San Onofre State Beach In Southern California. $15.00 to get in unless you have a yearly pass. 6 paths down to the beach. Path 1 & 6 are dog beaches. Path 1 is the best. Path 6 has to many rocks and make it difficult to walk. I have spent many days down on this beach(trail 1) with Jackson off leash and seldom see more than a few surfers & occasionally another dog or two. It's beautiful and a private.
