As I mentioned earlier, I was lucky enough to get some directions to a great place to park for free if you decide to walk across the Golden Gate Bridge. Not only is the free part good, but you get to enjoy this very beautiful and scenic walk overlooking the cliffs by the bridge. To get here, just keep going straight (don't pull into the National Recreational Area... or if coming from there, make a right at the exit instead of a left to go back to town) when heading towards the bridge. You are going to go under an underpass and veer left then quickly to the right. Shortly after that little maneuver, you'll see a dirt pullout on the right. That's your spot! Just park and walk towards the cliff. You'll see where you need to walk from there... (hint: it's to the right). Once you get to the bridge, you will first have to walk under it using the ped/bike path.
