The best diving spot in Isle of pines is the Gadgi region. Over million of years ago, the land mass was much larger than it is now, sank into the sea. This separated the island from the New Caleodian mainland. The Coral Polyps formed and started building their reefs in the waters between the separation of the land masses. Diving in the region gives evidence for the ancient coral formation.
The next major geological shift happened recently. The landmass of the island rose causing the land expose to the open air. This can be seen in the Gadgi district where fossilized shells are present all over the rocks that are above the sea.
The Gadgi diving spot also has cave structures under the blue waters. It is called the Oupere Grotto. There are narrow walls and soft yellow corals in these diving spots. The wall opens into an underwater cathedral. A narrow opening from the ceiling illuminates the cave. The view is spectacular and mesmerizing!
The spot of Glee Island Drop off is also spectacular for diving.
