The path along the bay at Crissy Field is wonderful. The area used to be a marsh, then an air field names after Crissy...and now has a restored wetland, restored low dunes and a nice jog,walk, roll path. Truly wonderful views of the bay and the goldengate bridge and big ships, etc.

Art shows at fort mason are often wonderful. If you go early enough you should be able to park nearby with a placard, but even with a placard , parking in sF can be tough. Look on the event web site or call them to ask about parking. Some parts of fort mason parking are pavement are lumpy with old street car track lumps, but you should be able to navigate. From fort mason i beleive you can wander without you car to the east towards maritime museum...or definitely to the west to crissy field.

More great advice: We used to love to go to the Cliff House for Brunch and then look down on the old Sutro baths. My brother in law had a great poster of "the old days" at the baths.

And there is also a great art museum near there - the Legion of Honor (sort of a Cliff House visit "bonus" http://legionofhonor.famsf.org/ )- as well as great views of the Golden Gate Bridge from over by the cliff side parking.

And don't forget the DeYoung Museum in Golden Gate Park if you like art, plus the nearby Japanese Tea Gardens are beautiful. http://deyoung.famsf.org/

Not sure if on your prior trips you may have seen these places?

And Easyt - it would be fun to watch the fisherman on the pier. They weren't doing that when I was jogging by years ago.

And finally - rtb: Glad you know Oran - and please tell him that at our next high school Reunion in Klamath - the first round is on him, ok? :)

err - what I meant was - you have received more great advice from other posters. :)
