I'm staying in SF for three nights before driving in a fairly leisurely fashion down to Beverly Hills, where my brother lives, so I'll detour to see interesting places to the south then. "shortish" means perhaps an hour or two.
On your way down south, take Skyline Boulevard (Hwy 35), then Hwy 84 or 9 to Hwy 1. Drive down the coast on Hwy 1, stopping as you wish at Moss Landing, Pt. Lobos (find Edward Weston's tripod holes), Garrapata Beach (Find Morley Baer's tripod holes), Pfeiffer Big Sur, Cambria, etc. Join 101 at San Luis Obispo and take that to the 405. South on that to Mulholland (if you want to go in to BH the back way), or Sunset.
