Dive into the Depths of Big Island Diving
Discover seven exceptional Big Island diving experiences, perfect for every skill level. This list highlights top dive sites, from the famed Manta Ray Night Dive to exploring lava tubes at Place of Refuge. Learn why these locations are a must for any diver visiting Hawaii and start planning your underwater adventure.
1. Kona Coast Manta Ray Night Dive
The Kona Coast Manta Ray Night Dive is a truly exceptional experience, ranking high on the list of must-do big island diving adventures. This world-renowned dive offers a unique opportunity to witness the graceful ballet of manta rays feeding in their natural habitat. Divers kneel or lie on the ocean floor with dive lights pointed upwards, attracting plankton. These microscopic organisms, in turn, draw in the majestic manta rays, creating an unforgettable spectacle just inches above divers' heads. These gentle giants, some with wingspans reaching up to 16 feet, glide effortlessly through the water, filtering the plankton with their massive cephalic fins.
This dive's accessibility contributes significantly to its popularity. Relatively shallow depths of 30-40 feet make it suitable for divers of all certification levels, from novice open water divers to seasoned professionals. The dive is conducted at night, adding an extra layer of mystique and excitement, with underwater lights enhancing the visibility of these magnificent creatures. Conveniently located near Kona Airport and dive sites like Garden Eel Cove, it’s easy to incorporate into any big island diving itinerary.
Several factors contribute to the Kona Coast Manta Ray Night Dive's prominent place among big island diving experiences. Consistent manta ray sightings year-round offer a high success rate of encounters, making it a truly once-in-a-lifetime experience. It's also an excellent opportunity for underwater photography, capturing stunning images of these graceful creatures. Many operators are conservation-focused and educate divers about manta ray protection and responsible wildlife interaction. For non-divers, there's a fantastic alternative. If you're not SCUBA certified, you might want to experience the magic from the surface. For a truly unique experience, consider a manta ray night snorkeling adventure, as described in "Manta Ray Night Snorkel in Hawaii: An Unforgettable Experience" by Kona Snorkel Trips.
While the Kona Coast Manta Ray Night Dive is an incredible experience, it's important to be aware of potential drawbacks. It can get crowded, especially during peak tourist seasons, impacting the intimacy of the experience. Night diving might be intimidating for inexperienced divers, and occasional weather-related cancellations can occur. Some operators might rush the experience to accommodate multiple groups, potentially shortening bottom time.
Garden Eel Cove (often referred to as Manta Heaven) hosts the most popular manta ray night dive, while Manta Village at Keauhou Bay offers a slightly less crowded alternative for big island diving enthusiasts. To enhance your experience, consider booking with operators who follow responsible wildlife interaction guidelines, crucial for the well-being of these gentle giants. Bringing a backup underwater light is advisable, and wearing extra thermal protection is recommended as you'll remain relatively stationary in the water. Booking a combo sunset/manta dive can maximize your experience, providing an unforgettable transition from day to night. Remember to avoid using flash photography, as it can disorient the mantas. Pioneering dive operators like Jack's Diving Locker, along with the Manta Pacific Research Foundation and numerous National Geographic and BBC documentaries, have all contributed to popularizing this exceptional big island diving experience.
2. Two Step (Honaunau Bay)
Two Step, nestled within the tranquil Honaunau Bay adjacent to Pu'uhonua O Honaunau National Historical Park (Place of Refuge), is a jewel in the crown of Big Island diving and snorkeling sites. Its name derives from the naturally formed two-step lava rock formation that simplifies entry and exit from the water. This protected bay provides an exceptional experience for all levels, from beginners taking their first breaths underwater to seasoned divers exploring the deeper reaches. The appeal lies in the combination of easy accessibility, vibrant marine life, and the historical significance of the location. This sheltered bay offers typically calm waters, crystal-clear visibility often exceeding 100 feet, and a diverse coral reef ecosystem that gently slopes from the shoreline into deeper waters, making it perfect for big island diving.

Beginners can explore the shallow reefs teeming with colorful reef fish, while more experienced divers can venture into lava tubes, swim-throughs, and deeper sections. The 'Amphitheater,' a popular section of the reef, is known for its large schools of yellow tangs and butterflyfish. Another highlight is the 'Turtle Cleaning Station,' where green sea turtles regularly congregate. Early morning dives often reward divers with encounters with spinner dolphins.
Two Step’s shore entry, using the natural lava rock 'steps,' makes it a fantastic option for budget-conscious big island diving enthusiasts, as no boat is required. This convenient access also makes it suitable for families and groups with varying levels of experience, where some might prefer snorkeling while others dive.
