Check out the redwoods Big Sur, just a short drive north of there across the bridge (the big one, also very cool).
Fisherman's warf. Ride the street cars. Sea lions at Monterey (S of there by a bit). Get a dark green '68 Mustang fastback and play Bullet going down the steep hills

I was there in '75 (a while ago) but today, google it for ideas (places to go, restaurants, etc). That's what I do anytime I travel.
