Can I setup a Tent and camp at the dunes?

Yes there's a spot just for that

Yes you can. But not right in the dunes there's a camping area just between the beach and dunes. You might need 4x4 on the sand. Don't forget to air down.

Yes, thats what this place is..

Yes u can

Yep.

Thanks for the quick reply! How can I tell where the designated area is located? Is there signs?
