October and September are the best times of the year to be in San Francisco. Colombus Day is a huge celebration with an additional boost of Fleet Week and The Blue Angels Air Show overhead.
Bike alongside the Bay from Fisherman's Wharf to Sausalito and then take the Ferry to Angel Island. Spend some time in Tinburon. Head over to the Marin Headlands and Point Bonita Light house. Spend the day at Chrissy Field. There is so much to do! Let me know if you want even more ideas that are more consistent with what you are looking for... Like sea kayaking in Sausalito or taking the 49mile drive to see all of San Francisco's tourist and scenic areas. Point Reyes and Olema are beautiful and rich with migration wild-life.
