My wife and I booked this trip for a Saturday, but it was canceled. I was happy it was canceled since the weather was unusually cold and there was a threat of rain. A word of advice--don't book the tour too far in advance. They are non-refundable and you cannot change the dates. I booked the tickets a week in advance and regretted it once I saw the weather forecast. We had to drive an hour from Miami to find out it was canceled. But the next weekend the weather was perfect. Boca Chita is a tiny key full of campers, but it is very pretty. We were given an hour to explore the island while the boat took the snorkelers to a nearby reef. There's a beautiful lighthouse where you get some amazing views. The water at the key is crystal clear and we saw a stingray and several tropical fish just from walking around. One part of the island has red and black mangroves along a beach full of shells. If you can do this on a beautiful day it is definitely worth a 3 hour tour.
