Posted the details, forgot the broad brush strokes:

It is at the Hyde Street Pier, 2905 Hyde st., at Jefferson st., Fisherman's Wharf. There are about 5 or 6 bus lines that go near. ...You can also call the ranger office at (415) 556-6435 for more info. The sing starts at 8, with the gate opening at 730. I'll put you on the gatelist (it's done by reservation, though it's free)... .
