The bridge is 1.7 miles long. So figure twice that if you’re going to walk both ways on it.
The first time I did that, it was a fabulously bright clear day and there was a sailboat regatta on the bay. There must have been at least a hundred, or several hundred, sailboats out there.
There is a parking lot at the south end of the bridge, accessible from 101 northbound as you approach the bridge, and also from the surface street (is it Lincoln Blvd?) that follows the coastline south from there. This is the parking lot of which Shalmanese writes “there’s extremely limited parking”. GFL finding a place to park there.
There is also a smallish visitor center of sorts right there. Also, Fort Point, a Civil War era fort, is right there.
At the NORTH end of the bridge there is another place to park (also accessible from northbound 101) – a vista point with a visitor center of sorts, always crowded with Japanese tour buses and people taking pictures. If you get to the Alexander offramp (the road to Sausalito), you’ve just missed it. It’s not precisely at the end of the bridge, but a short distance north of that. I DON’T know, offhand, if you can walk back to the bridge from there. Check it out. You might find a place to park there. Maybe.
For a SPECTACULAR view of the bridge, do this: As you drive north across the bridge, notice that mountain ahead on the left, overlooking the mouth of the bay. Take that Alexander offramp. At the bottom of the ramp, turn LEFT and go under the highway, then turn LEFT again. This just takes you right to an on-ramp right back into San Francisco, BUT… Immediately where that on-ramp is, there’s a road to the right that goes up that mountain. Take that. This area is called Fort Cronkhite.
There are ruins of some WWII-era fortifications at various places along that road. There are various places to pull over and park. There’s a trail down the mountain to a small beach in a cove below. And, weather permitting, the view of the bay, the bridge, and S.F. is spectacular – just like if you were flying over in an airplane.
At the very top of the mountain is another fortification that was supposed to be a HUGE gun emplacement, only the war ended before it was completed. There are also hiking trails in the area.
