Most visitors never leave the porch, which is a shame, because the island is more interesting than the lunch.
A short nature trail loops away from the buildings through gumbo limbo, cabbage palm and sea grape, with interpretive markers in places. It takes twenty minutes at a stroll and is the only way to appreciate how much height the shell mound actually gives you.
The shoreline is mangrove rather than beach, so this is not a swimming stop. The undeveloped beaches nearby on the outer islands are, and boat operators often pair the two.
Gopher tortoises live on the higher ground. Ospreys nest on the channel markers. Dolphins work the sound and are commonly seen on the crossing in both directions, which is why several operators sell the trip as a wildlife cruise with lunch attached rather than the other way round.
Insects are present in the interior at dawn and dusk. In the middle of the day, when the boats come, they are not much of an issue.
Take your rubbish back with you. Everything that arrives on this island leaves by boat, including what you brought.
