is "Old Coast Road", about 30-45 minutes south of Monterey on Hwy 1. It's kinda hard to describe how to find, but here's a good Google map
that should show the way. It starts just on the north side of a big bridge
, and then continues for about 7 miles before dumping back out onto Hwy 1 again further South.
I don't know any other good trails in the SF Bay Area, if you find any please let me know!
