What are nice romantic getaways around San Francisco for a journey of three days?

I heard Napa Valley and Big Sur are special places for example, but such are the specific areas to see and discover in these places? What about Point Reyes? Muir Woods …. PS: This is my first wedding anniversary

Point Reyes or even Mendocino area is beautiful hiking, biking, kayaking, massage, meditation, etc.-also have some fun places to eat in the small little city nearby .. but is rather a drive like 2 hours away …. Or off the coast overnite stay in Half Moon Bay, walk along the beach of the Carlton Ritz (hang out and watch the sunset), shop on Main St, massage, horseback riding, hiking, go golfing … The next day south on Hwy 1-head in Santa Cruz, do the walk, walk along the beach, lunch or dinner in Capitola, etc. .. Of course, this beach town sometimes get foggy though we are with heat waves for navigation because invertion of time …
