How do you get to that residential beach near diamond head?

I remember going to a beach near or in Diamond head where you drive through a residential area, and along these big homes, there is like this little alley that leads to a quite and calm beach in the back of the homes. The alley is soo small you can almost past it if you dont pay too much attention. Does anyone know how to get there, its been so long....|||i think i know what you're talking about. its a beautiful beach, but i'm not sure exactly how to get to it. sorry.
