Great Beachside Park
What a lovely beach! I had a great time visiting last summer. There's a $5 entrance fee per person for day use. They also offer camping for both RV's ($20/night) and tents ($10/night).
We got there pretty early in the day, and were able to secure one of the little hut/gazebo things for our belongings. If you see one of them available, grab it! It's nice to have a shady spot to retreat to. The beach was very clean, and much less crowded than I was expecting.
There are porta potties and outdoor showers by the beach, and indoor facilities closer to the road.
