The spot offers year-round diving access, making it a flexible choice for visiting divers. Twelve documented species observations provide a baseline for understanding local marine biodiversity. Community-contributed videos give prospective divers a visual preview of conditions and wildlife they might encounter.

  • 3 minutes and 34 seconds is a long time to hold your breath, but add in the oxygen used to swim that depth and its truly an amazing achievement.

  • 120 m depth is almost thirteen (13) atmospheres of pressure – you experience one atmosphere of pressure increase for every 10.06 m (33 ft) of depth in water. That's deeper than most recreational dives (<100 m). An incredible feat indeed. 👏
