We picked up our hire car (you definitely don't need one for San Fransisco) and headed off towards Hwy 1 down the scenic coast, including 17 Mile Drive at Monterey, where you'll find the Lone Cypress.
Monterey was our final destination for that day and we checked out the Monterey Bay Aquarium, where I think they have the neatest jelly fish display.
