emerges from an underwater cave exit into open water, the limestone karst archway framing a sudden expanse of blue beyond the passage. This marks the second stage of a swim-through at The Cathedral, a submerged cave system where divers transition from relative darkness into daylight within metres. The rock, encrusted with sponges and coralline algae, marks the boundary between cavern and open reef. 4K, vertical wide shot, cave diving POV, scuba diver POV.
