Discover thrilling manta ray night dives, explore lava tubes and vibrant coral gardens, and encounter diverse marine life. Whether you're seeking the thrill of blackwater diving or the tranquility of Kealakekua Bay, this guide provides the insights you need for an epic underwater experience.

1. Manta Ray Night Dive at Kona

The Manta Ray Night Dive off the Kona coast is widely considered one of the world's most captivating big island scuba diving experiences. This extraordinary encounter allows divers to witness the graceful ballet of Pacific manta rays as they feed on plankton attracted by specialized underwater lights. Divers kneel on the sandy bottom, observing these gentle giants, with wingspans reaching up to 20 feet, glide effortlessly overhead in a mesmerizing display. The experience is truly unique and unforgettable, cementing its place as a must-do for anyone interested in big island scuba diving.

This unique big island scuba diving experience works by utilizing powerful underwater lights placed near the ocean floor. These lights attract plankton, a primary food source for manta rays. Drawn by this abundant food supply, the mantas congregate in these illuminated areas, creating a breathtaking spectacle for divers. As the mantas perform acrobatic maneuvers to filter the plankton, divers have a front-row seat to observe their feeding behavior up close.

Several designated dive sites off the Kona coast, including Manta Village and Manta Heaven, are known for their consistent manta ray activity. The dive typically takes place in relatively shallow waters, ranging from 35-40 feet, making it accessible to divers of all certification levels, from beginners to advanced. The unique lighting system implemented by dive operators plays a crucial role in attracting the plankton, enhancing the likelihood of manta ray encounters.

Manta Ray Advocates, a prominent conservation and research organization, has documented over 300 individual manta rays in Kona waters, highlighting the area's significance as a vital habitat. The dive's popularity is further evidenced by its frequent features in National Geographic documentaries and its consistent ranking as the #1 dive experience in Hawaii by diving magazines. Kona Honu Divers, a pioneer in the manta ray night dive experience, along with other established operators like Big Island Divers, contribute to the accessibility and professionalism of this remarkable big island scuba diving adventure.

Pros:

• Virtually guaranteed manta ray sightings with a 90% success rate.

Tips for an Enhanced Experience:

• Book in advance: Reservations are essential, especially during peak season (December-April).
• Bring an underwater light: While the main lights attract plankton, a personal dive light can enhance your view of the mantas and their intricate markings.
• Remain calm and still: Avoid sudden movements or touching the mantas to ensure their comfort and maintain a respectful distance.
• Consider a sunset/night dive combo: Extend your manta ray encounter by combining a sunset dive with the night dive.

When and Why to Choose this Dive:

The Manta Ray Night Dive is ideal for anyone fascinated by these majestic creatures. It’s a perfect choice for big island scuba diving enthusiasts of all skill levels, including beginners who want a truly memorable first open water dive. Whether you're a seasoned diver or a novice, witnessing the graceful dance of manta rays under the Hawaiian night sky is an experience that will stay with you forever.

This dive isn’t just a thrilling adventure; it’s also an opportunity to learn about these gentle giants and contribute to their conservation by supporting responsible dive operators.

2. Blackwater Diving off Kona Coast

Big Island scuba diving offers an array of incredible experiences, but few are as otherworldly as blackwater diving off the Kona Coast. This advanced diving technique takes you into the pelagic zone – the vast, open ocean – at night, suspending you over thousands of feet of water to witness the largest animal migration on Earth: the vertical migration. As the sun sets, countless creatures rise from the inky depths to feed in the shallower waters, creating a breathtaking spectacle of bizarre and beautiful pelagic life rarely seen by human eyes.

Blackwater dives typically occur in depths of 40-60 feet, but below you lies an abyss of over 2,000 feet. Divers are tethered to the boat for safety in the open ocean, and specialized downlines with powerful lights are used to attract the deep-sea creatures. This creates an ethereal, almost alien landscape illuminated by the dive lights, drawing in a mesmerizing array of larval fish, siphonophores, cephalopods, and other rarely seen organisms. This truly unique experience amongst Big Island scuba diving options is certainly not for the faint of heart.

The Kona Coast of Hawaii is a particularly renowned location for blackwater diving due to its deep offshore waters and the abundance of pelagic life. This cutting-edge diving technique was actually pioneered in Hawaii by individuals like Jeff Milisen, and operators such as Kona Honu Divers are now leading the way in offering these specialized excursions. The success of blackwater diving in revealing the hidden biodiversity of the deep ocean has even been showcased in documentaries like Blue Planet II, highlighting the discovery of new species and capturing stunning footage of these elusive creatures.

For underwater photographers, blackwater diving presents incredible macro photography opportunities. The darkness of the open ocean provides a dramatic backdrop for capturing the intricate details and bioluminescent displays of these unique creatures. However, it's important to note that this type of diving is not for beginners. It requires advanced diving skills and certification, as well as comfort in open ocean conditions. The motion of the boat and the vastness of the surrounding water can induce seasickness, and dives are often weather-dependent, leading to frequent cancellations. The limited availability of operators offering this specialized type of Big Island scuba diving also contributes to its exclusivity.

If you’re an adventurous scuba diver looking for a truly unforgettable experience in Big Island scuba diving, blackwater diving offers an unmatched opportunity to encounter the mysteries of the deep. However, be prepared for the challenges. Taking seasickness medication before the dive is highly recommended, and bringing macro photography equipment is essential for capturing the best results. Practicing neutral buoyancy skills beforehand is crucial for maintaining stability in the open ocean, and booking with experienced blackwater operators is paramount for a safe and rewarding dive.

Here’s a summary of the pros and cons of blackwater diving:

Pros:

• Unique opportunity to see deep-sea creatures.
• Incredible macro photography opportunities.
• Small group experiences with expert guides.
• Cutting-edge diving technique pioneered in Hawaii.

Cons:

• Requires advanced diving skills and certification.
• Can cause motion sickness in open ocean conditions.
• Weather dependent with frequent cancellations.
• Limited operators offering this specialized diving.

Despite the challenges, the rewards of blackwater diving are immense. The opportunity to witness the mesmerizing dance of deep-sea life, to photograph creatures rarely seen by human eyes, and to be a part of a pioneering diving experience makes it a truly unforgettable adventure in the realm of Big Island scuba diving.

This dive site is perfect for a variety of divers, from novice beginners seeking scuba certification and dive courses to experienced divers searching for unique underwater topography.

The site's defining feature is the interplay between volcanic activity and the ocean.

While Richardson's boasts a distinctive underwater landscape, potential divers should be aware of certain limitations. Visibility can be less than ideal compared to sites on the west coast of the Big Island, and the water temperatures on the east side are generally cooler. Rain and runoff can also impact visibility and water conditions. While the site does host marine life, it offers less diversity compared to coral reef environments found elsewhere on the island.

For a successful dive at Richardson's, consider these tips: check recent weather conditions before heading out, and pack a thicker wetsuit to combat the cooler east side water temperatures.
