If you’re a certified diver craving an adventure in Hawaii’s waters, this two-tank dive from Waikiki offers not just a chance to see marine life but to explore a historic shipwreck right off the coast of Oahu. For $229 per person, you’ll spend roughly five hours with a professional guide, visiting the Sea Tiger, YO-257, or San Pedro wreck, followed by a reef dive along Waikiki’s shoreline. This experience appeals especially to those with Advanced Open Water certification or equivalent experience, eager to combine a wreck exploration with a vibrant reef encounter.

The guides’ reputation for professionalism and friendliness shines through in reviews, making this an experience that feels both safe and enriching.

The Itinerary Breakdown
Your morning begins early—be ready to check in at 424 Nhua St, Honolulu, by 6:30 am—a time that might seem early, but it guarantees your group beats the crowds and makes the most of the calm morning waters. The boat departs from Waikiki, setting off on a smooth ride where you’ll get glimpses of the coast before slipping beneath the surface.
The first stop is almost always the shipwreck, offering a fascinating glimpse into maritime history. You might explore the Sea Tiger, YO-257, or San Pedro wrecks, all of which are celebrated for their marine life and the thrill of seeing a submerged vessel up close. As one reviewer enthusiastically put it, “Sea Tiger Wreck was pretty amazing to see,” and many mention the bountiful fish and turtles that grace these sites.
Following this, there’s a surface interval—a chance to relax, hydrate, and discuss what you’ve seen—before heading to a reef along Waikiki’s shoreline. Here, you’ll experience a vibrant underwater community of turtles, eels, colorful fish, and even the occasional shark, as some divers have enjoyed. The reef offers calmer waters compared to the wreck site and a chance to spot marine life right off the beach.
The Wrecks: Why They Matter
Diving on a shipwreck isn’t just about seeing a sunken vessel; it’s about connecting with a piece of history. These ships, like the Sea Tiger or YO-257, have become artificial reefs, teeming with marine life, and are a favorite among divers for their visual drama and the stories they hold. Reviewers often mention how the wrecks left a lasting impression, with one describing the sea tiger as “pretty amazing to see.”
The Reef Dive
After exploring the wreck, the reef is a stark contrast—calm, colorful, and alive with fish, turtles, and invertebrates. It’s a wonderful way to wind down your dives, soaking in the vivid scenery and perhaps spotting a turtle swimming right past you. Many reviews highlight the quality of the marine life, with divers often mentioning seeing turtles, eels, and a variety of fish.
Guides and Equipment
What truly elevates this tour is the professionalism of the guides. They’re praised for their knowledgeable, personable approach and for making sure everyone feels safe and prepared. One diver remarked, “The dive masters Ron and April made both dives easy in and out of the water,” emphasizing how good guides can turn a good experience into a great one.
All equipment is provided, and it’s described as good quality, which means you can focus on enjoying the experience rather than worrying about gear. If you prefer a more exclusive experience, private instructor options are available, which some reviewers find worth the extra cost.

Practical Considerations
Remember, this is a certified diver experience. You’ll need to provide proof of certification, and you won’t be able to participate if your certification is not current or if you haven’t done deep dives (~100 ft). Also, don’t plan to fly within 18 hours of diving, as this increases risk due to pressure changes.
The tour is not aimed at beginners—the dive site conditions and equipment handling require a certain level of experience. Group sizes are small (max 16), ensuring you get personal attention, but it’s important to be comfortable managing your gear and communicating with guides underwater.
Why This Tour Represents Excellent Value
Compared to other water-based activities in Waikiki, this tour offers a unique combination of history, marine life, and professional guidance at a reasonable price. The all-inclusive package of gear, snacks, and water helps eliminate extra costs, and the small group size fosters a safer, more personalized experience.
The reviews underscore the high quality of guides and the diversity of marine life—many mention turtles, sharks, and abundant fish. The wreck sites are considered “pretty amazing”, providing a memorable and visually stunning experience that feels both adventurous and educational.
Who Should Book This Tour?
This experience is ideal for certified divers seeking an authentic wreck and reef adventure. If you’re comfortable deep diving (~100 ft), enjoy exploring maritime relics, and want to see Hawaii’s underwater treasures with knowledgeable guides, this tour will suit you well. It’s also perfect if you prefer small groups and a well-organized, safe environment.
However, if you’re not certified or are new to diving, you’ll want to consider other options, perhaps introductory dives or snorkeling tours. Also, if your medical history includes conditions like asthma or heart issues, consult your doctor beforehand—medical clearance might be necessary.
