3. Black Water Diving (Pelagic Night Diving)

For truly adventurous scuba divers seeking a unique and otherworldly experience, black water diving off the Kona coast of the Big Island offers an unparalleled glimpse into the mysteries of the deep sea. This specialized type of night diving, also known as pelagic night diving, takes you far offshore, suspending you in the inky blackness above depths exceeding 6,000 feet. Here, you’ll witness the largest daily migration on Earth: the vertical migration of deep-sea creatures that ascend to the surface waters under the cover of darkness. This makes black water diving one of the most exceptional forms of big island scuba diving.

So, how does it work? Under the guidance of highly experienced dive operators, small groups of divers are transported miles offshore into the open ocean. Unlike traditional anchored dives, black water diving utilizes a specialized tethered diving system. Divers are connected to a downline, a rope extending from the boat, which provides a point of reference in the vast, dark expanse. Powerful lights are suspended from the boat, attracting a dazzling array of rarely seen deep-sea creatures. As these organisms rise from the abyss, they are drawn to the illuminated area, creating an ethereal spectacle for divers to observe.

This unique environment allows for close encounters with bizarre and beautiful creatures rarely, if ever, seen by human eyes. From bioluminescent jellyfish and pulsating siphonophores to larval fish with fantastical shapes and colors, the diversity of life encountered on a black water dive is truly astounding. It's not uncommon to witness strange larval forms of familiar fish, offering a glimpse into their early life stages. The deep black backdrop also enhances the vibrant displays of bioluminescence, turning the ocean into a living light show.

Pioneered by operators like Kona Honu Divers, black water diving has gained international recognition, featured in stunning National Geographic photography and award-winning underwater photography exhibitions.

4. Cathedral Caves (Cathedrals I & II)

The Cathedral Caves, located off the South Kona coast of the Big Island, are a truly remarkable dive site. These underwater lava tubes, known as Cathedrals I and II, offer a unique glimpse into the island’s volcanic past. The formations create dramatic swim-through caverns, aptly named for their resemblance to grand cathedrals. Light filters through cracks in the lava rock ceiling, illuminating the interior and creating an ethereal atmosphere. This interplay of light and shadow, combined with the unique geological formations, provides a truly unforgettable big island scuba diving experience.

The caves themselves are ancient lava tubes, formed when the outer surface of a lava flow cooled and solidified while the molten lava inside continued to flow. Over time, the flowing lava emptied out, leaving behind these hollow tubes. The ocean eventually eroded through the outer rock, revealing these fascinating underwater caverns. The depths within the caves range from 25-60 feet, making them accessible to advanced divers. Inside, divers can explore intricate swim-through passages and expansive chambers, marveling at the unique geological formations and the abundant marine life that has made these caves their home.

This specialized training will equip divers with the necessary skills and knowledge to safely navigate overhead environments. Always carry both primary and backup underwater lights, and dive with experienced local guides who are familiar with the specific nuances of these sites. Checking the surge and swell conditions before diving is essential, as is practicing buoyancy control in controlled environments before venturing into the caves.

The Cathedral Caves hold a well-deserved spot on any big island scuba diving itinerary. They offer a unique and challenging experience that will undoubtedly leave a lasting impression. However, remember to prioritize safety and ensure you have the necessary skills and training before embarking on this incredible underwater adventure.
