Hawaii, renowned for its stunning beaches and vibrant culture, also hides a breathtaking secret beneath its turquoise waves: a collection of fascinating shipwrecks. These underwater museums offer divers and snorkelers a unique glimpse into the past, showcasing remnants of maritime history teeming with marine life. Prepare to explore these sunken treasures, each with its own captivating story and ecosystem.
Diving Deep into Hawaii’s Shipwreck Scene
Hawaii’s underwater landscape is more than just coral reefs and colorful fish; it’s a graveyard of ships, planes, and other vessels lost to the sea over the years. These wrecks have become artificial reefs, attracting a diverse range of marine animals, from playful dolphins and graceful sea turtles to vibrant nudibranchs and elusive reef sharks. Diving or snorkeling on these sites offers a truly unforgettable experience, blending history with the wonders of the natural world. Let’s take a look at some of the most popular shipwreck dive sites in Hawaii, breaking down the details to help you plan your own underwater adventure.
The YO-257 Oil Tanker (Oahu)
The YO-257 is perhaps Oahu’s most popular and accessible shipwreck dive. A former U.S. Navy oil tanker, the YO-257 was intentionally sunk in 1989 to create an artificial reef. Resting at a depth of approximately 100 feet (30 meters), the wreck is relatively intact and offers excellent visibility, usually ranging from 50 to 80 feet. Divers can explore the ship’s decks, engine room (with proper certification), and even penetrate some of the interior spaces. The YO-257 is now home to a vibrant community of marine life, including reef fish, eels, turtles, and even the occasional white-tip reef shark. Because it’s a fairly deep dive, it’s best suited for experienced divers with advanced certification.
Getting There: Most dive operators depart from Kewalo Basin Harbor or Ala Wai Harbor in Honolulu. The boat ride to the YO-257 site is typically around 15-20 minutes.
Cost: Expect to pay around $150-$200 for a two-tank dive trip to the YO-257, including equipment rental. Shore dives are generally not possible due to distance from shore and depth.
Who Should Dive It: Certified advanced open water divers with experience in deep diving are recommended. Nitrox certification is also beneficial.
Pro Tip: The current can sometimes be strong around the YO-257. Listen carefully to your dive master’s briefing and be prepared to use a reef hook if necessary.
The Sea Tiger (Oahu)
The Sea Tiger, a former Chinese freighter, was intentionally sunk in 1999 to create another artificial reef off the south shore of Oahu. This relatively large wreck sits upright on the sandy bottom at a maximum depth of about 120 feet (36 meters), with the top of the mast reaching up to around 60 feet (18 meters). This range caters to a wide range of diver skill levels. The Sea Tiger is known for its abundant marine life, including schools of fish, eels, turtles, and even larger pelagic species like sharks and rays. Divers can explore the ship’s cargo holds, bridge, and engine room, and even swim through some of the open passageways. Be aware that the Sea Tiger is often subject to strong currents, especially on the surface, making it important to choose a reputable dive operator and listen carefully to their instructions.
Getting There: Dive boats typically depart from Kewalo Basin Harbor or Ala Wai Harbor. The boat ride to the Sea Tiger takes about 20-30 minutes.
Cost: A two-tank dive trip to the Sea Tiger will typically cost between $150 and $200, depending on the operator and equipment included.
Who Should Dive It: Advanced Open Water certification is recommended due to the depth and potential currents. However, the top of the wreck is accessible to Open Water divers with proper supervision and favorable conditions.
Pro Tip: Pay attention to the current and visibility. The viz can vary on any given day, so check with the dive operator before heading out. Bring a dive light to explore interior areas of the wreck.
Mahi (Oahu)
The Mahi, originally named the USS Sentry, was a US Navy cable layer ship, later used for oceanographic research and finally sunk as an artificial reef near Waianae in 1982. The wreck sits upright in approximately 95 feet of water, with its highest point around 50 feet, making it accessible to a range of divers. Over the years, the Mahi has evolved into a rich marine habitat. Expect to see schools of reef fish, barracuda, moray eels, turtles, and even the occasional manta ray. The ship’s structure is in relatively good condition, offering opportunities for exploration and photography. The access points are easily navigable while offering plenty of marine life.
Getting There: Dive boats usually depart from Waianae Boat Harbor. The boat ride is relatively short, around 10-15 minutes.
Cost: A two-tank dive trip to the Mahi usually costs between $140 – $190.
Who Should Dive It: Both Open Water and Advanced Open Water certified divers can enjoy this wreck. Open Water divers should stay within their depth limits.
Pro Tip: Check the weather forecast and sea conditions before heading out, as the west side of Oahu can be affected by swells. Look closely for smaller creatures like nudibranchs hiding in the crevices of the wreck.
San Pedro (Oahu)
Located near Koko Head, the San Pedro, or “Mini Barge” as it’s sometimes called, is a much shallower and smaller wreck compared to the YO-257, Sea Tiger, and Mahi. This barge was intentionally sunk to create an artificial reef. You’ll find it in about 30 feet of water. While not as large or dramatic as other wrecks, the San Pedro offers a great shallow dive or snorkel site, teeming with reef fish, eels, and other marine life. The visibility is generally good, and the lack of strong currents makes it an ideal spot for beginner divers and snorkelers.
Getting There: The San Pedro is accessible by boat from various locations along the south shore of Oahu, including Hawaii Kai.
Cost: A snorkeling trip to this spot generally costs $70-100. Two-tank diving trips are approximately $120-$160. Shore dives aren’t feasible, requiring boat access due to proximity to deep channels and currents.
Who Should Dive It: This is suitable for all levels of divers and even snorkelers.
Pro Tip: Bring an underwater camera to capture the colorful reef fish and the small yet thriving ecosystem around the wreck. This is a great spot for practicing your buoyancy skills.
The Corsair Airplane Wreck (Oahu)
While technically not a shipwreck, the Corsair airplane wreck is a must-see for divers visiting Oahu. This WWII-era fighter plane crashed during a training exercise in 1948 and now rests on the seabed at a depth of around 105 feet (32 meters) off the coast of Sand Island. The Corsair is a relatively small wreck, but it’s remarkably well-preserved, offering a fascinating glimpse into aviation history. The plane is covered in marine growth and attracts a variety of marine life, including goatfish, eels, and the elusive Hawaiian monk seals. Due to its depth, this dive is recommended for experienced divers with advanced certification.
Getting There: Dive boats usually depart from Kewalo Basin Harbor or Ala Wai Harbor. The boat ride to the Corsair site takes about 15-20 minutes.
Cost: Expect to pay around $150-$200 for a two-tank dive trip to the Corsair, including equipment rental.
Who Should Dive It: Certified advanced open water divers with experience in deep diving are recommended.
Pro Tip: The current can sometimes be strong at the Corsair site. Be prepared to use a reef hook if necessary. Be respectful of the wreck and avoid touching or removing anything.

Snorkeling Among Sunken Secrets: Bringing Shipwrecks to the Surface
While many shipwrecks in Hawaii are best explored by scuba diving, there are a few shallower sites that are suitable for snorkeling. These sites offer a fantastic way to experience the thrill of exploring a shipwreck without the need for scuba gear. The San Pedro barge, as mentioned above, is a good option for snorkelers. Before heading out snorkeling always evaluate the conditions and be familiar with the area.
Beyond the Boat: Shore Diving Possibilities
For divers who prefer to skip the boat ride, there are limited shore diving opportunities near some of the wrecks. While you generally want to take a boat to these dives, some dives are possible by shore. These will often be the smallest wrecks. Check local dive guides and shops for guidance, and ensure you are well-prepared for any potential currents or surf conditions.
Underwater Etiquette: Respecting Hawaii’s Sunken Heritage
When visiting any shipwreck site, whether diving or snorkeling, remembering the importance of underwater etiquette is vital. These wrecks are more than just piles of metal; they’re historical artifacts and unique ecosystems. Follow these principles to ensure their preservation for future generations:
No Touching:
Refrain from touching anything on the wreck. The oils from your skin can damage delicate marine life and contribute to the degradation of the structure.
Good Buoyancy: Practice good buoyancy control to prevent accidentally kicking up sediment or damaging coral. A stable diver is a responsible diver.
Leave No Trace: Do not leave anything behind, including trash, equipment, or souvenirs.
Observe From a Distance: Give marine life space and avoid harassing or feeding them. Observe their natural behaviors without interfering.
Report Damage or Vandalism: If you notice any damage to the wreck or signs of vandalism, report it to the local authorities or dive operators.
Respect Markers and Guidelines: Obey any markers, buoys, or guidelines that are in place to protect the wreck site.
Photography with Care: If taking photos, be mindful of your surroundings and avoid using strobes or flashes too close to marine life.
Capture the Memories: Photography Tips for Shipwreck Dives
Underwater photography allows you to capture the beauty and history of these wrecks. To achieve the best results:
Use a Wide-Angle Lens:
Shipwrecks are often large, so a wide-angle lens will help you capture the entire structure.
Get Close: Get as close as possible to your subject to reduce the amount of water between you and the wreck. This will improve clarity and color.
Use Natural Light: Whenever possible, use natural light to illuminate your subject. This will produce the most natural-looking colors.
Use a Strobe or Flash: In deeper water or low-light conditions, use a strobe or flash to add light and color.
Shoot Upward: Shooting upward towards the surface can create dramatic and visually appealing images.
Include a Model: Including a diver in your photos can provide a sense of scale and add interest to the composition.
Edit Your Photos: Use photo editing software to enhance the colors, contrast, and sharpness of your images.
Practice Makes Perfect: The more you practice underwater photography, the better you will become.
