Learn more about Kealakekua Bay and the dive operators that service it.

While Kealakekua Bay offers exceptional diving experiences, it’s important to be aware of a few potential drawbacks. Access to the bay is restricted to a limited number of permitted boat operators, meaning booking tours well in advance is crucial, especially during peak tourist seasons. Limited parking at land-based access points can also be a challenge. Additionally, while the bay itself is sheltered, strong currents can be present outside of the bay, a factor to consider for less experienced divers. The bay’s popularity can also lead to crowding, particularly during peak seasons. Visiting early in the morning is recommended to enjoy the best conditions and avoid large crowds.

To make the most of your big island scuba diving adventure in Kealakekua Bay, consider these tips: book your tour well in advance with reputable operators like Fair Wind Cruises, Kona Boys, or Big Island Divers; arrive early in the morning for optimal visibility and fewer crowds; and remember to use reef-safe sunscreen to protect the delicate ecosystem. Kayaking to the site offers a unique and eco-friendly alternative to boat tours, providing a more intimate experience of the bay’s natural beauty. For adventurous scuba divers seeking unique underwater experiences, Kealakekua Bay’s combination of pristine reefs, abundant marine life, and historical significance makes it a true gem of the Big Island and an essential destination for anyone seeking an unforgettable big island scuba diving experience.

Whether you are a marine life enthusiast, an underwater photographer, or simply an adventure traveler looking for a unique coastal experience, Kealakekua Bay deserves a prominent place on your Big Island itinerary.

2. Manta Ray Night Dive

The Manta Ray Night Dive is arguably the most iconic and sought-after diving experience on the Big Island, and a must-do for any scuba enthusiast visiting Hawaii. This unique nighttime adventure, primarily taking place off the Kona coast, allows divers to witness the graceful ballet of manta rays feeding in their natural habitat. Big island scuba diving reaches its peak with this breathtaking encounter.

How it works is remarkably simple yet effective. Powerful dive lights, positioned on the ocean floor, attract plankton, a primary food source for manta rays. These gentle giants, with wingspans reaching up to 20 feet, then glide effortlessly through the illuminated water, performing acrobatic loops and barrel rolls as they feast on the microscopic organisms. Divers kneel on the sandy bottom, mere feet away, observing this spectacular natural phenomenon unfold. Multiple established manta ray dive sites exist along the Kona coast, offering diverse underwater landscapes and ensuring a high probability of manta encounters.

Garden Eel Cove, considered the original manta site, is a popular choice, while Manta Village serves as an excellent backup location. Regularly, divers report sightings of 8-12 individual mantas per dive, making for an unforgettable experience. You can learn more about Manta Ray Night Dive.

Successful implementation of this dive relies heavily on experienced operators. Reputable companies like Kona Honu Divers, Manta Ray Dives of Hawaii, Big Island Divers, and Jack's Diving Locker have popularized and refined the Manta Ray Night Dive, ensuring both diver safety and minimal disruption to the manta rays’ natural feeding behaviors. These operators adhere to strict guidelines designed to protect these magnificent creatures and their environment.

Here’s a quick reference summarizing the key facts about the Manta Ray Night Dive:

As you can see, the infographic highlights the remarkable 95% success rate of manta ray encounters, the relatively shallow dive depth of 30-40 feet, and the average number of mantas seen per dive (8-12), showcasing why this experience is so exceptional.

So, when and why should you choose the Manta Ray Night Dive? This dive is perfect for anyone fascinated by marine life and seeking a truly unique underwater experience. It’s suitable for certified night divers, and those without this certification can often participate under the direct supervision of an instructor. The experience is available year-round, adding to its appeal. However, keep in mind that it is weather dependent and can be canceled due to unfavorable conditions.

Here are some actionable tips to maximize your Manta Ray Night Dive experience:

Get Certified: If you don't have a night diving certification, consider completing a specialty course before your trip. This will enhance your comfort and safety during the dive.
Light it Up: Bring or rent a powerful underwater light, as this will not only improve your visibility but also contribute to attracting plankton and the mantas.
Stay Put: Once on the bottom, remain still and let the mantas come to you. Avoid chasing or touching the rays, allowing them to feed undisturbed.
Choose Wisely: Book your dive with a reputable operator that follows established manta ray guidelines. This ensures responsible and sustainable interaction with these gentle giants.
Test the Waters: If you’re apprehensive about night diving, consider trying the snorkel version of the manta ray experience first. This allows you to witness the magic from the surface before taking the plunge.

While the Manta Ray Night Dive offers an incredible opportunity to encounter these magnificent creatures, it's important to be aware of the potential downsides. The dive is typically more expensive than regular daytime dives, and the popularity of the experience can lead to crowded dive sites with multiple operators present. It can also be overwhelming for new divers, particularly those with limited night diving experience. Despite these potential drawbacks, the near-guaranteed manta ray sightings and the unforgettable nature of the encounter make this a truly exceptional aspect of big island scuba diving.

3. Blackwater Diving

Big Island scuba diving offers a wealth of diverse experiences, but few are as captivating and otherworldly as blackwater diving. This advanced open-ocean night diving technique plunges you into the inky depths, far from the familiar comforts of the reef, to witness the largest migration on Earth: the nightly vertical migration of deep-sea creatures towards the surface. As darkness envelops the ocean, a hidden world awakens, and creatures rarely seen by human eyes ascend from the abyss to feed under the cover of night. The Big Island's dramatically steep underwater topography, dropping off quickly into deep water just offshore, creates the perfect environment for this phenomenon, making it a world-renowned blackwater diving destination.

Blackwater dives typically take place in water depths of 60-100+ feet, well beyond recreational diving limits. Divers are tethered to a downline, a weighted rope extending from the boat to the desired depth, which acts as a reference point in the vast darkness. Powerful dive lights illuminate the water column, attracting a mesmerizing array of pelagic species, many of which are bioluminescent, creating an ethereal spectacle of flashing lights and otherworldly forms. This unique environment offers a rare glimpse into the deep-sea ecosystem and the incredible biodiversity it supports. You might witness larval fish in their bizarre, often transparent, juvenile forms, pulsating jellyfish of all shapes and sizes, or the mesmerizing dance of squid. Even more extraordinary encounters, such as those with paper nautilus, are possible. These delicate cephalopods are rarely seen, making a blackwater dive a truly exceptional opportunity. Learn more about Blackwater Diving

The benefits of blackwater diving on the Big Island are numerous. It's a world-class location for this specialized diving, offering an unparalleled opportunity to see rarely encountered deep-sea species. The experience is also incredibly educational, providing valuable insights into ocean ecosystems and the vertical migration phenomenon. Furthermore, the dark backdrop of the open ocean creates stunning photographic opportunities, particularly for macro photography enthusiasts eager to capture the intricate details of these fascinating creatures. Small group sizes, often limited to just a few divers per guide, ensure a personalized and immersive experience.

However, blackwater diving is not without its challenges. It requires advanced diving skills and experience, including excellent buoyancy control and comfort in deep, dark water. Weather and ocean conditions are critical for a safe and enjoyable dive, and dives may be cancelled due to unfavorable conditions. It’s also an expensive specialty dive, and only a limited number of operators on the Big Island offer this service. The disorienting nature of the dark open water can also be challenging for some divers.

For those considering a blackwater dive, preparation is key. Gain significant night diving experience before attempting this advanced dive, and practice buoyancy control extensively to avoid disturbing the delicate creatures and maintain a safe depth. Bringing a macro lens for your underwater camera is highly recommended to capture the incredible detail of these tiny creatures. Following the guide's instructions precisely is crucial for safety and maximizing your experience. Finally, remember to stay calm if you feel disoriented by the dark water. Focus on your breathing, maintain your position on the downline, and trust your guide.

Big Island scuba diving offers many unique adventures, but blackwater diving stands out as a truly exceptional and unforgettable experience. This specialized dive opens a window into a hidden world, offering a glimpse into the mysterious depths and the fascinating creatures that call it home. For adventurous divers seeking a truly unique underwater encounter, blackwater diving on the Big Island is an experience not to be missed. It offers a blend of thrill, education, and wonder that will stay with you long after you resurface.

4. Cathedral Caves (Cathedrals I & II)

The Cathedral Caves, located off the Kona coast of the Big Island, are a truly exceptional dive site, offering a unique underwater experience unlike any other. These two caverns, aptly named Cathedral I and Cathedral II, are formed by ancient lava flows, resulting in dramatic swim-through tunnels and expansive chambers. The defining feature, and the namesake of these caves, is the way sunlight filters through openings in the lava rock ceiling. These beams of light create an ethereal, cathedral-like atmosphere, illuminating the interior and highlighting the vibrant marine life within. This interplay of light and shadow makes for a breathtakingly beautiful and unforgettable big island scuba diving experience.

The Cathedral Caves are more than just visually stunning. The lava tubes and caverns create a fascinating underwater landscape ripe for exploration. Multiple entry and exit points add to the sense of adventure and allow divers to navigate through the interconnected chambers. These geological formations provide shelter for a diverse array of marine life, offering divers the opportunity to observe reef fish, invertebrates, and occasionally even larger pelagic species seeking refuge. The protected environment inside the caverns also often offers respite from currents, making for a more relaxed and enjoyable dive.

Cathedral Caves provide a unique geological diving experience that caters to a range of experience levels. While suitable for intermediate divers, even experienced divers will find the formations captivating. The multiple swim-through opportunities, unique geological formations, and dramatic light filtering make for spectacular photographic opportunities. Imagine capturing images of classic cathedral ceiling openings with light rays piercing through the darkness, illuminating large caverns with multiple chambers and schools of fish using the caverns for shelter.

However, diving the Cathedral Caves requires careful consideration and preparation. Good buoyancy control is essential to avoid disturbing the silty bottom and impacting visibility. It’s an overhead environment, so divers need to be aware of the associated risks and maintain situational awareness. The enclosed nature of the caverns can be challenging for divers who experience claustrophobia. Careful navigation is also crucial, especially within the interconnected chambers.

Before attempting this dive, perfect your buoyancy skills and ensure you have powerful dive lights, with backup light sources as a precaution. Following your guide closely is crucial, as they are familiar with the layout of the caverns and can ensure a safe and enjoyable experience. Practicing a frog kick or modified flutter kick will minimize the chances of stirring up the silt and reducing visibility.

The popularity of Cathedral Caves as a premier big island scuba diving destination is largely due to the efforts of local Kona dive operators like Big Island Divers and Torpedo Tours. They have recognized the unique appeal of this site and made it accessible to divers seeking an unforgettable underwater adventure. This dive site truly deserves its place on any Big Island diving itinerary, offering an unforgettable blend of geological wonder and marine life encounters. Whether you're an experienced diver seeking a new challenge, an underwater photographer looking for dramatic shots, or simply a curious explorer wanting to witness the beauty of the underwater world, the Cathedral Caves offer an experience you won’t soon forget.

5. Turtle Cleaning Station at Turtle Pinnacle: A Must-Dive for Big Island Scuba Diving

Turtle Pinnacle earns its spot on any Big Island scuba diving itinerary for one compelling reason: it offers virtually guaranteed encounters with Hawaiian green sea turtles (honu) in their natural environment. This seamount, located off the Kona coast, acts as a vital cleaning station, providing a unique opportunity to witness the fascinating symbiotic relationship between turtles and cleaner fish. If you're a diver seeking an intimate wildlife experience, Turtle Pinnacle is an absolute must-see.

Turtle Pinnacle is a submerged volcanic peak rising from the depths, creating a rich and diverse ecosystem. This pinnacle structure provides a perfect habitat for various marine life, including the honu, which rely on the cleaning services offered by smaller reef fish. The pinnacle's topography, combined with the clear, warm waters typical of the Kona coast, creates ideal conditions for observation and underwater photography.

How the Cleaning Station Works:

The cleaning station dynamic is a fascinating display of mutualism. Turtles, often covered in algae, parasites, and dead skin, congregate at specific locations like Turtle Pinnacle. Here, cleaner fish, including yellow tangs, butterflyfish, and wrasses, set up shop. The turtles patiently wait their turn, often adopting specific postures to signal their willingness to be cleaned. The cleaner fish then diligently remove the unwanted hitchhikers, receiving a nutritious meal in return. This interaction benefits both species, creating a harmonious balance within the ecosystem.

Examples of Turtle Pinnacle Encounters:

You can expect to witness the quintessential cleaning process firsthand at Turtle Pinnacle. Green sea turtles, sometimes even multiple individuals, will be present, allowing for close observation of their interactions with the vibrant cleaner fish. You might see a large honu resting motionless on the seabed while yellow tangs meticulously pick at its shell and flippers. Occasionally, other turtle species might also visit the pinnacle, adding to the diversity of the experience. Observing these cleaning symbiosis behaviors provides a captivating insight into the interconnectedness of marine life.

Tips for Diving Turtle Pinnacle:

To maximize your experience and minimize your impact on the environment, consider the following tips:

Respectful Distance: Maintain a safe and respectful distance from the turtles and allow them to approach you if they choose. Avoid touching or chasing them.
Slow and Steady: Move slowly and deliberately in the water to avoid startling the turtles or disrupting the cleaning process. Sudden movements can cause the turtles to swim away.
Observe, Don't Interfere: Resist the temptation to touch or interact with the turtles or cleaner fish. Simply observe and appreciate the natural behavior unfolding before you.
Macro Photography: Bring an underwater camera with macro capabilities to capture the intricate details of the cleaning process and the vibrant colors of the reef fish.
Follow Guidelines: Adhere to all marine life interaction guidelines provided by your dive operator. This ensures the well-being of the turtles and the preservation of the ecosystem.

Practice deep diving skills beforehand: A refresher dive at a similar depth is recommended to ensure comfort and proficiency before exploring the wreck.
Respect the wreck as a historical artifact: Avoid touching or disturbing the wreck to preserve its historical integrity and ecological balance.

The Corsair F4U plane wreck dive offers a truly unique experience for qualified big island scuba diving enthusiasts. It combines the thrill of exploring a historic artifact with the wonder of observing a vibrant marine ecosystem. However, it's crucial to remember that this is an advanced dive requiring proper planning, training, and respect for the site's historical and ecological significance.

7. Puako Reef System: A Shore Diver's Paradise

The Big Island of Hawai'i offers a plethora of scuba diving opportunities, and for those who appreciate the simplicity and accessibility of shore diving, the Puako Reef System stands out as a true gem. Stretching along the South Kohala coast, Puako boasts one of the most extensive and healthy coral reef ecosystems on the island, making it a must-dive location for any underwater enthusiast seeking vibrant coral gardens and a diverse array of marine life. This remarkable reef system truly earns its place on this list of top Big Island scuba diving spots due to its unique combination of accessibility, biodiversity, and sheer beauty.

This thriving ecosystem offers a captivating underwater experience for divers of all levels and interests, from macro photography enthusiasts to those simply seeking to immerse themselves in the beauty of the underwater world.

However, like any dive site, Puako has its considerations. The rocky entry points require careful navigation, especially during periods of surge. Wearing protective footwear is highly recommended. Surf conditions can sometimes affect visibility and make entry and exit challenging, so always check the forecast before heading out. While generally calm, currents can occasionally be stronger than expected, particularly around points and during tidal changes. Finally, be prepared to carry your gear from your parking spot to the entry point, which can be a short walk depending on where you choose to enter the water.
