutro's Interior Greenbelt Park.
Continued to the Pemberton steps from Tank. Along Clarendon and Twin Peaks Blvd. vehicles speed around Tank Hill way too fast. I've always been nervous even crossing at the crosswalk here; yet another place we pedestrians could use speed bumps and skyways. Once across, over to the vehicle dead-end of Crown Terrace to the top of Pemberton Place (211 steps: pic 9), first down its older flight (pics 10, 11, 12), then the longer, newer part (pics 13, 14, 15).
Another scary area for walkers to try to cross is at the foot of Pemberton and Clayton. A skywalk here would be nice to continue the steps from Pemberton through the short Clayton/Corbett garden stairs (36 or so).
