Where is a really romantic secluded beach within 100 miles of monterey california?

I'm trying to find a really nice beach to take my girlfriend to next week and I was just looking for a few ideas as to which beach I should take her. Pfeiffer beach in Big Sur is great, but I'd like to take her somewhere we haven't been before. so yeah anywhere within 100 miles of the Monterey peninsula. We'll be there around sunset. Preferably nice soft sand and not rocky painful sand lol. thank you!
