We decided to hire a guide and are glad we did. For $20 US, plus the $2.50 US park fee each we got; the guide, transportation out to the reef and dives on two sites over a two hour period. I took 1,200 pictures, which I edited down to 77, with these 19 being the most interesting:
Me and son James and his fiancee Maria in and out of the water. Some of the more photogenic beasts in the water.
Brain and Fan Corral.
Peak-a-boo. Where's Waldo?
Corral, with extreme editing.
