Dive-site story
Situated along the rugged limestone coastline of Onna Village in Okinawa, this site centers on a semi-submerged sea cavern. Sunlight filters through the underwater opening and reflects off the pale seafloor, illuminating the cavern chamber in saturated cobalt blue. Outside the cavern mouth, hard coral formations drop along a terraced reef wall toward sand flats where macro critters hide.
Luminous natural blue backlighting inside the primary cavern chamber
Dense schools of sweeping cave fish hovering in the shadows
Expansive coral terrace and drop-off immediately outside the cave mouth

Seasonality
