Slip Into the Crystal Clear Waters and Scuba Dive Kona, Hawaii on Jack’s Diving Locker’s Classic 2 tank boat diving trip. When you scuba dive in Kona, you soar through schools of tropical fish, swim through lava rock arches, or visit green sea turtles resting on the reef. Divers often see dolphins ride the bow wake on the way to the dive site or humpback whales hanging out on the surface during the winter season.
