1. Manta Ray Night Dive – Kona Coast
Big Island scuba diving offers an array of incredible experiences, but few can rival the magic of a manta ray night dive off the Kona Coast. This world-renowned dive is consistently ranked among the most spectacular underwater encounters on Earth, attracting divers of all levels who seek a truly unforgettable wildlife experience. The unique setting and the gentle giants that grace it create a breathtaking ballet of nature that leaves a lasting impression on all who witness it.
The dive itself is relatively simple, making it accessible to divers of varying experience levels. Divers kneel or lie on the sandy bottom in relatively shallow water (30-40 feet), equipped with dive lights. These lights attract plankton, the manta rays' primary food source. As the plankton gather in the illuminated area, so do the majestic manta rays, often with wingspans reaching up to an impressive 20 feet. They glide gracefully through the water, performing acrobatic loops and barrel rolls as they feast on the microscopic organisms. This creates a mesmerizing spectacle, with the divers becoming front-row spectators to this incredible natural phenomenon.
Several designated manta ray dive sites exist along the Kona Coast, including the popular Manta Village and Manta Heaven. These locations have become known for their consistent manta ray sightings, boasting a remarkable 90%+ success rate year-round. This reliability makes the Kona Coast the world's most dependable location for encountering these gentle giants, further solidifying its place as a premier big island scuba diving destination. Manta Village, in particular, often hosts 10-15 manta rays at a time, providing a truly immersive experience. Some individual mantas have even been identified and named by researchers, adding a personal touch to these encounters. The consistent presence of these magnificent creatures has also attracted the attention of National Geographic film crews, who have featured the Kona Coast manta ray night dive in numerous documentaries.
The shallow depth of the dive (30-40 feet) makes it suitable for divers of all certification levels, from Open Water Divers to experienced technical divers. While experienced divers will appreciate the unique wildlife encounter, beginners can comfortably participate, knowing they are in a controlled and relatively shallow environment. Multiple dive operators offer trips daily, providing ample opportunity to experience this incredible dive. However, this popularity can also lead to crowded dive sites, especially during peak season (December-April). Booking in advance is highly recommended to secure your spot.
While the manta ray night dive is undoubtedly one of the highlights of big island scuba diving, it's important to be aware of the potential drawbacks. The cost is typically higher than other dives ($100-150 per dive) due to the specialized nature of the experience. Furthermore, night diving requires additional certification or close supervision from a dive professional. Weather conditions can also impact the dives, with winter swells occasionally leading to cancellations.
For those considering this incredible experience, a few tips can enhance your enjoyment: book well in advance, especially during peak season; bring or rent a good quality underwater light; remain calm and stationary on the bottom to avoid disturbing the manta rays; and most importantly, refrain from touching or chasing these gentle creatures. Consider taking the night diving specialty course beforehand to gain more confidence and familiarity with night diving procedures.
The manta ray night dive off the Kona Coast is a must-do for any diver visiting the Big Island. It offers a unique opportunity to witness these magnificent creatures up close in their natural habitat. This unforgettable experience truly embodies the magic of big island scuba diving and justifies its place at the top of any diver’s bucket list.

These sites offer a truly unique experience, showcasing Hawaii's dramatic volcanic underwater topography.
Cathedrals I & II are characterized by their dramatic swim-through caverns and arches, reminiscent of grand gothic cathedrals.

This site is better suited for more experienced divers comfortable with overhead environments.
Both sites are teeming with life. The rich coral growth provides shelter for a diverse array of tropical fish, while eels and rays often glide through the shadows.

3. Black Water Diving – Kona Coast
Big Island scuba diving offers an array of incredible experiences, but few are as unique and otherworldly as black water diving off the Kona Coast. This specialized diving technique plunges you into the inky blackness of the deep ocean at night, offering a front-row seat to one of the planet's most spectacular natural phenomena: the daily vertical migration. Imagine descending into over 2000 feet of water, tethered to a boat, surrounded by the twinkling lights of your fellow divers, and witnessing the bizarre and beautiful creatures of the deep as they ascend to shallower waters under the cover of darkness. This is black water diving.
Black water diving isn't your typical reef dive. It involves a specialized setup and approach. Divers are tethered to the boat using a downline, providing a point of reference and safety in the vast open ocean. Specialized lighting systems, including powerful dive lights and even blue lights that attract bioluminescent creatures, are essential for illuminating the darkness and attracting the deep-sea inhabitants. The boat’s lights also attract plankton, which in turn attracts the creatures from the depths. As these deep-sea residents, many of which are larval stages of familiar fish and invertebrates, rise to feed near the surface, divers are treated to a breathtaking display of rarely-seen marine life.
This unique big island scuba diving adventure offers unparalleled opportunities to encounter creatures that most people only see in documentaries. Sightings often include delicate paper nautilus, flying fish larvae with their elongated fins, and a myriad of mesmerizing deep-sea jellies pulsating with ethereal light. Kona is one of just a handful of locations globally where this type of diving is readily available, making it a true bucket-list experience for adventurous divers. Learn more about Black Water Diving – Kona Coast to understand the unique appeal of this experience.
This experience also contributes to scientific research. Marine biologists often utilize black water dives to study these elusive deep-sea creatures, gaining valuable insights into their behavior, distribution, and the overall health of the deep-sea ecosystem. The photographs and observations made during these dives can provide invaluable data for ongoing research projects.
While the allure of black water diving is undeniable, it's crucial to understand the requirements and challenges. This type of diving is not for beginners. It requires an advanced open water certification, as well as a degree of comfort in open ocean conditions. The experience can be more expensive than traditional dives, typically ranging from $200-300 per dive, due to the specialized equipment and expertise required. The open ocean conditions can also lead to motion sickness for some divers.
For those considering this extraordinary big island scuba diving experience, here are some essential tips:
- Certification and Experience: Ensure you have at least an advanced open water certification and are comfortable diving in open water at night.
- Motion Sickness: Take motion sickness medication beforehand if you are prone to seasickness.
- Photography: Bring macro photography equipment to capture the intricate details of these fascinating creatures.
- Operator Selection: Book with experienced black water dive operators only. They will have the necessary expertise, equipment, and safety procedures in place.
- Buoyancy Control: Practice your neutral buoyancy skills extensively beforehand. Maintaining proper buoyancy is crucial for avoiding contact with other divers and the delicate deep-sea creatures.
Kona Honu Divers are considered pioneers of black water diving on the Big Island and have helped popularize this extraordinary experience. The work of marine biologist Jeff Milisen and underwater photographers like Steven Kovacs, alongside research conducted by organizations like National Geographic, has further showcased the incredible biodiversity encountered during these dives.
