Everyone must do this at least once. It's one of the most iconic bridges in the world. Looks great in any kind of weather. Beware, for it is very popular and there will be many others walking along side you. Keep an hear out for anytime you hear the bridge being closed down, because they often keep it open to visitors. I went with the bridge closed down once and it was wonderful to experience the majestic bridge without the rumblings of the traffic.
We walked the bridge during its 75th anniversary year: http://www.goldengatebridge75.org/. It’s just an awesome walk. It opened May 27th, 1937 and has a fascinating history. Joseph B. Strauss headed up the project and learned a lot about bridges during the $35M and four years it took to build. He dedicated the bridge with a poem:
“At last the mighty task is done; Resplendent in the western sun The Bridge looms mountain high; Its titan piers grip ocean floor, Its great steel arms link shore with shore, Its towers pierce the sky.”

Driving from the city, make sure you take the last right turn just before you reach the toll booth area. Good parking lot, visitor center and bridge access is here. It can be crowded and hard to find a spot, but wait as people come and go constantly. It was a foggy, windy day and gave us the full SF Golden Gate Bridge bucket list experience. Not to miss.
Walking the golden gate bridge is a highlight of any trip to San Francisco. I have only walked it a handful of times and I have lived here my entire life. It can be pretty windy on the bridge, so wear a jacket or wind breaker.
The views of the Marin headlands are great and you can see Angel Island, Alcatraz, and the entire skyline of downtown SF.
