What’s the best campsite for a couple with a tent... looking for spacious, shaded, close to beach... thanks!

Huntington beach would be a great fit. Clean, bathouses & a very short walk to the beach. They have a designated area for "primitive camping" as well as for campers & motor coaches. There is easy access to grocery stores & dining, as well as grill pits. Drinks & snacks are available @ the commissary. Have fun, we did. Oh, it is extremely quiet.

This link should help. I love it there. Clean bathrooms and real close to the beach.
