Picture this: you're weightless, floating through crystal-clear water. Sunlight streams down through an ancient lava tube, illuminating the path ahead as a massive Hawaiian green sea turtle glides effortlessly past you. This isn't a scene from a documentary; it's just another day of Hawaii scuba diving, and the Kona coast on the Big Island is where it all happens.
Kona is a protected paradise, a diver's dream with mind-blowing visibility, dives that are famous the world over, and marine life you simply won't find anywhere else.
Why Kona Is The Epicenter Of Hawaii Scuba Diving
You can find good diving across the entire Hawaiian archipelago, but the Kona coast is truly in a league of its own. The secret is in the geography. The enormous volcanoes of Mauna Loa and Hualalai create a massive natural shield, blocking the powerful trade winds that batter other parts of the islands.
This protection results in exceptionally calm and clear water all year long. It’s what makes scuba diving the Big Island such a reliable and breathtaking spot for everyone from brand-new divers to seasoned pros. Visibility often pushes past 100 feet, revealing a dramatic underwater world carved out by ancient lava flows.
What you get is a thriving, dynamic ecosystem. On any given dive, you might be exploring:
- Intricate Lava Tubes: Imagine swimming through huge underwater caverns and archways formed by volcanic eruptions from long ago.
- Sprawling Coral Gardens: We have incredibly healthy hard coral reefs, home to a kaleidoscope of tropical fish.
- Dramatic Drop-Offs: There's nothing quite like gliding along an underwater cliff that plummets into the deep blue, attracting larger pelagic species.
A Hub for Marine Encounters
Kona isn't just known for its beautiful scenery; it's world-renowned for consistent, up-close encounters with incredible marine life. This is the home of the Manta Ray Night Dive—a true bucket-list experience where gentle giants swoop and barrel-roll just inches from your face as they feed on plankton.
Having reliable access to a spectacle like that is what puts Kona on the map as a premier global dive destination. In fact, the state as a whole is a diving hotspot, with over 1.5 million scuba dives happening annually across more than 215 licensed shops. The Big Island is a major player in that, drawing people from all over the world who want to see our lava tubes, reefs, and, of course, our mesmerizing night dives. You can discover more about Hawaii's incredible diving scene to see just how special it is.
The sheer variety and consistency of Kona's underwater world make it an unforgettable place to dive. To truly understand why it's a top-tier destination, here’s a quick breakdown:
Why Kona Is a Top-Tier Scuba Diving Destination

Here at Kona Honu Divers, our entire team is dedicated to showing you these natural wonders safely and responsibly. We don't just work here—we live and breathe Kona diving, and our passion is sharing this incredible world with you. From your very first breath underwater to advanced technical diving, we're here to make every trip a memory that lasts a lifetime.
Exploring Kona’s Most Unforgettable Dive Sites
While you'd be hard-pressed to find a bad dive along the Kona coast, some spots are truly legendary. These are the places that divers talk about for years, the ones that deliver those once-in-a-lifetime marine encounters that define a trip to the Big Island.
The island’s volcanic past has carved out a spectacular underwater world. Imagine exploring dramatic lava tubes and massive archways, their shadowy interiors teeming with schools of fish seeking refuge. We also have famous "turtle cleaning stations," where Hawaiian green sea turtles (honu) patiently line up for smaller fish to give them a spa day, nibbling away algae and parasites.
But as incredible as these dives are, there's one experience that puts Kona on the world's scuba diving map.
The World-Famous Manta Ray Night Dive
This isn't just a dive; it's a front-row seat to an underwater ballet performed by gentle giants. As the sun dips below the horizon, we descend to a sandy spot on the ocean floor and set up powerful lights. These lights act like a dinner bell, attracting clouds of plankton—the manta rays' favorite meal.
What happens next is pure magic. Giant manta rays, some with wingspans stretching over 12 feet, emerge from the darkness. They glide, swoop, and perform graceful somersaults right over your head, their huge mouths open to filter the plankton-rich water. It's a humbling, mesmerizing, and utterly unforgettable spectacle.
While a few spots host this amazing encounter, not all are created equal. We've found that one particular site consistently delivers the best experience.
Why Garden Eel Cove Is The Premier Manta Location
For the ultimate Manta Ray Night Dive, we always take our divers to Garden Eel Cove. Known to locals as "Manta Heaven," it provides a more intimate and reliable encounter for a few key reasons:
- A Naturally Sheltered Spot: The cove is protected from the open ocean swell, which means a calmer, safer, and more comfortable dive, especially after dark.
- An Ideal Viewing Area: The seafloor at Garden Eel Cove forms a natural amphitheater. This allows divers to settle in on the sand and get an unobstructed, upward-facing view of the mantas dancing in the lights above.
- Vibrant Nearby Reefs: The site is right next to a thriving coral reef. This makes the first dive of our two-tank trip a beautiful dusk exploration of the reef before the main event begins.
Choosing the right spot is everything for this bucket-list dive. The protected nature of Garden Eel Cove creates the best possible interaction for both the mantas and the divers, making the whole experience safer and more magical.
The Mysterious Kona Blackwater Dive
If you're looking for a completely different kind of thrill—one that feels more like a trip to another planet—then you have to try the Kona Blackwater Dive. Forget the reef; this is an expedition into the abyss.
We head miles offshore where the ocean floor is thousands of feet below. Here, you'll be tethered to the boat, drifting in the deep, dark water as we shine powerful lights into the void. This light draws in some of the ocean’s most bizarre and rarely-seen creatures as they make their nightly journey from the depths to feed near the surface.
You’ll see things that look like they're straight out of a sci-fi film: glowing jellies, translucent larval fish, and alien-like squid. No two dives are ever the same, and you never know what strange, beautiful life form will materialize out of the darkness. It’s a true adventure into a hidden universe.
These are just a couple of the world-class experiences that make Hawaii scuba diving so special. To see what else is out there, check out our full list of the top Big Island scuba diving sites.
At Kona Honu Divers, we live to share these unforgettable moments with our guests. Our expert guides are here to make sure every dive is safe, respectful to our marine life, and absolutely incredible.
Matching Your Skill Level to the Perfect Dive Trip
One of the best things about Hawaii scuba diving, especially here in Kona, is that there’s a perfect trip for just about everyone. It doesn't matter if you're just curious about taking your first breath underwater or you're a seasoned pro with hundreds of dives logged—the Big Island’s coastline has an adventure waiting for you. Let's find your perfect match.
If you're new to diving or maybe just a little rusty, Kona’s calm, clear reefs are the ideal classroom. A beginner-friendly reef tour is the perfect way to get comfortable and see the incredible underwater world without the pressure of a more demanding dive.
Getting Started the Right Way
For anyone ready to take the full plunge, earning your Open Water certification is the ticket to a lifetime of adventure. When you learn with a top-rated operator like Kona Honu Divers, you’re not just getting a certification card; you're building a foundation of safety, confidence, and respect for the ocean. Our experienced instructors are with you every step of the way.
Once you’re certified, a whole new world opens up. The next logical step is to join one of our classic Kona diving tours. These trips will take you to some absolutely spectacular sites, showing off the best of Kona's volcanic underwater landscapes and thriving reefs.
Advanced Opportunities for Experienced Divers
For certified divers with a bit more experience under their weight belts, Kona serves up challenges that are as rewarding as they are thrilling. The underwater topography here is a playground for more experienced diving opportunities, from deep pinnacles that rocket up from the seafloor to dramatic volcanic walls that plummet into the blue.
Many of these sites feature currents, making them perfect for drift diving. This is where you just relax and let the ocean carry you along the reef, an almost effortless way to cover a lot of ground and see more marine life. It’s a huge draw for divers. The U.S. diving tourism market is expected to hit USD 1,101.6 million by 2025, and drift diving is projected to capture 25% of that market as divers seek out these incredible, scenic experiences. You can read more about the growing trends in U.S. dive tourism to see how Hawaii is helping to lead the charge.
To explore these amazing environments safely, we run a dedicated premium advanced dive trip that takes small groups of experienced divers to our most spectacular and challenging sites.
Diving Fun for the Whole Family
What if your group has a mix of divers, snorkelers, and maybe someone who just wants to enjoy a day on the boat? That's where a trip with Kona Honu Divers really shines. Our spacious boats are designed to keep everyone comfortable and happy.
While the certified divers in the family are off exploring the deeper parts of the reef, snorkelers can be having a blast in the vibrant shallow coral gardens right from the surface. Everyone gets to share in the beauty of Kona’s marine life, making it a perfect family day out.
For the ultimate personalized experience, nothing beats a private charter. This gives your group exclusive use of the boat and crew, so you can completely customize the day. You pick the dive sites, decide how long to stay at each one, and create a schedule that fits your family's pace. It’s the absolute best way to create an unforgettable day of Hawaii scuba diving.
Don’t just take our word for it. Here’s what fellow divers have to say about their experiences with us:
Essential Gear And Preparation For Your Hawaii Dive
A truly great Hawaii scuba diving trip starts well before you step onto the boat. A little smart preparation means you'll spend every second underwater soaking in the sights, not wrestling with leaky gear or feeling a chill. The good news is, getting ready is simple.
Even with our famously warm waters, having the right exposure suit is the key to staying comfortable from the beginning of your dive to the end. Water temps in Kona hover between a beautiful 75-82°F (24-28°C) all year long. For most people, a 3mm or 5mm full wetsuit strikes the perfect balance between warmth and flexibility.
Beyond the wetsuit, a few small personal items can make a world of difference.
Your Personal Dive Kit Checklist
While you can always rent a full setup, many divers find that bringing a few key pieces of their own gear makes the experience much more enjoyable. There's nothing quite like the confidence of using a mask you know fits your face perfectly.
Here's a quick list of essentials worth packing:
- Mask and Snorkel: If you have one you love, bring it! A good, comfortable seal is priceless.
- Dive Computer: It’s a critical piece of safety gear, and using your own means you already know its menus and alerts inside and out.
- Reef-Safe Sunscreen: This is a big one. Standard sunscreens contain chemicals that are devastating to our fragile coral. Always look for mineral-based options with zinc oxide or titanium dioxide.
- Rash Guard: Perfect for sun protection on the boat between dives and adds a nice extra layer of warmth under your wetsuit.
- Reusable Water Bottle: Help us protect these incredible islands from single-use plastic waste while staying hydrated.
The Advantage Of High-Quality Rental Gear
Let's be honest, lugging a full set of scuba equipment through an airport is a hassle. That’s where relying on professional, top-tier rental gear changes the game. At Kona Honu Divers, we don't just hand out used equipment—we take its maintenance and performance personally.
Our rental equipment isn't an afterthought; it's central to our promise of a safe, incredible dive experience. Every BCD, regulator, and wetsuit is meticulously inspected and serviced to the highest industry standards, ensuring it performs flawlessly when you need it most.
Traveling light without sacrificing quality or safety lets you focus on what you came here for: the magic of Hawaii scuba diving.
Unlock Longer Dives With Enriched Air Nitrox
Ever wish you had just a few more minutes to explore that amazing lava tube or hang out with a turtle? Enriched Air Nitrox can give you that. In simple terms, Nitrox is just a breathing gas mix that has a bit more oxygen and a bit less nitrogen than the regular air you’re breathing now.
That seemingly small change has huge benefits. When you absorb less nitrogen, your body is under less stress, which can significantly extend your no-decompression limits. That means more bottom time on your dives. As a bonus, many divers report feeling much less tired after a full day of diving on Nitrox.
Because we want you to have the absolute best experience possible, Kona Honu Divers offers free Nitrox for all certified Enriched Air divers on our Kona diving tours. It’s one of our favorite ways to help you get the most out of every single minute underwater.
Hawaii’s Unique Marine Life And How To Protect It
Diving in Hawaii is like stepping into a different world, a living museum where a surprising number of the residents exist nowhere else on the planet. The islands are so isolated that life here evolved on its own unique path. That means a huge percentage of the marine life you’ll meet is endemic—you just won't find it anywhere else.
You’ll get to know the locals pretty quickly. Graceful honu (Hawaiian green sea turtles) are everywhere, whether they're resting on the reef or cruising past you in the blue. It's also common to see playful pods of spinner dolphins and countless species of colorful butterflyfish, many of which are unique to Hawaii's waters.
This incredible biodiversity is why Hawaii scuba diving is more popular than ever. In fact, scuba diving tourism worldwide is projected to become an $18.5 billion industry by 2035, and Hawaii’s one-of-a-kind ecosystems are a massive part of that draw. You can see more insights on the global diving market here to understand why places like Kona are becoming true crown jewels for underwater adventurers.
Your Role as a Guardian of the Reef
With all this attention comes a serious responsibility. The vibrant coral reefs and all the creatures calling them home are part of a very delicate balance. As divers, we're just visitors here, and every single thing we do underwater matters. A conservation-first mindset isn't just a nice idea; it’s absolutely essential if we want to protect this paradise for years to come.
This philosophy is at the very heart of how we run our tours at Kona Honu Divers. It’s not just about seeing the amazing marine life; it’s about interacting with it respectfully and ensuring our presence doesn't cause harm.
Practical Tips for Sustainable Diving
Protecting Hawaii’s underwater world is a team effort, and it starts with simple, mindful actions on every single dive. Following these practices ensures the reef stays just as beautiful as you found it.
-
Master Your Buoyancy: This is the golden rule. When you achieve perfect neutral buoyancy, you can float effortlessly over the reef. This prevents you from accidentally kicking or bumping into delicate coral polyps or other marine life.
-
Look, Don’t Touch: This rule applies to everything—coral, fish, turtles, you name it. Never touch, chase, or try to handle any marine animal. Even a light touch can strip the protective mucus layer off a fish or turtle, making them vulnerable to disease.
-
Secure Your Gear: Make sure your gauges, octopus, and camera are clipped snugly to your BCD. Dangling equipment can easily drag across the reef, breaking coral that took hundreds of years to grow. It's a small detail that makes a huge difference.
By keeping these simple guidelines in mind, you become an active partner in ocean conservation. Every dive is a chance to be a protector of this incredible underwater world. For a deeper look at best practices, feel free to learn more about responsible and considerate diver etiquette on our blog.

Your Hawaii Scuba Diving Questions, Answered
Thinking about a dive trip to Hawaii? You’ve probably got a few questions. We get it! To help you get ready for an unforgettable underwater experience, here are the answers to some of the most common things we hear from divers.
What’s The Best Time Of Year To Dive In Hawaii?
Here on the Big Island, the honest answer is: anytime! We're lucky enough to have incredible diving year-round. Our water temperatures are always inviting, hovering around a comfortable 75°F (24°C) in the cooler months and warming up to a lovely 82°F (28°C) in the summer.
The Kona coast is a diver's dream. It’s tucked away in the lee of our massive volcanoes, which shield us from the trade winds and keep the seas exceptionally calm and clear. If you're looking for the absolute flattest conditions, the summer months from May to September are tough to beat. But winter diving, from December to March, has its own unique magic—you can often hear the incredible songs of humpback whales echoing through the water on your dives.
Do I Need An Advanced Certification For The Manta Ray Night Dive?
Not at all! You just need to be an Open Water certified diver to join this world-famous experience. We’ve designed the entire dive to be incredibly safe and accessible for everyone.
With a top-notch operator like Kona Honu Divers, the manta dive is a very controlled, almost serene, experience. We guide you to a designated spot on a sandy bottom, usually in shallow water around 25-35 feet. You simply settle in and watch the show unfold, so there's no need to worry about tricky navigation or fine-tuning your buoyancy. Of course, every dive starts with a detailed safety briefing, and our expert divemasters are right there with you the entire time.
What If My Family Doesn't Scuba Dive?
No problem! Hawaii is the perfect place for groups with mixed interests, and we love welcoming non-divers aboard. Snorkelers can have just as much fun on our boats.
The clear water and shallow reefs mean they'll get a spectacular view of the colorful fish, sea turtles, and coral from the surface. The Manta Ray Night Dive even has a fantastic snorkel option where they can float on top and watch the giant mantas glide just inches beneath them. And when you’re not on the boat, the Big Island offers endless adventures—from exploring Volcanoes National Park to hiking waterfalls or just kicking back on the beach.
Should I Bring My Own Gear Or Rent It?
This is really a matter of personal preference and travel style. Many divers can't imagine a trip without the comfortable, familiar fit of their own mask or the data from their own computer. On the other hand, lugging a full set of dive gear across the country can be a real hassle, not to mention expensive. Before you decide, it’s always wise to figure out whether you need comprehensive trip protection for your dive adventure, which can give you peace of mind about your equipment.
Renting is an easy and popular alternative. At Kona Honu Divers, we offer high-quality, meticulously maintained rental gear that’s serviced well beyond industry standards. A great middle ground many divers take is to pack their "personal" items—like their mask, computer, and maybe fins—and rent the heavier stuff like the BCD and regulators from us.
Your unforgettable underwater journey is just a decision away. Here at Kona Honu Divers, we live to share the safest, most spectacular diving the Big Island has to offer. Book your adventure with us and get ready to discover the magic of Hawaii.
