The Big Island's underwater world is the setting for a dramatic diving experience. With generally warm and calm waters, vibrant coral reefs and rock formations, and plunging underwater drop-offs, the Kona and Kohala coasts offer some premier scuba diving. There are also some good dive locations in East Hawaii, not far from the Hilo area. Divers find much to occupy their time, including marine reserves teeming with tropical reef fish, Hawaiian green sea turtles, an occasional and critically endangered Hawaiian monk seal, and even some playful spinner dolphins. On special night dives to see manta rays, divers descend with bright underwater lights that attract plankton, which in turn attract these otherworldly creatures. The best spots to dive are all on the west coast.
Garden Eel Cove. Only accessible by boat, this is a great place to see manta rays somersaulting overhead as they feast on a plankton supper. It's also home to hundreds of tiny garden eels darting out from their sandy homes. There's a steep drop-off and lots of marine life. Rte. 19, near Kona airport, Kailua-Kona, HI, 96740.
Manta Village. Booking with a night-dive operator is required for the short boat ride to this area, one of Kona's best night-dive spots. If you're a diving or snorkeling fanatic, it's well worth it to experience manta rays drawn by the lights of the hotel. If night swimming isn't your cup of tea, you can catch a glimpse of the majestic creatures from the Sheraton's viewing areas. (You are not allowed to get in the water from the hotel's property.) 78-128 Ehukai St., off Sheraton Kona Resort & Spa at Keauhou Bay, Kailua-Kona, HI, 96740.
Pawai Bay Marine Preserve. Clear waters, abundant reef life, and interesting coral formations make protected Pawai Bay Marine Preserve ideal for diving. Explore sea caves, arches, and lava rock formations and dive into lava tubes. Located ½ mile north of Old Airport is an easy dive spot by boat only. (No shoreline access to protected Pawai Bay is available due to its culturally and environmental significance.) Kuakini Hwy., north of Old Kona Airport Park, Kailua-Kona, HI, 96740.
Puako. Just south of Hapuna Beach State Recreation Area, beautiful Puako offers easy entry to some fine reef diving. Deep chasms, sea caves, and rock arches abound with varied marine life. Puako Rd., off Hwy. 19, Waimea (Hawaii County), HI, 96743.
Hawaii's Manta Rays
Manta rays, one of Hawaii's most fascinating marine-life species, can be seen on some nighttime diving excursions along the Kona and Kohala coasts. They are generally completely harmless to divers, though of course no wild animal is totally predictable. If you don't want to get wet, head to the beach fronting the Mauna Kea Beach Hotel, on the Kohala Coast, or to the Sheraton Kona Resort & Spa at Keauhou Bay, where each evening, visitors gather by the hotel’s lights to watch manta rays feed in the shallows.
The manta ray (Manta birostris), called the devil fish by some, is known as hahalua by Hawaiians.
Its winglike fins, reaching up to 20 feet wide, allow the ray to skim through the water like a bird gliding through air.
The manta ray uses the two large flap-like lobes extending from its eyes to funnel food to its mouth. It eats microscopic plankton, small fish, and tiny crustaceans.
Closely related to the shark, the manta can weigh more than 3,000 pounds.
Its skeleton is made of cartilage, not bone.
A female ray gives birth to one or two young at a time; pups can be 45 inches long and weigh 20 pounds at birth.
Equipment, Lessons, and Tours
There are quite a few good dive shops along the Kona Coast. Most are happy to take on all customers, but a few focus on specific types of trips. Trip prices vary, depending on whether you're already certified and whether you're diving from a boat or from shore. Instruction with PADI, SDI, or TDI certification in three to five days costs $600 to $850. Most instructors rent dive equipment and snorkel gear, as well as underwater cameras. Most organize otherworldly manta ray dives at night and whale-watching cruises in season.
