We stayed on a beach site in October of 2020 and it wasn’t too crowded - all of the sites are in a line down the beach front but there’s decent space in between each spot and they back up to the dunes. It’s a gorgeous beach front to walk down and it’s decently isolated from developed areas of grand isle. There is a picnic table at each spot and we hid our food container underneath it, however we didn’t secure it enough and animals got into it over the night. There is no cover or respite from the sun or sand, and the bathroom is near the parking lot. Perfect time of year because the nights were cool , however you can’t avoid an early wake up with the sun and heat in the morning.
