Imagine dropping into perfectly clear, turquoise water. Beams of sunlight dance through the surface, lighting up a world of dramatic lava tubes and ancient volcanic arches below. This isn't just any dive spot—this is Kailua-Kona, a world-class scuba destination that consistently serves up incredible visibility and some of the most vibrant marine life you'll find anywhere.
Discovering Kona’s Underwater Paradise
Kailua-Kona isn't just a dot on the map; for divers, it’s a bucket-list destination. Tucked away on the sheltered leeward side of the Big Island, these waters are naturally protected from the powerful trade winds. The result? Exceptionally calm and clear conditions nearly all year long.
This unique geography is the secret sauce behind Kona's legendary visibility, which often stretches beyond 100 feet. It's what allows you to really take in the breathtaking underwater landscapes carved out by volcanoes millennia ago. Think of it as a massive aquatic playground, full of lava tubes, swim-throughs, and towering pinnacles just waiting to be explored. These structures aren’t just cool to look at; they're also home to an incredible variety of marine life, making every single dive a genuine adventure.
What Makes Kona a Premier Dive Destination
Sure, the clear water is a huge draw, but the sheer amount of life here is what really seals the deal. The biodiversity is staggering. On any given dive, you're likely to come face-to-fin with some of the most iconic creatures in the Hawaiian Islands.
A few highlights you can almost always count on:
- Hawaiian Green Sea Turtles: We call them honu, and you’ll see these gentle giants everywhere, either munching on algae or just cruising over the reef like they own the place.
- Abundant Reef Fish: The reefs are a riot of color, with huge schools of bright yellow tangs, intricate butterflyfish, and chubby parrotfish darting all around you.
- Unique Volcanic Formations: The experience of swimming through an ancient lava tube is something you'll never forget. It’s what truly sets kailua kona scuba diving apart from other tropical destinations.
- Iconic Night Dives: Kona is world-famous for what happens after the sun goes down, especially the legendary manta ray night dive—but more on that later!
It’s no surprise this place has become a global hotspot for diving. Since the first shops opened up back in the 1980s, the local industry has grown to support an incredible 100,000 certified scuba dives annually. That’s a powerful testament to the quality of the experience here, drawing over 150,000 dive tourists each year to see it for themselves.
Whether you're about to take your very first breath underwater or you're a seasoned pro with thousands of dives in your logbook, Kona has something special for you. From exploring sun-drenched coral gardens to dancing with gentle giants at night, this slice of paradise is a must for any serious diver.

The Classic 2-Tank Morning Dive
This is the quintessential Kona experience and a perfect introduction to diving on the Big Island. We head out in the morning sun to explore two distinct dive sites, giving you a fantastic tour of the volcanic landscapes and thriving marine life that put this place on the map.
This trip is a great fit for just about everyone. If you’re a newer diver, it’s the perfect way to build confidence. If you’re an old pro, it’s a beautiful, relaxing way to just enjoy the reef. You can expect to drift through colorful coral gardens, explore ancient lava tubes, and see plenty of Hawaiian green sea turtles, moray eels, and massive schools of fish.
The World-Famous Manta Ray Night Dive
If you ask a diver about Kona, the first thing they’ll probably mention is the Manta Ray Night Dive tour. This isn't just another dive; it's a true, once-in-a-lifetime underwater spectacle that has to be seen to be believed.
After the sun sets, we descend to a natural underwater "stage" and use powerful, diver-safe lights to attract plankton. This massive cloud of food draws in the stars of the show: giant manta rays, some with wingspans over 15 feet. You simply kneel on the sand and watch in amazement as these gentle giants swoop, glide, and barrel-roll just inches above your head. It’s a surreal and humbling experience you’ll never forget.
With a success rate that often tops 90%, this is one of the most reliable and spectacular megafauna encounters on the entire planet.
The Mysterious Black Water Night Dive
Ready for something completely different? The Kona Black Water Night Dive is for the truly adventurous soul. This isn’t a reef dive. We motor out over thousands of feet of water, tether you to the boat, and let you drift in the deep, inky blackness of the open ocean.
It sounds intense, and it is—in the best way possible. Your dive light illuminates a universe of strange, bioluminescent creatures that migrate from the abyss toward the surface every single night. You'll see things that look like they're from another planet: larval fish, transparent squid, and otherworldly jellies. It's a dive that feels like you're exploring deep space, perfect for experienced divers looking for a new frontier.
Premium Advanced Dives for Experienced Divers
If you’re an experienced diver wanting to explore beyond the classic sites, our Premium Advanced Dives are built for you. These charters head to Kona’s more challenging and remote locations, where the topography is more dramatic and the potential for big animal encounters is higher.
These dives require an advanced certification, as we often explore deeper walls, remote pinnacles, and sites known to attract pelagic visitors like sharks and different species of rays. This is your chance to see a wilder side of Kona that most divers miss.
If you’re planning on being here for a few days, you can save by bundling trips. Check out our Kona diving packages to make the most of your time in the water with us.
Exploring Kona’s Must-See Dive Sites
Now that you've got a feel for the adventures we offer, let's dive into the legendary sites that truly define Kailua-Kona scuba diving. We're not just talking about spots on a map; we're talking about the unique underwater landscapes that make this coastline one of the best in the world. From intricate lava tubes to dramatic offshore pinnacles, every site tells a story of volcanic creation and the vibrant life that now calls it home.
The Big Island’s fiery origins have created an underwater playground unlike any other. Ancient lava flows sculpted incredible formations—arches, caverns, and swim-throughs that feel completely otherworldly. Dropping into one of these sites is like exploring a submerged cathedral, especially when beams of sunlight cut through openings in the rock. These natural shelters are also magnets for marine life.
The Magic of Garden Eel Cove
When people talk about the world-famous Manta Ray Night Dive, one site consistently comes up as the best of the best: Garden Eel Cove. While a few other spots host this incredible encounter, Garden Eel Cove delivers a superior experience for a few key reasons. Its location within a protected bay shields it from the big open-ocean swells, making for a much calmer and more predictable dive.
The site itself is like a natural amphitheater with a gently sloping sandy bottom, allowing divers to settle in comfortably. We set up our lights in the middle—our "campfire"—creating a perfect viewing area that gives everyone a front-row seat to the mantas' breathtaking feeding ballet. On top of that, the surrounding reef is just healthier and more vibrant, making the entire experience that much more beautiful.
- Protected Location: Tucked inside a cove, it’s a safer and more comfortable spot, which is great for divers of all levels.
- Better Viewing Area: The site's natural layout creates the perfect stage for watching the mantas swoop and feed just inches above your head.
- Healthier Reefs: The coral and fish life around the viewing area are more robust, adding incredible scenery to an already amazing dive.
Lava Tubes and Volcanic Wonders
Beyond the manta dive, Kona is famous for its dramatic volcanic topography. Many of our best dive sites are defined by these ancient lava formations, offering a one-of-a-kind adventure for certified divers.
Sites like "Cathedrals" and "Golden Arches" are known for their massive lava tubes and archways. Swimming through these structures is an unforgettable feeling, as schools of brilliant yellow tangs and butterflyfish dart through the sunbeams piercing the cavern ceilings. These formations also provide a safe haven for shy critters like moray eels, lobsters, and the occasional whitetip reef shark resting on the sandy floor. You can learn more about the unique features of these spots in our guide to Big Island scuba diving sites.
The legendary Kona Manta Ray Night Dive is a true bucket-list adventure, with encounter rates that consistently hit 80-90% at prime locations just a short boat ride from shore. This incredible reliability has made Kailua-Kona an international icon for anyone who loves diving after dark.
Diverse Marine Life Encounters
While the underwater architecture is stunning, it’s the local residents that truly bring these reefs to life. You’ll almost certainly spot graceful Hawaiian green sea turtles (honu) gliding over the coral or napping under a ledge. Schools of colorful fish are a constant, creating a kaleidoscope of movement on every single dive.
And you'll want to keep your eyes peeled for other exciting visitors. It’s not uncommon to see a majestic eagle ray soaring through the blue or a pod of spinner dolphins playing in the boat's wake on the ride out. This rich biodiversity, combined with the spectacular underwater scenery, is exactly why Kona holds its own as a top-tier global diving destination.
Why Kona Honu Divers Is Your Top Choice
Picking the right dive operator in a place like Kailua-Kona is just as important as choosing the right dive site. Your entire experience—your safety, your comfort, your memories—really comes down to the crew, the boat, and their dedication to what they do. That’s where we come in.
At Kona Honu Divers, we’re not just running a business; we’re a crew of passionate divers and ocean lovers dedicated to sharing the magic of Hawaii’s underwater world.

That isn’t just a number; it represents a deep, practical knowledge of Kona's dive sites, an instinct for marine life behavior, and the calm, professional competence to handle any situation that comes up.
We take safety seriously. Period.

A Better Experience on the Water
Your dive adventure is more than just the time you spend underwater. We believe the whole day, from stepping on the boat to cruising back to the harbor, should feel like a first-class experience. That's why we’ve designed our boats with diver comfort as the top priority.
There's nothing quite like surfacing from an amazing dive and stepping into a hot freshwater shower right on the deck. It's one of those small things that makes a huge difference. Our boats also feature:
- Spacious, Shaded Decks: Giving you plenty of room to gear up or just relax out of the sun.
- Smart Gear Storage: Keeps your equipment and personal items organized and secure, not cluttered underfoot.
- Easy Water Entry & Exit: Our custom-built ladders make getting back on board effortless, even with all your gear on.
These details are what elevate a good kailua kona scuba diving trip into a great one. You can learn more about what sets us apart by reading why we’re considered the best dive shop in Kona.
The Little Things That Count
Beyond the big stuff, it's the thoughtful extras that truly define your day with us. We know what divers want because we are divers.
We are one of the only shops in Kona that provides complimentary nitrox for all certified divers. This lets you enjoy longer bottom times and shorter surface intervals—which means more time exploring our incredible reefs.
Plus, you can be confident you’re diving with safe, high-quality gear. Our rental equipment is obsessively maintained and serviced, so you can focus on the turtles and lava tubes, not a foggy mask or a finicky regulator. From start to finish, our goal is simple: to give you the peace of mind that comes from diving with the very best.
Planning Your Ultimate Kona Diving Trip
Okay, now that you’ve got a taste of the incredible underwater world waiting for you, let’s talk logistics. Planning your Kona dive trip should be exciting, not stressful. A little bit of prep goes a long way, ensuring you arrive ready to jump in and make every moment count.
One of the best things about diving here is that it's phenomenal all year round. Thanks to Kona's spot on the leeward side of the Big Island, we're shielded from the major winds and swells, giving us amazing conditions pretty much 365 days a year. It’s a consistency you just don’t find in many other top-tier dive destinations.
That said, different seasons do bring their own special highlights. For a deeper dive into that, check out our guide on the best months to scuba dive in Hawaii.
When to Visit and What to Expect
Kona’s water temperatures are a dream, staying in a comfortable range from 75°F (24°C) in the winter to a bath-like 82°F (28°C) in the late summer. And the visibility? It’s almost always fantastic, often stretching out well beyond 100 feet.
Here’s how the seasons generally feel:
- Summer (May – October): This is when we see the flattest, calmest seas. The boat rides are smooth, the water is glassy, and it’s an absolute paradise for new divers and underwater photographers.
- Winter (December – March): The water might be a few degrees cooler, but the trade-off is pure magic. This is humpback whale season. There's nothing quite like hearing their songs echo through the reef on a dive—it’s an experience that will stay with you forever.
Gearing Up for Comfort and Safety
Even in our warm tropical waters, having the right wetsuit is the key to a happy dive. A good suit keeps you from getting chilled, especially on your second or third dive of the day, so you can just relax and focus on the amazing marine life around you.
We find that a 3mm or 5mm full wetsuit is perfect for Kona. Most people are comfortable in a 3mm, particularly in the summer. But if you know you get cold easily, or you're planning on doing night dives, a 5mm suit is a great call for that extra bit of warmth.
Getting Certified or Brushing Up Your Skills
Never dived before? Or maybe it’s just been a while? We’ve got you covered. We run a full range of PADI courses right here in Kona’s calm, aquarium-like conditions.
- Discover Scuba Diving: This is your ticket to the underwater world if you’re not certified. We'll teach you the basics and then take you on a genuine ocean dive under the close watch of our instructors. It's a game-changer.
- PADI Open Water Certification: Ready to get the license? We can guide you through the whole process and turn you into a confident, certified diver, ready to explore the other 70% of the planet.
- Refresher Course: If it’s been a year or more, a quick skills tune-up is a smart move. We’ll get you back in the water, run through the important stuff, and get your confidence back up before you head out to our premier sites.
A Quick Note on Seasickness
The water off the Kona coast is famously calm, but it never hurts to be prepared. If you're someone who's prone to motion sickness, taking a few simple steps can make all the difference between a good day and a truly epic one.
Don't let a little motion ruin a world-class dive day. Taking preventative measures an hour or two before you board the boat is the best way to ensure you feel great from start to finish.
A couple of tried-and-true options we often recommend:
- Patches & Pills: Products like the Ship-EEZ Seasickness Patch are worn behind the ear for long-lasting relief. Over-the-counter medications like Dramamine or Bonine are also highly effective.
- Wristbands: If you prefer a non-drowsy option, Sea-Band wristbands use acupressure to help keep that queasy feeling at bay.
- Natural Remedies: Many divers swear by ginger chews as a simple and effective way to settle their stomachs.
Your Kona Scuba Diving Questions, Answered
Planning a dive trip to a world-class spot like Kailua-Kona always brings up a few questions. We get it. You want to make sure you've got all the details sorted so you can just relax and enjoy the adventure.
Here, we've gathered the most common queries we hear from divers just like you. Think of this as your personal cheat sheet for planning the perfect underwater experience with total confidence.
What’s The Best Time Of Year For Scuba Diving In Kailua-Kona?
One of the best things about diving in Kona is that it's fantastic all year round. We’re tucked away on the leeward (sheltered) side of the Big Island, which means we’re protected from the big trade winds. Calm, clear water isn't a special treat here; it's just how we live.
Water temps stay wonderfully comfortable, hovering around 75°F (24°C) in the winter and warming up to a balmy 82°F (28°C) by late summer. Visibility is another major plus, often stretching out well past 100 feet. You’ll see everything.
While any day is a great day to be in the water, a couple of seasons have their own special perks:
- Summer (May – October): This is when the ocean gets extra calm and glassy. If you love a smooth boat ride, this is your time.
- Winter (December – March): The diving is still amazing, but you get an unforgettable bonus: listening to the songs of humpback whales echoing through the reef while you dive. It's truly magical.
And don't worry about our most famous residents—the manta rays are here and active year-round, so you won’t miss the main event no matter when you visit.
I'm Not Certified. Can I Still Go Scuba Diving In Kona?
Absolutely! You don't need a certification card to get your first taste of Kona's incredible underwater world. For anyone curious about breathing underwater, we offer a program called Discover Scuba Diving, designed specifically for beginners.
It’s a simple, safe, and super fun introduction. First, a certified PADI Instructor will walk you through the basic safety concepts and skills you need to know. Then, you'll hop in some calm, shallow water to get comfortable with the gear and practice a few easy skills.
Once you’re feeling good, it’s time for the real deal. Your instructor will take you on a guided tour of a beautiful Kona reef. It's an amazing way to see if scuba is for you without committing to a full course. And if you get hooked (fair warning: most people do), we can get you signed up for the full PADI Open Water Diver certification!
What Makes The Kona Manta Ray Night Dive So Special?
There's a reason the Kona Manta Ray Night Dive is consistently voted one of the best dives on the entire planet. It’s more than just a dive; it’s a breathtaking spectacle of nature that happens reliably, night after night.
We head out to a well-known gathering spot and set up a "campfire" of powerful, diver-safe lights on the ocean floor. This light attracts swarms of plankton, which just so happens to be the favorite food of giant manta rays. You are the bait.
You'll settle onto a sandy spot and simply watch as these majestic creatures, some with wingspans over 16 feet, perform a graceful underwater ballet. They glide, swoop, and do barrel rolls just inches over your head to scoop up the plankton.
It’s a surreal, humbling, and utterly unforgettable experience that you'll be talking about for years. Our crew makes sure the entire operation is safe and comfortable, giving everyone a front-row seat to the magic. It's a true bucket-list adventure.
What Should I Bring On A Dive Trip With Kona Honu Divers?
Our goal is to make your day on the water as easy as possible. We’ve got you covered with tanks, weights, and meticulously maintained rental gear if you need it. We also provide reef-safe sunscreen, snacks, and plenty of drinks on board.
All you really need to think about is a small personal bag. Here's a quick checklist:
- Must-Haves: Your certification card and a towel. A change of clothes for after the dives is always a good idea, too.
- Personal Gear: If you have your own mask, computer, or wetsuit that you love, definitely bring it along.
- Hydration: A reusable water bottle is a great way to stay hydrated and help us minimize plastic waste on the island.
- Good Vibes: Most importantly, just come ready to have an amazing time!
One pro tip: if you know you’re prone to seasickness, we highly recommend taking your preferred remedy an hour or two before you get on the boat.
Ready to experience the best Kailua-Kona scuba diving has to offer? From vibrant morning reefs to the unforgettable manta ray night dive, Kona Honu Divers is here to provide a safe, fun, and memorable adventure.
