Keauhou Bay Beach Park in Kailua-Kona, HI

The video captures an underwater scene at night, illuminated by a blue light, featuring a manta ray swimming gracefully. It then shifts to a brief view of two people lying down inside a boat's hull, also lit by the same blue light. The scene returns to the underwater view with another manta ray swimming across the screen multiple times, gliding over rocks near the ocean floor. The video ends with a manta ray moving slowly towards the right side of the frame before disappearing behind a rock formation.
