As others have said, a great place to see the Golden Gate and do an overnight. Attention to those coming from the north, the first passage underneath, at the end of the bridge, is only 11.10" (the CAMARADAHOME has 12'10" did not pass). I was instructed by the security guards to make a U-turn right after the tunnel, taking the right and heading back. It's well marked and the GPS recognizes this second option.
