Beneath blue-green water, a sandy route leads through a massive rock arch covered in orange branching coral, purple growths and yellow tube sponges. Swim forward from the diver's first-person perspective, with dark gloves occasionally rising into the lower edge of the view during swimming strokes. After passing under the arch, leave a rusted shipwreck railing on the left and angle gently toward a turquoise-lit opening among rounded boulders. Small fish, rising bubbles and shafts of sunlight surround the route. The cave entrance draws closer, its pointed interior formations becoming clearer, while the diver's body remains out of view.
