I've lived in the OC for most of my life. Believe it or not I have only been to 5 beaches at the most in the entire time!
Laguna Main Beach
Doheny State Beach
Salt Creek State Beach
I decided to spend this summer checking out what I've been missing.
Tip: Buy a park pass. For 40.00 you can get into all the state parks/beaches. These visits can add up fast at 5.00 bucks a pop.
3 Arch Bay
Huntington State Beach
Corona Del Mar
