Beautiful place and lots to see and learn about. But make sure you bring your bugs pray or it could be a really bad experience for the kiddies.
Tours offered on Fri-Sat-Sun. But, a ranger on site will answer all questions and caretakers cottage is open on these days to view if you miss the tour. Friday in April almost had Key to ourselves.
Yes, there is a composting "comfort station" here unlike Indian Key!
If you bring munchies, keep them with you. Just saw a raccoon eyeing my backpack in my kayak!
