Dive operators take a group of people to a designated dive location. This is the easiest way to dive that I know of. It requires very little physical exertion. The dive boat picks you up when you're finished diving. Coral heads are as large as small houses, with many swim-throughs and caves.
Colorful fish are abundant, as are moray eels and small stingrays.
If you're really lucky you might see an octopus on a night dive. Fish varieties include blue tang, silver tarpon, angelfish, parrotfish, silversides and many more. Water temperatures vary between 82-87 degrees. Chancanab Underwater Park is a great place to dive or snorkel because it is fairly shallow. Workers at the park frequently feed the fish tortillas which brings the fish to shore quite often for viewing.
