What to Expect

This guided two-tank boat dive explores two of Oʻahu’s premier underwater sites, typically pairing one deep wreck with a shallower reef. Departing from Kewalo Basin Marina, just a short drive from Waikiki hotels, you’ll gear up for an expertly led dive with a seasoned local instructor in groups no larger than six divers per guide.

After check-in and a thorough dive briefing, you'll head out by boat to the first dive wreck site. Expect depth, clear visibility, and history as you descend alongside towering hulls and cavernous cargo holds. Between dives, enjoy surface interval time on board with water and light refreshments. The second dive is typically shallower, focusing on coral-rich reefs teeming with life and color.

From ghostly sunken warships, WWII planes, wrecked fishing trollers, to bustling turtle cleaning stations, each dive showcases a different side of Honolulu’s thriving underwater world. The entire experience is structured to maximize safety, personal attention, and unforgettable encounters with marine life.
 

Dive Sites

SEA TIGER - 80 to 130ft/25-40m

• This is an advanced dive as it claims the title for deepest recreational wreck on the island. Located about 1 mile offshore, the wreck is 165' long and about 40' wide. Originally a Chinese trading vessel named Yun Fong Seong No. 303, it was seized in the early 1990s by the U.S. Coast Guard for carrying 93 illegal immigrants. The vessel was later purchased by a dive company and intentionally sunk in 1999 to create an artificial reef. However, shortly after the company closed and the site quickly became a must dive for locals and visitors. Large schools of pyramid butterflyfish, massive sea turtles, and white tip sharks frequent this wreck. It's relatively intact structure allows divers to explore various parts of the ship, including the cargo holds and engine room.

YO 257/SAN PEDRO - 60 to 100ft/18-30m

• Enjoy this 2-for-1 special! Two unique shipwrecks sit only about 100ft/30m apart. The YO-257 is a former Yard Oiler (YO) built for the U.S. Navy in the 1940s to refuel ships at sea was sunk in 1989. The San Pedro is a Korean fishing vessel that was also intentionally sunk in 1996. When the conditions are just right, you can see the other wreck off in the distance. Great coral reefs share the decks with large numbers of fish and several species of eels. These sites were both sunk by Atlantis Submarine company to be an artificial reef, and they still frequent the area. If your lucky, you will see the long white sub pass around and between the two wrecks. Don't get too close!

TURTLE CANYON -15 to 30ft/5-10m

• Its in the name! As many as a dozen green sea turtles can been seen together here. Take a knee and watch one of the busiest turtle cleaning stations on the island. Several at a time gather to have their shells cleaned by tangs, wrasses and other fish. The turtles are used to divers, so getting a photo with one is usually easy. Don't touch though, these guys are protected by law.

NAUTILUS REEF - 30 to 60ft/10-18m

• A great example of Hawaiian hard corals create a nice elongated reef. One of those rare dives where white tips can almost always be found resting under lava rock ledges. Massive yellow margin moray eels, leaf scorpionfish, and octopus are also common

HORSESHOE REEF/KEWALO PIPE - 40 to 65 ft/12 - 20m

• Another south side double whammy! Horseshoe reef gets its name from its shape. Here you can find several species of eels, pincushion starfish, and antler coral. Swim 50ft/15m to Kewalo pipe. Keep your eyes peeled for spotted eagle rays off in the distance, and follow along this drainage pipe covered in coral and little critters galore.
