But we did camp along the beach on the island.

I've stayed here on two separate occasions both with larger groups of people. There's plenty of real estate and no need to worry about being on top of one another. There are limited facilities (a few vault toilets and a covered pavilion). You can seek shelter indoors at the Light Keepers quarters during the high season (regular business hours) if needed. There are several boardwalks that meander around the island and numerous sandy paths connecting the sound side to the ocean side.

There is a large raccoon population on the island so store your food and water accordingly. We did experience a raccoon running off with a dry bag full go food that wasn't secured to a permanent structure. It can be buggy if there's not much wind, but generally there is a breeze blowing across the island.

If you don't have your own personal water craft to get to the island, you can take a private ferry to the island. There are several companies that offer reasonably priced tickets to and from the island.

Again, this isn't a review for the cabins here per se, but relevant in that there is more camping available.
