Underwater Cave

Electric Beach

Electric Beach is an awesome dive teeming with turtles, Spotted Eagle Rays, eels, Lizardfish, Parrotfish, Pufferfish, and many other species. Wildlife is drawn to the warmer water within 100 yards of the shore being circulated through the area by a nearby power plant. This is a relatively shallow site, and is a great spot for photography.

Shark's Cove

Shark coves has been rated # 1 and ranked #2 Shore Dive in the world by Scuba Diving Magazine (July 2005). These caves and caverns were formed by lava flows. In addition to sharks, on any given day you are likely to see turtles, Angelfish, Bigeyes, Blennies, Boxfish, Butterflyfish, Eels, Peacock Groupers, Hawkfish, Lizardfish, Parrotfish, Pufferfish, Spotted Eagle Rays, Scorpionfish, Snappers, Squirrelfish, Surgeonfish, Tangs, Triggerfish, Trumpetfish, Unicornfish, Wrasse and Yellowfin Goatfish.

The Firehouse

This unforgettable dive site is the best way to access “The Cathedrals” from shore. Formed by 2 huge lava arches that rise out of 45’ of water, “The Cathedrals” is a magical place filled with Angelfish, Blennies, Boxfish, Butterflyfish, Eels, Peacock Groupers, Hawkfish, Lizardfish, Parrotfish, Pufferfish, Snappers, Squirrelfish, Surgeonfish, Tangs, Triggerfish, Trumpetfish, Unicornfish, and Wrasse.

Haleiwa Trench

This very interesting dive site was created when the military blasted a narrow slot out of the lava rock, creating a trench just wide enough to hide a submarine among the nearby reefs.

Spitting Caves

Spitting Caves is one of the best drift dives on Oahu. Located along China Walls, it is a great place to catch a glimpse of the endangered Hawaiian monk seal. Whitetip reef sharks, eagle rays, large eels, frogfish, and turtles are also common here. During winter months, you can hear whale songs echo off the cave wall and may get the amazing chance to see a mother whale and her calf.

Sea Caves

The Sea Cave is an exciting cave dive. The mouth of the cave is located in 55 feet of water, and the cave extends inward approximately 150 feet. Whitetip reef sharks, sea turtles, and many different types of shell and reef fish can be found within. After exploring the large cave, divers drift along the wall with the current.

Fishes Next To Coral

Turtle Canyon

This Waikiki dive site is one of the best places to see turtles. You can expect to see several large turtles on your dive. They rest on the bottom or on the reef ledges that extend over the sand. These turtles are used to divers, giving you a great opportunity to get close and take a picture while doing your Shore diver Specialty certification. The reef overhangs host a variety of critters and are worth exploring with a dive light.
