A huge park with a free for all atmosphere. There are rules, but they're not enforced. Dogs are supposed to be leashed but they weren't always and it wasn't a big deal. If you come with a group, you can circle your rigs and have a somewhat private area. You can't beat the proximity to the beach - the campground is just over some dunes (which block the wind!). Bathrooms were not very clean, but if you're in an RV, it's not a problem. There was quite a bit of manure (bring a pooper scooper) from the grazing cows (and dogs?). I'd go back. We camped here in a Motorhome.
Think Burning man, with families, hundreds of them. There are rules, not enforced, more of a self regulated community. A zoo on weekends, heaven and cows during the week. Yes, most of it is cow pasture, they may be in your site on the weekdays. Dune side camping, some waterfront (tight and real resident feel), mostly fields among the big dunes. 1 mile by several hundred yards wide, pick a spot, setup camp. Or setup a wagon circle with your rigs, bonfires are common all year long. Inside fields tend to be rowdy, with groups of campers, generators, palm tree lights, and loud conversation. Dune side tends to be quieter with Ocean sounds prevalent and more families. A child's paradise for many decades. Small dunes, huge dunes (no ATV), biking, hiking, beach combing (safe surf), and even the occasional snipe hunting ;) Porta-a-potties (better, and emptied often) and dirty restrooms for tenters, RV's use your own. No showers. Water spigots in the center meadow that people 'tee' off of where you can fill up. No power, dump stations, 2. Check-in, daytime. Checkout before nightfall. We camped here in a Travel Trailer.
