Lots of them.
Walk across the golden gate. Beautiful views of the city. Drive across the golden gate, pull off and look at the city.
Downtown, there are many places, Lombard street, Coit tower go up to the top and take photos, Fishermans wharf, ride the cable cars, the hills and valleys, to mention a few.
Go to treasure island, check to see if you can get on. I went to school there, long time ago, Navy. I had my car, a VW bug with stick. Had to use the emergency brake couple of times at a stop light!
Nice car chase in the movie Bullitt with Steve McQueen in San Francisco.
How long of a stay?
