This is the top diving spot in the world for drift diving. 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.
