We spend much of our summer going to Southern California beaches. My favorite by far is Crystal Cove. It is a State Beach in a State Park. It is just the most beautiful, least crowded beach here (imo). It is just north of Laguna Beach and south of Newport Beach. Corona Del Mar is nice too, but can be more crowded. Coronado Beach (San Diego) is great, near the famous Hotel Del Coronado. In the L.A. area, Santa Monica has a lot of energy and is fun, also near Venice Beach, but I don't feel it is that nice of a beach. If we go there, it is for the atmosphere, not the beach day experience. Also, in LA, Manhattan Beach in the South Bay has a nice Southern California feel to it. I love our beaches! Plan to pay about 15 to park at most beaches here.
