The NP camping area at Minnie Water is nice, right on the beach, basic facilities. Broom's head is also very nice, right on the beach as well. We had some gear stolen from there, so be careful, and Urunga is a nice spot as well. The caravan park in Urunga is right in town. I think my pick would be Brooms head if looking for a caravan park (pretty simple though), for more bush camping head to Minnie Water in the National Park. All top spots though in my opinion. We have only been there out of season, so don't know what they are like with crowds.
