A medium-large rock located in the middle of a fairly hilly residential area. Bouldering, sport, and TR climbs exist. The hours of the park are from 9am-sunset, and it is closed to climbing on the third weekend of every month. The rock is sandstone similar to that in the castle rock area. There are a decent variety of routes, ranging from 5.7 to 5.12, plus bouldering up to v6.
Handley Rock park is located in a neighborhood off the Edgewood Rd. exit from 280 near Redwood city. A GPS or very detailed map is almost necessary to navigate the labyrinth of streets nearby. The rock is literally ten feet from the small parking area.
It's too bad that there isn't more info out there on this crag. Here's some of what you need to know:
1 - There's an unfortunate amount of graffiti and trash on the rock
2 - Top rope access is to the left of the rock as you approach from the parking area, before you actually start to go around the monolith
3 - Technically there are sport climbs here, but I wouldn't trust ANY of the bolts if someone paid me
4 - The bolting at the top is really weird. Some super-solid bolts, some spinners, some small rusty bits, and most routes only have a single bolt. I backed everything up, although it was difficult to back up certain routes. (The routes with a single bolt have 3/4" x 6" construction eye bolts, but still... one bolt doesn't do it for me.)
I would offer Handley Rock is a diamond in the rough. It needs to be picked up, for sure!! But, I enjoyed the crack climb to the left of the cave on the South side and the face climb to the right of the cave also.
I understand SheClimbs Bay Area is doing a clean up this Saturday 11/16/13. Way to go SheClimbs!!!
