Bubbling volcanoes, black sand beaches, entrancing hula dancers, and magnificent waves: Sound familiar? Indeed, Hawaii is as famous as it is beautiful, with its spectacular scenery and laid back lifestyle.

These are the islands where leafy green cliffs cascade down into frothing white water, and comfortable breezes blow across the breathtaking beaches. Scuba diving in Hawaii is as popular here as surfing, and there are more than enough dive sites to sink your teeth into. If you want to live your best life and #LiveUnfiltered then Hawaii is the place to do it!


Hawaii

Hawaii is a place unlike any in the world. As a piece of the United States, it adds an extra element of intrigue, a blending of cultures and mindsets. Hawaii became a state in 1959, and is the 50th – the most recent addition. Found far out in Oceania, scuba diving in Hawaii is unlike any other state, with tropical and warm throughout the year.

With around 750 miles (1,210 kilometers) of coastline, Hawaii is a huge tourist destination, bringing travelers from around the world. But beaches aren’t all that this archipelago has to offer. Some of the most fantastic volcanoes in the world can be found here, pumping out lava at tremendous rates. Some flows make their way to the sea, sputtering and hissing as they melt into the waves.

This unreal amount of volcanic activity is what formed these islands to begin with, from the soaring cliffs to the fertile jungled hills. This abundant landscape offers you new sights and sounds, tastes and sensations, both above the water and below. Let’s take a look at the dives you can expect in each island of this beautiful state.


Scuba Diving in Hawaii by Island

Kaua’i

Kaua’i is the oldest of the Hawaiian Islands, geologically speaking. It is known as the “Garden Isle,” because it is carpeted with lush greenery. The fertile landscape is home to an abundance of farmland and animal life, including plenty of wild chickens, which can be seen and heard all over the island.

If you crave some sea turtle sightings, Kaua’i is your place. Some of the best dives on the island can be found off its southern shore. Swim in a collapsed lava tube with hundreds of green sea turtles in Sheraton Caverns, or find even more of your flippered friends at Turtle Bluffs. The Bluffs are a cleaning station for turtles, and you can even spot some fairly large reef sharks in the shallows. There are even more turtles at Tunnels Beach, where they glide between mysterious lava formations.

On the western side of the island, the little known Mana Crack is a lovely spot to add to your logbook. You can soar down to depths near 95 feet (29 meters). Another deep dive is Ahukini Landing, on the eastern side of the island.

For shore diving, don’t miss out on Koloa Landing, where the fantastically colored Dragon Moray eel can be found. This eel comes in a variety of hues, bright and white spotted, and its two unique horns are what gives it its name.

You can fly onto the island into the Lihue Airport and then get around the island by a series of interconnecting highways. Be sure to take the Holo Holo Koloa Scenic Byway, which will take you through some of the most remarkable features on Kaua’i.

Moloka’i

Known as the “Friendly Island,” Moloka’i is found in the middle of the Hawaiian archipelago. From here you can get lovely views of many of the other islands, and you can even see the twinkling lights of Honolulu on still, clear nights. The island itself is made up of two massive volcanoes, and the highest sea cliffs in the world can be found on these shores.

What’s more, the longest fringing reef in the United States, and at nearly 25 miles (40 kilometers) long, you’ll want to explore every bit of it. Because it is relatively difficult to get to the island, you may find that you have the reef almost entirely to yourself. There is rare, endangered sea life in these waters, and photographic opportunities abound.

One of the most popular sites on Moloka’i is Fish Bowl, where you might even run across an occasional Hawaiian Monk Seal, a rare treat. In deeper water, hammerhead sharks are not uncommon, sometimes making their way in huge schools.

You can only get to Moloka’i through domestic flights from Maui or Honolulu. You can also get from Maui to Moloka’i via ferry; a lovely ride. Once on the island, there is only one main highway, meandering along the length, from tip to tip. The mile markers on the road are used as reference points, so be sure to take note when you pass one of the helpful green signs.

Lana’i

Small Lana’i is off the beaten path, and is a quiet, off the grid destination. Long ago, native Hawaiians regarded Lana’i with deep reverence, believing it to be a place inhabited by dark spirits. Only more recently have people been frequenting the island on vacations, and there are several hotels and golf courses.

Cavern divers, start your engines! Lana’i offers exceptionally clear water and an abundance of caves. Two of the best caverns to check out are Cathedrals I and II, both of which are splendid and deserve a dive or two. If you come during the winter, you will probably see humpback whales, and may even get a chance to dive with these ethereal animals.

There is more than just caves on Lana’i, however. Shore dive in Manele Bay, where plenty of rays and reef fish coalesce. Fish Rock is another great shore dive, but you can also take a boat there if you just can’t kick anymore.

You cannot fly to straight to Lana’i, but must take a flight from either Honolulu or Maui. If you prefer, you can take an hour long ferry ride, leaving from Maui. Once on the island, you can either take the transit offered by the hotels, or rent a four wheel drive vehicle and take to the roads yourself, exploring the unique nature on your own terms and at your own pace.

Hawai’i

The island for which the great state is named, Hawai’i is the largest of the Hawaiian Isles. Known colloquially as the “Big Island,” Hawai’i is made up of five volcanoes: Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea. Both Mauna Loa and Kilauea are found within the astounding Hawai’i Volcanoes National Park. The mighty Kilauea has been constantly erupting for more than 20 years.

There are dozens upon dozens of dive sites scattered around the perimeter of Hawai’i. Explore bizarre underwater lava formations, or watch curious turtles munching on sea grasses. The most famous dive on the island is the unforgettable Kona manta ray dive. Kneeling on the sandy sea floor, hundreds of tremendous rays skate above your head. This dive is not to be missed.

If you want to shore dive, don’t miss out on Kamakahonu Beach, and the excellent Honokohau Harbor. Night diving is a heart-pounding experience, no matter where you find yourself. Often, large creatures make their way upward from the black depths, surprising you during their swift ascent.

Highways crisscross the expanse of the island, interconnecting the main towns of Hilo and Kailua-Kona. You can fly into either one of these towns. There are rental cars and taxis to take you where you need to go, as well as a notoriously slow bus route that makes its way around the perimeter of the island.

O’ahu

Oahu is the most populous (and popular) of the Hawaiian Islands. The capital city of Honolulu can be found here, a booming metropolis, so starkly contrasting to the uninhabited jungles of other islands. You can expect plenty of both rain and sun during your stay, with plenty of rainbows to boot. The beaches here are some of the most famous in the world, with Waikiki Beach taking the cake, an undeniably gorgeous stretch of sand and sea.

Head to O’ahu for stellar wreck dives. The San Pedro and YO-257 can both be experienced on the same dive. To add to the excitement, a passenger submarine often comes to check out the wrecks, and you can make some silly faces back and forth with the people riding within.

Shore diving is the name of the game on O’ahu, where you can experience wrecks, caverns, and fantastic reefs. During the summer, the waves subside, and the North Shore becomes available. Don’t miss out on Shark’s Cove, an aptly named dive where you can run into an array of impressive species, including the massive tiger shark.

To add to the diversity of dives, see the fantastic walls like Waimea and Wailalua. Both require a boat to access, but on Hawaii there are plenty of vessels to choose from.

Check out some of the lovely islands that dot the shoreline, from Waikiki to tiny Manana Rabbit Island. You can find a wide diversity of creatures and formations beneath the water at these excellent sites.


As far as attractions on land go, the beautiful Valley of the Temples Memorial Park is not to be missed, found on the eastern side of the island. The memorial of Pearl Harbor is also found on Oahu, and you can tour the USS Arizona Memorial during your stay.

You will probably fly into Honolulu, where the large international airport is located. Honolulu is a gateway to the other islands and you can catch flights to all of the smaller islands from this hub. The southern shore of the island is highly populated, but the northern shore is much less so.


Maui

Maui

Marvelous Maui is a favorite with visitors, with its diverse landscape and stunning beaches. The island was formed by two volcanoes, whose virulent lava flows connected to form an isthmus. Kahului is the largest city on the island and is found at the juncture of the two volcanoes.

The icon of Maui is Haleakala. The massive, inactive Haleakala volcano is 5 miles (8 kilometers) from the summit to the seafloor, stretching 10,000 feet (3,000 meters) above sea level. Clouds shroud the mountain for most of the year, dumping down an incredible amount of rain. At the highest elevation, temperatures below freezing are not uncommon, and this alpine environment provides a shocking contrast to the hot, humid jungle below.

Dragon Reef is an exceptional dive on the southwestern shore of the island. You can reach the reef by boat, and depths range from 25-70 feet (7-21 meters). One of the most popular dives is Black Rock, where eagle rays and turtles idle. There are also several wrecks worth your time, especially the Carthaginian.

Offshore is horseshoe shaped Molokini, an extinct volcano with unreal sites. Diving the Molokini crater is an unexpected and lovely experience, where some of the most pristine, clear waters in Hawaii can be explored. Plenty of sharks flock here, and there are several places where you can swim with a variety of species, even hammerheads. Plus, the drift diving here is some of the best in the world, especially along the back side of the crater.

Be sure to see the humpback whales during their annual migration. They can be seen through the end of April, but are most common in the winter, where they breed and give birth to their young in the warm waters.

Maui is most easily visited via airline, either from an international destination or from another of the islands. Once on the island, rent a car or take a taxi to get around the island. If renting a car, a four wheel drive vehicle is highly recommended, especially if you are heading out on far flung treks. Maui is a great starting off point and the Maui ferry can take you to plenty of the other less visited islands in the archipelago.
