1. Kealakekua Bay State Historical Park
Kealakekua Bay is more than just a dive site; it's a protected underwater sanctuary and a location of immense historical importance. As a designated Marine Life Conservation District, it offers some of the most vibrant and pristine conditions for big island scuba diving. The bay’s sheltered geography protects it from open ocean swells, resulting in consistently clear water and a thriving, resilient coral ecosystem that attracts divers from around the globe.
The Underwater Environment
Diving in Kealakekua Bay feels like entering a real-life aquarium. The visibility often surpasses 100 feet, revealing a dramatic underwater landscape. The site features a gentle, shallow slope near the shore that gradually drops off to over 100 feet, making it suitable for divers of all experience levels. The reef is a dense tapestry of hard corals, including impressive formations of finger and lobe coral, which provide shelter for a staggering variety of marine life. Divers can expect to be surrounded by massive schools of yellow tang, encounter ornate butterflyfish, and spot Hawaiian green sea turtles (honu) resting on the reef or gracefully swimming by. The bay is also famous for its resident pods of spinner dolphins, which are often seen playing in the distance.
Practical Considerations for Access
The premier diving area within the bay is directly in front of the Captain Cook Monument. A significant practical consideration is that this area is not accessible by road. This limitation is actually a blessing, as it restricts crowds and helps preserve the environment. Divers have three primary methods of access:
- Boat Charter: This is the most popular and practical option for scuba divers. Numerous reputable operators run daily charters, providing easy access and all necessary support. This eliminates the need to haul heavy gear and offers a comfortable and safe way to experience the best of scuba diving Big Island Hawaii.
- Kayak: For the more adventurous, renting a kayak and paddling across the bay is a rewarding experience. Be aware that you must obtain a permit from a state-approved vendor to land your kayak at Kaʻawaloa, the area near the monument.
- Hike: A strenuous 3.8-mile round-trip hike on the Kaʻawaloa Trail leads down to the monument. This route is challenging, with a steep descent and ascent, and is generally not recommended for those carrying heavy scuba equipment.
Tips for a Successful Dive
To make the most of your trip, consider these tips:
- Book an Early Tour: Morning trips often have the calmest waters, the best visibility, and fewer people.
- Protect the Reef: As a protected area, the use of reef-safe sunscreen is crucial to prevent chemical damage to the delicate coral.
- Check Conditions: While generally calm, the bay can be affected by large winter swells. Always check the forecast or with your dive operator before heading out.
- Pack In, Pack Out: There are no facilities (restrooms, water, trash cans) at the monument. You must bring everything you need and take all of your trash with you. You can find more details about enjoying the bay from local experts.
2. Manta Ray Night Dive
Often topping the list of the world's best night dives, the Manta Ray Night Dive is an unforgettable spectacle and a signature experience for big island scuba diving. It’s less of a traditional dive and more of an underwater performance. Divers descend in the dark to a designated sandy area, kneel or lie down, and watch as a powerful light source attracts swarms of plankton, which in turn draws in majestic Pacific manta rays for a feeding frenzy.
The Underwater Environment
The experience is surreal and mesmerizing. Once divers are settled on the ocean floor, typically around 35-40 feet, divemasters place a central light box, creating an "underwater campfire" effect. The light illuminates a column of water, concentrating the plankton. Soon after, giant manta rays, with wingspans reaching over 15 feet, glide in from the darkness. They perform graceful barrel rolls and somersaults, scooping up the plankton just inches above divers' heads in a silent, choreographed ballet. This unique interaction has gained worldwide fame, featured in documentaries like the BBC’s Blue Planet II, and is a site of ongoing research for organizations like the Pacific Manta Research Group.
Practical Considerations for Access
This dive is exclusively accessible via a boat charter, as the primary sites are offshore. The two main locations are "Garden Eel Cove" near the Kona airport and "Manta Village" in Keauhou Bay. The success of this attraction is a testament to the conservation efforts pioneered by local advocates like Keller Laros. It is crucial to book with a Manta Ray Green Listed operator that adheres to strict guidelines to ensure the safety and well-being of the mantas. While this night dive is a focused encounter, the Big Island offers diverse marine experiences. For daytime exploration of vibrant coral gardens and the chance to see spinner dolphins, many visitors explore the waters of Kealakekua Bay. You can learn more about snorkeling captain cook monument to plan a complementary daytime adventure.
Tips for a Successful Dive
To maximize your enjoyment of this incredible dive, keep these points in mind:
- Choose a Responsible Operator: Ensure your chosen company is on the Manta Ray Green List to support sustainable tourism.
- Practice Passive Interaction: This is the golden rule. Never touch, chase, or block the path of a manta ray. Stay on the bottom and let them perform their natural feeding behaviors.
- Manage Buoyancy: Excellent buoyancy control is key to staying put on the sandy bottom without stirring up sediment or floating into the manta's path.
- Consider Motion Sickness: The boat ride and the stationary position on the bottom, where you may feel some surge, can cause seasickness for some. Take medication beforehand if you are susceptible.
- Bring a Light: While operators provide the main lights, carrying your own primary and backup dive light is a standard safety measure for any night dive.
3. Black Water Diving
For the truly adventurous, black water diving offers an experience that is unlike anything else in the world of scuba. This highly specialized type of night dive takes you miles offshore, far from the coastal reefs, to float in the deep, open ocean. Here, you'll witness the largest daily migration of life on the planet as countless deep-sea creatures, often in their larval or juvenile stages, rise from the abyss to the surface waters to feed under the cover of darkness. It is an advanced, surreal, and unforgettable form of big island scuba diving.
The Underwater Environment
The black water environment is best described as "inner space." Divers are suspended in thousands of feet of water, with no visible bottom or surface, tethered to a downline lit by powerful lights. These lights attract an incredible procession of pelagic life that is rarely seen by humans. You won't find coral reefs or large fish here. Instead, the focus is on the bizarre and beautiful macro life: translucent larval fish, vibrant pulsating jellies, tiny cephalopods, and alien-like siphonophores. Many of these creatures are bioluminescent, creating their own light show in the dark. This dive was pioneered for recreational divers in Kona and remains a subject of fascination for marine biologists from institutions like the University of Hawaii.
Practical and Safety Considerations
Due to the extreme nature of the dive, black water diving is only accessible via specialized charters with experienced crews. Safety is paramount and is managed through a robust system. Divers are attached to a weighted downline via a short tether, ensuring they remain connected to the group and the boat at all times. This prevents anyone from drifting away in the open ocean and helps maintain a consistent depth, typically around 40-50 feet. The boat drifts with the current, creating a moving platform for exploration. This is not a dive for beginners; most operators require an Advanced Open Water certification and significant night diving experience.
Tips for a Successful Dive
To properly prepare for this unique adventure, keep the following in mind:
- Master Buoyancy: Perfect buoyancy control is non-negotiable. You will be neutrally buoyant in mid-water for the entire dive with no visual references.
- Book Well in Advance: These trips are offered by only a few operators and have very limited spots. Plan ahead to secure your place.
- Bring the Right Gear: A powerful primary dive light is essential, but an even better tool is a strong focus light for your camera. Underwater photographers will find a macro lens is the best way to capture the tiny, intricate details of the subjects.
- Follow Instructions: Pay close attention to the pre-dive briefing. Your guide's instructions on safety protocols, tether management, and communication are critical. You can discover more about this incredible Kona dive from local operators.
4. Puako Reef and Tide Pools
Located on the sunny Kohala Coast, Puako offers some of the most accessible and rewarding shore diving on the island. This extensive fringing reef system is renowned for its health and biodiversity, making it a must-visit destination for self-sufficient divers looking for a premier big island scuba diving experience without needing a boat. Its numerous entry points and varied underwater topography provide endless opportunities for exploration for divers of all certification levels.
The Underwater Environment
Diving at Puako Reef unveils a vibrant underwater world characterized by intricate lava rock formations, creating a complex habitat of canyons, swim-throughs, and small caverns. The reef starts very shallow near the shore before gradually sloping down to depths of 60 feet or more, with some areas featuring more dramatic drop-offs. The coral cover here is among the most robust on the island, hosting a dense population of reef fish including butterflyfish, parrotfish, and large schools of convict tangs. It is an excellent location to spot Hawaiian green sea turtles (honu) foraging, moray eels peering from crevices, and the occasional whitetip reef shark resting on the sandy bottom. The clear, calm conditions typical of the area provide fantastic visibility for underwater photography.
Practical Considerations for Access
The beauty of Puako lies in its straightforward access. A series of public shore access paths are clearly marked along Puako Beach Drive, allowing divers to choose from several different entry points. Each entry offers a slightly different dive profile, encouraging repeat visits. A significant consideration is the entry itself, which is almost always over uneven lava rock and a shallow reef flat. This requires careful footing and timing with the waves. Unlike managed boat dive sites, Puako is a do-it-yourself location; divers are responsible for their own gear, safety, and dive planning, which is part of the adventure for many experienced in scuba diving Big Island Hawaii.
Tips for a Successful Dive
To ensure a safe and enjoyable dive at Puako, keep these tips in mind:
- Sturdy Footwear is Essential: Wear thick-soled dive booties to protect your feet while walking over the sharp lava rock to your entry and exit points.
- Time Your Dive with High Tide: Entering and exiting over the shallow reef is significantly easier and safer during high tide, providing more clearance over the coral.
- Bring All Your Gear: There are no rental shops or facilities on-site. You must rent tanks and any other necessary equipment from a dive shop in Kona, Waikoloa, or Kawaihae beforehand.
- Respect the Fragile Ecosystem: The tide pools and shallow reef are teeming with life. Practice excellent buoyancy, look but do not touch, and be careful not to damage the delicate coral.
- Check Ocean Conditions: While Puako is often calm, it can be exposed to north and northwest swells, especially in the winter. Always check the surf report before you go. For an in-depth guide to this site, you can learn about the best shore diving spots on the Big Island.

7. Two-Step (Honaunau Bay)
Two-Step, officially named Honaunau Bay, is one of the most celebrated and easily accessible shore diving sites on the entire island. Located directly adjacent to the sacred Puʻuhonua o Hōnaunau National Historical Park, the site blends incredible marine biodiversity with deep cultural history. It gets its famous nickname from the convenient, two-tiered lava rock formation that creates a natural staircase into the ocean, making it a prime location for big island scuba diving.
The Underwater Environment
The bay is a protected, calm body of water that offers fantastic conditions for divers of all skill levels. Visibility is consistently excellent, often reaching 80-100 feet. The entry area opens into a shallow, sandy-bottomed plateau at about 10-20 feet, which is covered in intricate coral heads and bustling with reef fish. This makes it an ideal spot for checkout dives, skills practice, or simply enjoying a long, relaxed dive profile.
Venturing further out, the seafloor gradually slopes down to over 100 feet, revealing extensive coral gardens and more complex underwater topography. Divers are almost guaranteed to encounter Hawaiian green sea turtles (honu) resting or feeding on algae. The reef is home to moray eels, octopuses, and a vibrant array of fish, including butterflyfish, parrotfish, and wrasses. It's also common for pods of spinner dolphins to visit the bay for rest and play, offering a magical surface interval or a distant underwater sighting.
Practical Considerations for Access
Two-Step's primary appeal is its straightforward shore access, which sets it apart from many other premier sites that require a boat. Divers can park (for a small fee in the adjacent private lot) and walk just a few feet to the entry point. The lava "steps" provide a stable platform for gearing up and making a simple giant stride entry into the water. This accessibility makes it a favorite for those who prefer to scuba diving Big Island Hawaii on their own schedule. However, its popularity means it can get very crowded, particularly mid-day.
Tips for a Successful Dive
To maximize your experience at this popular spot, keep these tips in mind:
- Time Your Visit: Arrive early in the morning (before 9 AM) or later in the afternoon (after 3 PM) to avoid the peak crowds from snorkel tours and other visitors.
- Be Aware of Currents: While the inner bay is typically very calm, currents can become stronger as you move towards the northern and southern points or further out from shore.
- Gear Up for the Entry: Sturdy dive booties are essential for walking on the sharp, uneven lava rock. Be cautious and take your time when entering and exiting the water.
- Make it a Day Trip: Plan to visit the Puʻuhonua o Hōnaunau National Historical Park next door. Learning about the "Place of Refuge" provides a profound context for the natural beauty you are about to experience.
- Pack Accordingly: Facilities are limited to portable toilets. Bring your own water, food, and reef-safe sunscreen, and be prepared to pack out everything you bring in.

Final Thoughts
Embarking on a journey into the waters of Hawaii's largest island is to prepare for an underwater experience unlike any other. As we've explored, big island scuba diving is not a singular activity but a rich tapestry of diverse adventures, each woven from volcanic fire and oceanic life. From the hallowed, history-rich waters of Kealakekua Bay to the surreal, alien-like world of a Black Water Dive, the options are as varied as the island's own microclimates. The key takeaway from this guide is not simply that the diving is good; it's that the quality of your experience is directly proportional to the quality of your planning and your choice of guide. Understanding the nuances between a shore dive at Two-Step and a charter-led Manta Ray Night Dive is the first step toward crafting an unforgettable itinerary.
The most critical decision you will make, beyond which reef to explore, is which operator will guide you. The Kona diving companies we’ve detailed each offer a different flavor of aloha and expertise. Your choice should be a deliberate one, based on your certification level, your specific interests, and the kind of atmosphere you seek. For advanced divers seeking a challenge or underwater photographers who need a steady platform, the choice of operator is paramount. This is where a company’s philosophy truly matters. A key insight for serious divers is to consider operators who dedicate their charters exclusively to scuba. For example, Kona Honu Divers stands out by maintaining a "divers-only" policy on their boats. This isn't an arbitrary rule; it's a commitment to a streamlined, efficient, and focused dive experience, eliminating the logistical dance of accommodating both snorkelers and divers on the same trip. This approach ensures that every aspect of the charter, from briefing to boat positioning, is optimized for the best possible scuba diving Big Island adventure.
Actionable Next Steps for Your Dive Plan
With the vast potential of diving Hawaii Big Island, moving from inspiration to implementation is key. Here’s how to channel your excitement into a concrete plan:
- Honest Skill Assessment: Before you book anything, honestly evaluate your and your group's comfort and certification levels. Are you looking for a relaxed "discover scuba" experience, or are you an advanced diver ready for the deep, dark thrill of a Black Water dive? This will immediately narrow your focus.
- Prioritize Your "Must-Dive" List: Is the Manta Ray Night Dive your non-negotiable bucket list item? Or are you more drawn to exploring the intricate lava tube formations and pristine coral gardens during the day? Decide on your top one or two priorities to build your trip around.
- Align with the Right Operator: Use the insights from this guide to match your priorities with a company’s specialty. If you’re a mixed group of divers and non-divers, a fantastic option like Kona Snorkel Trips, paired with a dedicated dive boat for the certified divers, ensures everyone has a world-class day on the water. If your entire group is certified and focused, a dedicated operator is your best bet.
- Book Well in Advance: The secret is out about Kona diving. The best charters, especially the unique ones, fill up weeks, if not months, ahead of time. Procrastination can lead to disappointment. Secure your spot, especially during peak travel seasons, to ensure you dive with your first-choice company.
Mastering this thoughtful approach transforms your trip from a simple vacation to a true underwater expedition. The scuba Big Island experience is a profound connection to a powerful, living ecosystem. It’s about feeling the deep hum of the ocean, witnessing the silent ballet of manta rays, and exploring a dramatic sub-aquatic landscape that is still being shaped by volcanic forces. Your adventure awaits in the deep blue off the Kona coast.
When you're ready to book an excursion with a team renowned for its professionalism, safety, and award-winning focus on the diver's experience, explore the charters offered by Kona Honu Divers. As the highest-rated and most-reviewed operator in Kona, their commitment to creating the ultimate big island scuba diving adventure is unmatched.

Frequently Asked Questions
Is there good diving on the Big Island?
Yes, the Big Island offers arguably the best and most diverse scuba diving in the entire Hawaiian archipelago. Its unique volcanic underwater topography creates stunning lava tubes, arches, and caverns. The leeward Kona coast provides clear, calm, and warm waters year-round, and the island is home to world-famous, unique dives like the Manta Ray Night Dive and Black Water Dives that you cannot reliably experience anywhere else.
What are the best months to scuba dive in Hawaii?
While you can scuba dive in Hawaii year-round, the best conditions are typically found from April to October. During these months, the ocean is generally calmer, the water is warmer (averaging 77-80°F or 25-27°C), and visibility is excellent. The winter months (November to March) can bring larger ocean swells, particularly on north and east-facing shores, but the protected Kona coast often remains calm and very diveable.
Is Kona good for scuba diving?
Kona is the undisputed hub of scuba diving Big Island Hawaii. Its western-facing coastline is sheltered from the prevailing trade winds by massive volcanoes, creating consistently calm and clear conditions perfect for diving. This has allowed a thriving ecosystem of coral reefs and a high concentration of world-class dive operators and accessible dive sites, making it the premier destination for divers visiting the island.
Is it better to snorkel or scuba dive in Hawaii?
This depends entirely on your goals and comfort level. Snorkeling is highly accessible, requires minimal equipment, and is fantastic for viewing the vibrant shallow reefs found in protected bays like Kealakekua Bay. However, scuba diving offers a completely different, far more immersive experience. It allows you to explore deeper reefs, interact with marine life in its natural habitat for extended periods, and access unique environments like lava tubes and the deep-water columns for Black Water and Manta Ray Dives.
Which Hawaiian island is best for scuba diving?
While Maui, Oahu, and Kauai all offer excellent diving opportunities, the Big Island is consistently ranked as the best for scuba diving. Its superiority comes from the sheer diversity and uniqueness of its dive sites. The combination of pristine coral reefs, dramatic volcanic underwater landscapes, and iconic, world-renowned dives like the Manta Ray Night Dive gives it a distinct edge over the other islands.
When to dive Kona?
You can enjoy phenomenal diving in Kona at any time of the year. The Kona coast is on the leeward side of the island, meaning it is protected from the winds and weather that affect other parts of the island. For the absolute calmest sea conditions, plan your trip during the summer months (June-September). However, winter diving is also excellent and offers the added bonus of potentially hearing humpback whales singing underwater during their migration season (December-March).
