If you’re a certified diver heading to Oahu, the Waikiki Two Tank Guided Scuba Diving Adventure offers a compelling way to discover some of Honolulu’s most stunning underwater sights. For around $249, you get about four hours of intimate, small-group diving led by experienced PADI Dive Masters and Instructors. The tour takes you to historic wrecks like the U.S.S. Nasua and vibrant reefs teeming with Hawaiian green sea turtles, reef sharks, and colorful tropical fish. Located conveniently in Ala Wai Small Boat Harbor, this experience promises a relaxed, personalized encounter with the underwater world, perfect for those who value quality over quantity.
What we particularly love about this tour is the small group size—limited to just six divers—which means more personalized attention and fewer crowds. Plus, the fact that you can explore both deep wrecks and shallow reefs in one outing really maximizes the variety of your underwater adventure. The guides seem passionate and knowledgeable, making sure every diver feels comfortable and well-informed. On the flip side, a potential consideration is the need to show SCUBA certification at check-in, so this isn’t suitable for first-timers or uncertified explorers. This tour suits confident, certified divers who want a private, authentic experience with the best of Honolulu’s underwater scenery.

Nasua, in particular, offers a glimpse into naval history and serves as a magnet for marine creatures, making each visit unique.
Reef Highlights
After exploring the wrecks, you’ll move onto shallower, lively reefs such as Turtle Cleaning Station, Nautilus Reef, and Horse Shoe Reef. These sites are known for their bustling marine life, including green sea turtles, which are often seen cleaning themselves or munching on algae.

The Kewalo Pipe and Ewa Pinnacles are other notable spots, offering diverse underwater landscapes—from coral encrusted structures to open water pinnacles.

Gear & Certification
All dive gear, tanks, and weights are included, so you only need to worry about your wetsuit fit and certification details. The guides are clear about the need for SCUBA certification—no uncertified divers here, but if you’re new to diving, they offer a Discovery SCUBA experience separately.
