Best Diving Spots in Waikiki

Turtle Canyons

Located just off Waikiki Beach in Maunalua Bay, Turtle Canyons has a sandy bottom with a depth of only about 35 to 40 feet making it especially ideal for beginners who want to master the basics although it’s a must-visit for divers of all skill levels.

As the name suggests, it’s one of the most popular places for diving with Hawaiian green sea turtles. The turtles are accustomed to divers making close encounters common while providing excellent photo ops.

You can even watch them at a turtle cleaning station, where they come for a “turtle car wash,” with small fish doing all the clean-up work.

There are also tropical fish like butterfly fish along with octopus and eels.

Nautilus Reef

A staple on shallow reef diving tours from Waikiki, Nautilus Reef (also known as Shark Reef), is one of the must-dive sites, renowned for its frequent sightings of blacktip and whitetip reef sharks.

Just a short ride from Kewalo Basin, divers of all levels can enjoy it with both shallower and deeper areas that reach up to 100 feet.

The farther south you swim, the more than reef slopes down.

Formed by ancient lava flow that’s now covered by hard coral, some say it resembles the rocky surface of Mars.

With beautiful corals and many types of tropical fish from black triggerfish to butterfly fish, along with octopus and moray eels, it provides a spectacular underwater paradise.

Horseshoe Reef

Another excellent dive site in Waikiki, Horseshoe Reef was named after its shape and is surrounded on all sides by additional reefs, making it a great spot for exploring multiple reefs.

Accessed by boat, it’s located about a quarter-mile from the Kewalo Basin and has a depth that ranges from 30 to 50 feet which means it’s suitable for divers of all types.

Expect to spot sea turtles and plenty of colorful fish while watching for camouflaged octopuses that like to hide out here.

Be sure to look into the nooks and crannies of the area’s coral shelf systems where sea turtles and whitetip reef sharks like to sleep.

YO-257

Regularly ranked among the top wrecks for diving in the U.S., the YO-257 was purposely sunk by Atlantis Submarines Hawaii in 1989 to provide a sightseeing point.

More than 35 years later, it’s become a massive artificial reef inhabited by abundant marine life attracting advanced scuba divers.

The 175-foot-long vessel lies at a depth of 85 feet and has large cut-outs that allow divers to swim through her hull and even penetrate the crew section.

In addition to green sea turtles that like to hang out here, watch for one of the visiting submarines.

Sea Tiger

The wreck of the 189-foot Sea Tiger has become another one of Waikiki’s top dive sites.

In 1996, it was sunk by a submarine company having been originally intended for drift-net fishing operations and now sits upright at a depth of 120 feet on a sandy bottom.

There hasn’t been a lot of coral growth but the vessel is teeming with marine life, including schools of fish, moray eels, and eagle rays that are often spotted circling it.

Divers can swim through the bridge, mid-ship, and cargo holes.
