Is this private property?

I’m a huge sucker when it comes to driving on mountain roads and I was wondering if this is a private drive since Google Maps doesn’t go there. This is at Summit Road when Loma Prieta Road splits off. I see some gates with signs but someone I talked to in my DMs says he bikes on Loma Chiquita so IDK
