The following summary box highlights the key features that make Kona Honu Divers a standout choice.

These core principles translate to a high-quality, personalized, and professionally managed experience for every diver. Kona Honu Divers offers a wide array of scuba diving tours on the Big Island designed for every skill level.

The Manta Ray Night Dive is arguably Kona's most iconic underwater attraction, a world-renowned spectacle that defines the ultimate Kona diving adventure. Divers descend after sunset to a designated sandy area, often referred to as the "campfire," where powerful lights are placed on the ocean floor. These lights attract immense clouds of plankton, the primary food source for manta rays. Within minutes, majestic Pacific Manta Rays, with wingspans up to 16 feet, glide in from the darkness to gracefully feed on the plankton, performing an acrobatic ballet just inches above the divers' heads.

This experience, popularized by pioneers and showcased in major documentaries, offers an unparalleled, non-invasive encounter with these gentle giants. Premier sites like Manta Village and Manta Heaven provide consistent sightings, creating one of the most memorable and sought-after night dives on the planet. To ensure a safe and respectful interaction, it's vital to stay on the seafloor, practice good buoyancy, and avoid direct contact with the mantas. For those prone to seasickness, taking preventative measures is also highly recommended. The experience is truly a must-do for any certified diver visiting the Big Island.

Booking a dedicated manta ray dive tour is the best way to witness this incredible natural phenomenon. An experienced guide will handle the logistics, provide a thorough safety briefing, and ensure the dive is conducted with the utmost respect for the marine environment.

For a truly unique geological adventure, experienced divers can book a special day trip from Kona to explore the legendary dive sites off the coast of Lanai. The Cathedrals, both I and II, are awe-inspiring underwater lava tubes that form massive caverns. Sunlight filters through openings in the ceiling, creating dramatic shafts of light reminiscent of stained-glass windows in a cathedral. These sites offer an unparalleled opportunity for cavern diving, with vast chambers and intricate swim-throughs.

Exploring these formations requires confidence and excellent buoyancy control to navigate the overhead environments safely without disturbing the delicate ecosystem. Cathedral I is known for its expansive main chamber and a "black coral" altar, while Cathedral II offers a more complex network of smaller passages. These advanced dives are a must-do for photographers and thrill-seekers looking for a different kind of Hawaiian diving experience beyond the typical reef tour. Due to the travel time and skill required, these charters are specialized trips and an excellent choice for those seeking a full day of premier advanced diving adventure.

As one of Kona's most established dive operations, Jack's Diving Locker is a foundational part of the local scuba community.

The summary box below highlights the key features that make Jack's Diving Locker a well-regarded choice.

These attributes ensure a dependable and educational experience for divers of all skill levels.

As a protected marine sanctuary, Kealakekua Bay offers some of the most pristine conditions for Kona diving and snorkeling. This historic bay, where Captain Cook first landed, is celebrated for its exceptional water clarity, vibrant coral gardens, and teeming marine life. Its status as a Marine Life Conservation District (MLCD) means its delicate ecosystem is exceptionally well-preserved, creating a thriving underwater environment that feels like swimming in an aquarium.

The area near the Captain Cook Monument is a prime spot for both diving and snorkeling, with steep drop-offs and healthy reefs attracting large schools of fish, eels, and occasional turtles. Due to its protected nature, access is limited, which helps maintain its untouched beauty. The bay's calm, clear waters are ideal for all skill levels, from beginners making their first dive to experienced divers seeking unparalleled photography opportunities.

To get the most out of a visit, plan to enter the water early in the morning when conditions are calmest. It's crucial to adhere to all regulations, including no-fishing rules, and to use only reef-safe sunscreen to protect the fragile coral. While spinner dolphins frequent the bay, remember that federal law requires maintaining a 50-yard distance to avoid disturbing them.

For experienced divers seeking a true adventure, South Point (Ka Lae) offers some of the most challenging and rewarding kona diving available. As the southernmost tip of the United States, this remote area is exposed to powerful ocean currents that attract large pelagic species. The underwater landscape is a dramatic tapestry of volcanic formations, deep walls, and offshore seamounts, promising a dive that is as thrilling as it is beautiful.

This area is strictly for advanced divers due to its unpredictable conditions and depth. Successful dives here, such as drift dives along Ka Lae Point or explorations of offshore pinnacles, often yield encounters with sharks, jacks, and other open-ocean visitors. Proper planning, including diving only in optimal weather and with an experienced local guide, is non-negotiable. An Advanced Open Water certification is the bare minimum, and divers must be proficient in managing strong currents and deep dive profiles. While not accessible by boat charter, you can find more about the island's many shore diving options, including some in this region, by reading this guide to the best shore diving sites in Kona, Hawaii.

The following summary highlights key considerations for diving at South Point.

These principles ensure that a dive at South Point is undertaken with the necessary caution and respect for its powerful environment.
