The Parks website has a reasonable website that will help you find where you can and can't camp. I have attached two links below, one is an interactive map, you can zoom in and out, until you find the area you are looking for.
The second link is a hyperlink from the map, it tells you what you can and can't do on the island, how to go about booking etc.
