I thought I replied to this las tnight but something must have happened to my post.
We did the Turtle/Shipwreck cove excursion last June. It was great to be able to swim with the sea turtles. There is something very tranquil about being in the water and having them swimming around your. The shipwreck cove part of the tour is ok. The ship wreck is really an old steam tugboat but its in shallow enough water that you can dive down to it if you wish. There were lots of fish there. The beach at shipwreck cove was outstanding. The finest white sand I have ever seen. Almost like flour. I would recommend this tour again. I can not say anything about the others.
