This Underwater Pictures page is dedicated to the beautiful fish and corals in the sea around Grand Cayman.
It sounds unlikely but most of them can be seen by snorkeling with a waterproofed camera surprisingly close to shore, even around George Town.
In fact the farther out and deeper you go, the fewer really colorful fish seem to live there. There are, however, more interesting rock creatures and corals, not to mention bigger fish and rays.
The biggest tarpon we saw are fed each evening from Rackham's pub right in George Town harbor so even a non-swimmer can get good photos by going there.
For non- or weak-swimmers, Grand Cayman has a number of options to get you down to see the underwater world. There are glass-bottom boats, a semi-submersible and a submarine.
Many of these pictures were taken through the window of the Atlantis semi-submersible (as you can see in this photo) and still came out well. If diving makes you nervous but you still want pictures, then the semi-submersible is the way to go. There are more pictures at Underwater Photography
As well as the methods for getting underwater without diving or snorkeling I mentioned above, there's a neat old-fashioned looking divers' helmet, from Sea Trek, that you place over your head to rest on your shoulders. As you WALK into the water, air pressure keeps your head dry and provides air for breathing. It takes some getting used to when you first put it on, and weighs a ton out of the water, but after a few minutes, it's a great way to see the watery world.
One reason I like the diving helmet better than snorkeling is -- I hate putting the breathing tube in my mouth, foolishly squeamish I know but I do.
Bigger and scarier fish, like tarpon, generally are found in deeper water away from the shore so you're not likely to bump into them using the diving helmet, which is good or bad depending on your point-of-view.
