4.00Immediately in the harbor we saw 1 turtle for a brief moment which was nothing special, then we proceded past Cameo island to Keri caves for only 20 min of swimming, from there we went to the last stop of swimming to turtle Island for 1 hour and back to harbor, overall I was a bit disappointed. I can't say I got my money's worth. And all of this was just 3 hours from 12 to 15pm.
Wonderful caves and turtles!
