1. Experience the World-Famous Manta Ray Night Dive
No guide to Kona diving would be complete without featuring its most iconic attraction: the manta ray night dive. Consistently rated one of the best night dives in the world, this is a truly once-in-a-lifetime encounter. The experience is like an underwater ballet, where you get a front-row seat to one of nature's most majestic spectacles.
How It Works
Dive operators have established specific, well-lit feeding sites. After sunset, powerful lights are placed on the ocean floor, attracting massive blooms of phytoplankton, the primary food source for manta rays. Certified divers descend to the sandy bottom, often around 30-40 feet, and gather around this "campfire" of light.
As the plankton concentrates, giant manta rays, with wingspans that can exceed 15 feet, swoop in to feed. They glide, barrel roll, and soar just inches above your head, gracefully scooping up the plankton. It's a non-intrusive, responsible interaction, as you are simply an observer in their natural feeding environment.
Why It's a Must-Do
This isn't just a dive; it's a profound connection with marine life. The sheer size and grace of the mantas are awe-inspiring, creating a serene yet exhilarating experience you will never forget. For many, this specific dive is the primary reason they choose Kona diving for their vacation. Reputable operators like Kona Honu Divers specialize in making this adventure safe, educational, and magical.
2. Explore the Pristine Kealakekua Bay
Protected as a Marine Life Conservation District, Kealakekua Bay is a jewel of the Kona coast, offering some of the most vibrant and pristine underwater ecosystems in Hawaii. Renowned for its exceptional water clarity and historical significance as the landing site of Captain Cook, the bay is a sanctuary for marine life. It provides a sheltered environment perfect for both novice and experienced divers.
How It Works
Access to the bay's prime dive spots is best achieved by boat, which helps preserve the delicate coastline. Dive tours typically anchor in the calm, protected waters near the Captain Cook monument. Divers can explore a steep, dramatic drop-off adorned with sprawling coral gardens, home to an incredible density of tropical fish. The bay's protected status means the reef is exceptionally healthy and teeming with life.
Spinner dolphins are also frequent visitors to the bay, often seen resting and playing in the mornings. Diving here means following strict conservation guidelines, such as using reef-safe sunscreen and maintaining a respectful distance from marine animals, ensuring the sanctuary remains pristine for generations to come.
Why It's a Must-Do
Kealakekua Bay offers a different kind of Kona diving experience: it's a serene immersion into a thriving, protected reef system. The sheer abundance of fish, the clarity of the water, and the stunning coral formations make for unforgettable underwater photography. This dive is less about a single-species spectacle and more about appreciating the biodiversity of a healthy Hawaiian reef. Companies offering specialized diving tours can guide you through this underwater paradise, providing context on its history and ecology.

4. Dive with an Award-Winning, Conservation-Focused Operator
Choosing the right dive operator can define your entire underwater experience, and Kona Honu Divers stands out for its commitment to small groups, marine education, and personalized service. This boutique operation specializes in creating intimate and memorable underwater adventures, making it a top choice for divers who value quality over quantity and have a passion for marine conservation.
How It Works
Kona Honu Divers focuses on providing a premium experience by keeping their dive groups small. This ensures every diver gets personalized attention from their guide, whether they are a new diver feeling a bit nervous or an experienced photographer looking for the perfect shot. Their charters explore a wide range of Kona's best dive sites, with a special emphasis on turtle encounters and unique volcanic geology.
Their operation is deeply rooted in eco-consciousness. The crew provides detailed briefings not just on the dive plan but on local marine life, their behaviors, and how to interact with them respectfully. This educational approach enhances the dive, turning it from a simple sightseeing trip into a meaningful conservation experience.
Why It's a Must-Do
If you want to feel like a valued guest rather than just another number on a boat, this is the operator for you.

The emphasis on education means you’ll leave with a deeper appreciation for the Kona diving ecosystem. Their dedication has earned them consistent recognition, as highlighted in articles about them being voted the best dive operator in Kona.
5. Venture into the Abyss on a Blackwater Dive
For the truly adventurous, blackwater diving is one of the most unique and surreal experiences Kona diving has to offer. This highly specialized night dive takes you miles offshore, where you descend into the deep ocean over thousands of feet of water. You'll witness one of the planet's largest migrations as bizarre, alien-like creatures rise from the abyss to feed near the surface under the cover of darkness.
How It Works
Unlike a reef dive, a blackwater dive is a mid-water drift dive. Divers are connected via tethers to a large float on the surface, which is equipped with powerful down-facing lights. This setup drifts with the current, attracting a stunning variety of pelagic and larval-stage creatures that are rarely, if ever, seen in shallower waters. You’ll be suspended in the inky blackness, watching a living light show of bioluminescent organisms and otherworldly critters float by.
Why It's a Must-Do
This dive is less about big animals and more about discovering the weird and wonderful macro life of the deep. It’s a chance to see creatures that look like they belong on another planet, from translucent larval fish to vibrant cephalopods. The experience has been featured in major nature documentaries and is a favorite among underwater photographers and marine biologists for the incredible biodiversity it reveals. This is an advanced dive, perfect for experienced divers looking for the ultimate Kona adventure. Ready to take the plunge? Kona Honu Divers offers expert-led blackwater night dives for those certified and prepared for the challenge.

This experience blends the excitement of personal propulsion with the beauty of marine sightseeing, making it an excellent option for snorkelers, non-divers, and anyone seeking a novel way to interact with the ocean. It's an accessible thrill ride through a vibrant aquatic paradise.
How It Works
These tours equip you with a high-performance, eco-friendly underwater scooter. After a thorough safety and operations briefing, you'll enter the water and learn to pilot your Seabob. The scooter does all the work, pulling you effortlessly on the surface or allowing you to dive down for short periods to get closer to marine life. You can glide alongside sea turtles, explore shallow reefs, and cover far more distance than you could with fins alone, all under the guidance of an expert.
Why It's a Must-Do
This tour is a perfect middle ground between snorkeling and scuba, offering a dynamic perspective on Kona diving environments without the need for certification. It's a fantastic activity for families and mixed groups with varying comfort levels in the water. The sheer fun of zipping through the clear blue ocean like a dolphin is an unforgettable experience.
