Beginner-friendly crater reef with turtles.
Koko Craters is a short boat ride from Koko Marina and one of Oahu's easiest crater-style reef dives. The site is a cluster of shallow volcanic bowls with coral ledges and sandy pockets, so it feels simple to navigate while still giving plenty of room for turtles and other reef life. It suits beginners and relaxed boat dives, especially on calm days with clear water.
