Molokini Backwall1

Molokini Backwall

5.0(13 reviews)Molokini, Maui, Hawaii

An advanced dive, the Molokini Backwall is a world class wall and drift dive for certified divers only. The Wall is approximately 300ft in depth, however, divers will level off at 80 ft or less. You may see white tip, black tip, and gray reef sharks, manta rays, dolphins and schooling fish. If you travel in the winter months (Oct-Mar) you will most likely run across humpback whales. This can be a drift dives at times, but the current was almost undetectable when I went.

Lanai Cathedrals2

Lanai Cathedrals

5.0(5 reviews)Lanai, Hawaii

Off the island of Lanai is a remarkable dive spot known as Lanai Cathedrals. Inside pockmarked lava tubes, beams of light stream in with an ethereal glow creating an underwater cathedral. This beautiful dive is one you won't soon forget. After you take in the gorgeous views, exiting the cathedral can be quite a rush. There is a fun spot where there is a lava shoot where the surge can shoot you out as you exit the cathedral called 'shot gun'. Reef sharks, turtles, and many species found only in Hawai'i live around Cathedrals I and II (First Cathedral and Second Cathedral). With a max depth of 19 metres/65 feet and reliable visibility, Lanai's Cathedrals are accessible for divers of all experience levels. The most common way to dive Lanai Cathedrals is by booking a boat trip from Maui.

Ahihi Cove3

Ahihi Cove

4.7(15 reviews)Maui, Hawaiian Islands

This is a must-do site! This picturesque area is perfect for beginners and advanced divers alike. The entry is easy, and the fish are friendly (they know they're protected here)! There are no facilities here, and the parking is limited-- but don't let that deter you! At the South End of Highway 31, bear right onto Wailea Iki. Continue to the T, turn left on Wailea Alanui, which becomes Makena Alanui. After 5.0 miles, you'll see the cove.

Five Caves4

Five Caves

4.7(22 reviews)Maui, Hawaiian Islands

Five Caves is know by several names including Five Graves and Nahuna Point. This is a must-do dive for Maui, as the entry is easy and formations and sea creatures are impressive. If it is your first time to the area, a guide is recommended to ensure you find the caves on your first dive. The nearest facilities are at Makena Landing, just a short drive up the road. Vast reef with plenty to see. There are five caves found throughout the site. Aquatic life includes: pacific snake eel, schools of needlefish, and the infamous green sea turtles. This site is located right next to an old cemetery, thus the correct name "Five Graves". I think dive boat operators want to call it 5 caves so you don't realize it is such a great shore dive! There is no beach and no facilities. You need to climb down a little wall into the water, but it is well worth it. Five Caves is also known as Five Graves. At the South End of Highway 31, bear right onto Wailea Iki. Continue to the T, turn left on Wailea Alanui. After 2.2 miles, turn right onto Makena Road. In a couple of hundred yards, you'll see the parking area.

Lana'i Lookout (Scenic Lookout)5

Lana'i Lookout (Scenic Lookout)

4.7(17 reviews)Oahu, Hawaiian Islands

Lana'i Lookout is not for the faint of heart. It is for 'extreme divers' only. Fortunately, not too many novices find their way to this extremely challenging spot. You will make your entry by giant stride to the left of the lookout, and exit to a small rocky patch to the right. Again, an experienced guide is a must! Ask your local dive shop to talk you out of it, and if they can't, ask them to guide you through it. The sights are well worth it. For further discussion on diving this coast, see the Halona Blow Hole description. Lana'i Lookout, on the South Eastern shore, is at the only parking lot South of the Halona Blow Hole and North of Hanauma Bay.

Koloa Landing6

Koloa Landing

4.6(57 reviews)Kauai, Hawaiian Islands

Koloa Landing at Hanaka'ape Bay is a very popular dive site, especially for scuba instruction. The entry is easy, and there is plenty to see to the left and right of the landing. From Lihu'i heading West on Highway 50, turn left on Highway 520 (Maluhia Road) at mile mark 6.8. After about 3 miles, you'll hit a T in the road at Koloa. Jog right and then an immediate left onto Po'ipu Road, and head South to Po'ipu. At about mile 4.8, take the RIGHT fork. After .2 mile, take the left fork. You'll see the landing in about a tenth of a mile.

Hanauma Bay7

Hanauma Bay

4.6(43 reviews)Oahu, Hawaiian Islands

What is there that hasn't already been said about Hanauma Bay? Divers' paradise, excellent diving, friendly marine life, etc. Unfortunately, the overcrowding of this popular site has caused major environmental impact and has necessitated the implementation of many conservation measures. As crowded as this place is, it now has only one-third the attendance it used to have before restrictions were passed in 1990. Parking, and access to the beach is controlled, and volunteer docents try to educate the visitors so additional damage is avoided. One of our greatest concerns is the trampling of the reef. Although numerous signs are posted, it still constantly occurs. Although there's not too much live coral inside of the reef, other living organisms inhabit the zone, and it is basic diver etiquette to avoid touching any reef. Take Kalanianaole Highway (72) East to Koko Head. At the top of the hill, turn right into Hanauma Bay.

Mala Wharf8

Mala Wharf

4.6(33 reviews)Lahaina, Maui, Hawaii

Mala Wharf (sometimes called Mala Pier) was once a fully-functioning pier which served as a shipping facility for the island’s pineapple and agriculture. In 1992, however, 30 ft. surf came marching into Lahaina as a result of Hurricane Iniki, and the end of the dock was completely destroyed. Today, the pilings from the old dock lie scattered along the ocean floor, and what was once a shipping facility above water is now a healthy artificial reef which is home to a vast array of marine life. The dive at Mala is one of the best shore dives on Maui. The dive much like a wreck or cave dive in that you can dive through and under parts of the pier. Be careful as some of the "coves" are dark and there can be debris from the pier, such as concrete rebar. The light shining through the pier is magnificent, along with the marine life. Dozens of turtles, rock fish, frog fish, white tip reef sharks, and the occasional ray can all be seen here. I have never been diving here and not seen at least one white tip reef shark. Take Front Street to Ala Moana Street (just south of Lahaina Cannery Mall). You will see signs for Mala Small Boat Ramp. Turn on this street and stay to the right. Drive as close to the boat ramp as you can and park in one of the stalls. Note that the dive site and entry is to the left of the old collapsed pier. To the right is an active boat launching ramp and harbor. It is best to dive at high tide, as the entry requires walking about 50 ft on rocks/dead reef. Once you can put on your fins, do so and swim until it drops off to about 10-15 ft. The dive is all along the collapsed pier. Mala Wharf is also known as Mala Harbor.

Shark's Cove9

Shark's Cove

4.5(80 reviews)Oahu, Hawaiian Islands

Very easy shore dive, local PADI instructors take students here for their open water cert dives. Lots of turtles, fishes... also neat swim-throughs in the reef. Nothing too nasty, maybe the occasional reef shark, though I've never seen one here. A great O'ahu dive. But it's crowded on the summer weekends... though Three Tables (another dive site) is right next door, so there's plenty of space in the water, even if parking is bad. Shark's Cove at Kalalua Point is another must-dive site for Oahu. The entry is easy, and it's just a short kick to get outside the reef. Kids and snorkelers will find the cove perfect for their activities. Rocky coastal area & tidal pools teeming with small fish for snorkeling, plus showers & restrooms. Off Kamehameha Highway on the North Shore in the Waimea area. Why is it called Shark's Cove? Because the outline of the reef from above looks like a shark. Shark's Cove is also known as Pupukea

Three Tables Beach10

Three Tables Beach

4.6(37 reviews)Oahu, Hawaiian Islands

Three Tables is great as long as you use some caution. It is a small but beautiful sandy beach with access to the best coral on the north shore. Like every spot on the north shore, this is best snorkeled in the summertime when the water is calm. Three Tables beach offers good scenery for the diver: outcropping of lava, a wall, and lava tubes.Off Kamehameha Highway on the North Shore in the Waimea area, just South of Shark's Cove.

Napili Bay11

Napili Bay

4.8(5 reviews)Lahaina, Maui, Hawaii

Entry is sandy, and the bottom is sandy with moderately steep entry and then reef further out. Sea turtles frequent the bay, and snorkeling can be fair when the surf is mellow. When the surf is up visibility, and thus snorkeling, is poor. The water is frequently glassy, but when big swells come in waves can become quite large, and the rip currents which form here pull directly out to sea. Less experienced swimmers should avoid the water here during such conditions. There are restaurants, bathrooms and a general store in the resort. There is a shopping center with supermarket between the main highway and the resort.

Hookena State Beach Park

5.0(2 reviews)The Big Island, Hawaiian Islands

We will be "hooka" diving using an inflatable boat on the big island of Hawaii this Thanksgiving, so shore entry is very important too us. We are sure some of the dive sites you have described will be visited. One beach not mentioned on your site is Hookena state beach park south of Kona. Having snorkeled there I wonder how it compares with the other sites you've reviewed. Thanks for a very good web site.

Police Beach

5.0(2 reviews)Oahu, Hawaiian Islands

Police Beach is a remote beach on Oahu's North Shore, even though it lies between other popular surfing beaches. It is not remote in terms of distance, but rather in terms of accessibility. The beach encompasses a large stretch of shoreline, all the way from Papa'iloa Beach to Pua'ena Point. To get to Police Beach, one either has to walk along the shoreline from Papa'iloa Beach or Pua'ena Point Beach Park because the backshore of Police Beach is private property. Episodes of the popular TV series LOST were filmed on Police Beach. The beach is sandy, but many areas on the water's edge are covered by a lava rock shelf. The ocean bottom offshore is rocky too, so swimming isn't possible here (also because of strong rip currents, especially when the surf is up). Several surf spots are located offshore. Also, local fishermen come here for shoreline fishing.

Horseshoe Reef

5.0(2 reviews)USA, Hawaii, Big Island

20-60 feet ~ As the name implies, this site is formed by coral reef that is shaped into a horseshoe with ledges and lava tubes below. Resident white tip reef sharks like to snooze under the ledges in the day time. Check out the swim through "the kitchen sink": You will see how it got its name when you go down the drain. Also known as Pam's Cave and Horseshoe North

Nice Dive site. Genreally good visibility. Advanced Dive. Wreck of old fishing vessel. Inside has decent amount of access, though most of it has been blocked of by local divers hoping to protect those unaware of the dangers of penetrating a wreck. Occasionally spotted eagle ray, crown of thorns (DON"T TOUCH THESE), and octopus will be around. Outside Kewalo Basin on Oahu's south shore. Sea Tiger is also known as SeaTiger.

Turtle Canyon Reef

5.0(2 reviews)Oahu, Hawaiian Islands

Turtle Canyons is a great scuba dive for both beginners or first time diving and novice divers alike. The reef is approximately 20 to 45 feet deep. The boat ride out to Turtle Canyons takes around 15 minutes depending on your boat and what harbor you depart out of. Turtle Canyons was formed thousands of years ago when volcanic activity was in action here on Oahu. Large lava/rock encrusted fingers point out from the shallow shores of Waikiki in a south eastern direction. In between these "fingers" are mostly small rock boulders , coral heads and sand. If you're really into colorful corals, this dive won't be for you. The area where this dive site is situated leaves no room for fragile corals and soft corals to flourish. Heavy swells roll in from the south east like blazing freight trains only to leave an area that almost resembles a whitish blue desert. So why the heck even bother? Well my friends, this dive is an incredible one if you want to view the Hawaiian green sea turtles in their natural habitat. We get divers with hundreds of dives who really "freak" out when they meet these calm spirited attitude laid back reptiles. You can literally swim right with these rare reptiles without a care in the world. I do want to mention that turtles are on the endangered species list so harassing or harming these beautiful creatures will leave you with a painful fine. So please give these cool marine creatures your utmost respect, after all you are in their "house."

Turtle Heaven

5.0(2 reviews)Oahu, Hawaiian Islands

This site is half the distance from Turtle Street and is inshore. The reef peaks at 10 feet below the surface and, because of seismic activity during its formation, has a valley below it that drops to a depth of 100 feet. The wall is on a vertical drop and it has a partner another 100 yards inshore. The main focus of the site is along a 200 yard section of the seaward side of the wall and its top has a wide variety of fish, corals, overhangs and arches. Small pukas are found through the side of the wall leading to Turtle Street. The characteristic valley is called the Haleiwa Trench. Another attraction is a substantial coral mound, 20 yards off the wall, which seems to be a remnant of the original structure. The pinnacle of this mound is 100 feet wide and stops 35 feet below the surface. About a dozen turtles sit on the mound and are at ease with visiting divers.

Garden Eel Cove / Manta Ray Heaven20

Garden Eel Cove / Manta Ray Heaven

4.6(20 reviews)Kailua-Kona

The dive site “Manta Heaven” is located in Makako Bay that is just around the corner of Keahole Point, the most western tip of the Big Island. It’s offshore of the Kona International Airport. During daylight hours, the dive site is called “Garden Eel Cove”. In the summer of 1999, the manta rays essentially abandoned the Kona Surf Hotel as a feeding area. There were no sightings for many weeks. James knew that he could find the manta rays somewhere along the coastline and had heard from local boat captains that manta rays were being seen during the day at Garden Eel Cove. His friends Mike Ho and Mike & Nicki Milligan had done night dives in the bay and a manta swam by.
