There is no food for sale or anything to buy to eat on this island.
Unless you can eat grass like the horses, either you Bring Your Own Lunch (BYOL) or you go without.
There are plenty of picnic tables so you can eat whatever you bring in comfort. After we finished our tour, we came back to the dock and I lay on one of the picnic table benches and looked up at the Spanish moss and took a little nap
Favorite Dish: We picked up box lunches from our hotel, and they were very good. They included a club sandwich, chips, cheese crackers (Bob doesn't eat cheese, so I ate it), cookies, an apple (which Bob also didn't eat), and water.
You cook your own at a campsite that you reserve through the National Park Service.
If you leave your breakfast unguarded while visiting the bathroom, don't be surprised if the tame deer comes and eats your oatmeal.
Favorite Dish: Freeze dried Mandarin Orange Chicken!
