Walk the Golden Gate Bridge. It’s an experience. San Francisco is home to one of the most magnificent structures and it would be a shame to not experience it fully. If you start at Crissy Field (you can park in the Marina neighborhoods), just follow the path and signs and you will be eventually led up to the bridge and able to walk over it. Enjoy the absolutely breathtaking views, take pictures and people watch. Just remember to bring a coat as it gets windy, some water, and wear comfortable shoes!
