Turtle Canyon is da spot to see turtles. The cleaning station will result in a couple to a butt load of Hawaiian Sea Turtles. There are several other shipwrecks or shallow reefs off Honolulu that will have a napping turtle to be found. I have dove with Kaimana Divers and they are a top notch scuba company. They own their own boat, so they can ensure that you will visit one of the many turtle sites found off the south shore.
