The abundance of healthy coral formations provides a vibrant backdrop for an array of marine life, including manta rays, graceful sea turtles, and schools of colorful reef fish. Whether you prefer exploring from the shore or embarking on a boat dive, the Kona Coast offers a plethora of options. Water temperatures remain consistently pleasant, ranging from 75-85°F year-round, making it an ideal destination for big island diving regardless of the season. This area truly deserves its top spot on any big island diving list due to the sheer variety and accessibility it offers all levels of diving experience.

2. Manta Ray Night Dive

The Manta Ray Night Dive is arguably the most sought-after big island diving experience. This mesmerizing underwater ballet takes place off the Kona coast, where giant manta rays gather to feed on plankton attracted by powerful dive lights. This unique spectacle has become synonymous with Big Island diving, attracting enthusiasts from across the globe.

How it works: Dive operators position underwater lights on the ocean floor at specific sites known as Manta Village (Keauhou Bay) and Manta Heaven (Garden Eel Cove). Divers and snorkelers gather in a circle, pointing their dive lights upwards, creating a glowing beacon that attracts plankton. The manta rays, with wingspans sometimes exceeding 16 feet, then glide gracefully through the illuminated water, performing acrobatic maneuvers as they feast on the microscopic organisms. The dive depth is typically 30-40 feet, making it accessible to divers of various certification levels. For those who aren't certified divers but still want a close encounter, consider a manta ray night snorkel in Hawaii.

3. Black Water Night Diving

For a truly unique and otherworldly big island diving experience, consider black water night diving. This advanced, specialized dive takes you several miles offshore, suspending you in the deep ocean, typically in 3,000-6,000 feet of water, under the cover of darkness. The goal is to witness the mesmerizing diurnal vertical migration, where a plethora of pelagic and planktonic creatures ascend from the depths to the surface under the cloak of night. It's a chance to glimpse rarely seen deep-sea organisms and the juvenile stages of ocean species, many of which are bioluminescent, creating a breathtaking spectacle.

Black water dives are conducted 3-5 miles offshore, where the water reaches profound depths. Divers are tethered to a downline equipped with lights, providing a point of reference and ensuring safety in the vast open ocean. Because of the challenging environment and unique procedures, this type of big island diving is generally reserved for advanced divers comfortable with night diving and open water conditions. Floating in mid-water, with no bottom reference below, provides a unique sensory experience unlike any other dive.

Kona coast black water dives, in particular, have yielded incredible sightings, documenting larval fish, juvenile squids, and a host of pelagic invertebrates seldom seen by humans. Underwater photographers have captured stunning images of transparent larvae and otherworldly bioluminescent organisms.

4. Lava Tubes and Underwater Caves

Big Island diving is renowned for its unique volcanic topography, and exploring the underwater lava tubes and caves is an experience unlike any other. These fascinating geological formations were created by ancient lava flows, resulting in a network of underwater tunnels and swim-throughs. They offer a glimpse into Hawaii's fiery past and provide a haven for unique marine life, making them a must-do for adventurous divers.

These underwater tunnels range from large, cathedral-like caverns to narrow passages, creating a diverse and exciting underwater landscape. Dive depths vary from 20 to 80 feet depending on the specific site. As sunlight filters through cracks and openings in the lava rock, dramatic light beams illuminate the caves, creating spectacular photographic opportunities. These unique environments are also home to specialized cave-dwelling species, adding another layer of intrigue to the dive.

Why Explore Lava Tubes on the Big Island?

Lava tube diving deserves a spot on any Big Island diving itinerary because it offers a truly unique experience. This type of geological diving is not readily available in many other parts of the world. The caves provide protection from currents and surge, offering a calmer diving environment, particularly beneficial during rougher surface conditions. The play of light and shadow within the caves creates an otherworldly ambiance, perfect for capturing stunning underwater photos. Moreover, the enclosed environment can offer a cooler diving experience, a welcome respite during the hot summer months.

5. South Point (Ka Lae) Diving: An Untamed Big Island Diving Experience

South Point (Ka Lae), the southernmost point of the Big Island and the United States, offers a distinctly different big island diving experience compared to the more frequented Kona coast. This area beckons adventurous divers seeking pristine, less-visited waters teeming with unique marine life. Here, dramatic underwater topography, sheer drop-offs, and the confluence of ocean currents create a nutrient-rich environment attracting larger pelagic species and offering a thrilling sense of exploration.

6. Kohala Coast (North Kona) Diving

For a truly distinct big island diving adventure, venture north along the coast to the Kohala region. While Kona further south boasts renowned dive sites, the Kohala Coast offers a different flavor of underwater exploration, characterized by diverse topography, thriving coral gardens, and unique marine life. This area caters to a variety of experience levels, from beginner divers exploring shallow reefs to advanced divers plunging into dramatic drop-offs.

7. Hilo Side (East) Diving: An Untamed Big Island Diving Experience

While the Kona side of the Big Island often steals the spotlight for diving, adventurous souls seeking a different kind of underwater magic should look east. Hilo side (East) diving offers a unique perspective on Big Island diving, characterized by dramatic volcanic landscapes, fascinating brackish water ecosystems, and a distinct array of marine life. This rainier side of the island presents a more challenging, yet profoundly rewarding, diving experience.

The magic of Hilo side diving lies in the confluence of freshwater springs and ocean water. This creates unique brackish water environments and haloclines – visible layers of differing water salinity – that offer stunning photographic opportunities. Divers can explore dramatic black sand slopes, lava tubes, and rock formations, all teeming with marine life specifically adapted to these conditions. You'll encounter species here that you won't find on the west side, making it a must-do for experienced divers and underwater photographers.

Before you grab your fins, it’s crucial to understand that Hilo side diving requires more planning and flexibility due to the frequently changing weather conditions. Visibility can be affected by rainfall, and currents and surge can be stronger than on the Kona side. The dive infrastructure is also more limited, with fewer operators and shore entry points. However, these challenges are often outweighed by the rewards: far fewer divers, an unexplored feel to many sites, specialized marine life, and lower diving costs compared to Kona.

Examples of dive sites include Leleiwi Beach Park, known for its freshwater springs creating mesmerizing haloclines; Richardson's Ocean Park, offering unique lava tubes and black sand dives; and pre-2018 eruption, the Kapoho Tide Pools were renowned for their warm, thermal features.

• Check conditions carefully before each dive, as they can change rapidly.
• Plan your dives during the drier months (typically summer and early fall) for the best visibility.
• Bring macro photography equipment to capture the unique critters found on this coast.

Hilo side diving earns its place on this list by offering a completely different perspective on Big Island diving. It caters to the adventurous spirit, rewarding those who embrace the challenge with unforgettable encounters with unique ecosystems and marine life. While it's not for the faint of heart, experienced divers, underwater photographers, and marine life enthusiasts will find it an incredibly rewarding addition to their big island diving adventure.
