Driving Directions to Owl Canyon (Use "69 South Hill Drive, Brisbane, CA 94005" for navigation system)

1) From Bayshore Blvd, turn onto Valley Drive, the entrance to Crocker Industrial Park in Brisbane.

2) Drive down Valley Drive and turn left at the stoplight at the intersection of Valley Drive and South Hill Drive

3) Drive a very short distance on South Hill Drive; as the road begins to curve, immediately after a pedestrian crosswalk, you'll see a steep driveway on your left with potholes. Turn into that steep driveway and drive up. 

4) Immediately at the top of the driveway turn right and continue driving down the road for two minutes. The trailhead entrance to Owl Canyon is at the base of a small water catchment basin turned skate park, as shown on this map: https://goo.gl/maps/8mGYsgN5eSL2
