Two-Tank Night Dive Reveals Hawaii’s Underwater World from Dusk to Darkness
A custom-designed two-tank night diving adventure is giving visitors the opportunity to experience the remarkable transformation of Hawaii’s underwater world from daylight into complete darkness. Departing from Hawaiian Waters The Colony, the excursion is conducted aboard specially built Radon boats engineered for Hawaiian waters, providing a smooth and comfortable journey for both first-time night divers and experienced underwater enthusiasts eager to witness the ocean after sunset.
The first dive begins during the late afternoon while natural light still illuminates the reef, allowing participants to become familiar with the underwater environment before nightfall. As daylight gradually fades, divers observe the changing behavior of tropical fish, colorful corals, and graceful sea turtles. This unique transition period offers an unforgettable look at how marine life prepares for the arrival of night.
Once darkness settles across the ocean, the second dive unveils a completely different underwater landscape. Guided by an experienced captain and PADI-certified dive instructors, divers encounter nocturnal marine species emerging from their daytime shelters while familiar reef formations take on a dramatic appearance beneath the glow of dive lights. The contrast between the two dives creates an immersive and memorable marine adventure.
The excursion features two carefully planned dive profiles, combining expert guidance, purpose-built vessels, and exceptional safety standards to deliver a rewarding underwater experience. Whether seeking a first night dive or expanding an experienced diver’s adventures, this journey from Hawaiian Waters The Colony offers an extraordinary opportunity to explore the beauty and diversity of Hawaii’s marine ecosystem after sunset.

Customer Reviews

I had an absolutely fantastic weekend doing my orientation dive (and fun dives) with Ocean Divers at Killary Fjord! From the moment I arrived every member of staff and all the other divers were incredibly welcoming, friendly and helpful. The atmosphere was supportive and relaxed, making it easy to feel comfortable even if you’re just starting out like me (10 dives previously). There were a lot of divers, but each in small groups with their own dive master or dive instructor and grouped together in the OW/AOW courses or fun dives. While I had already done my OW elsewhere, I’ll definitely be doing the advanced course and further dives with these guys as the level of dedication and commitment that goes into making their students be successful divers is visible. Bring a bit of patience for the initial response period if you reach out during a very busy time - it‘s hard to respond when you’re always in the water 😄 but I honestly can’t recommend them enough if you’re looking to become a good diver and explore Irelands underwater world with a genuinely lovely group of people.

I’m doing the drysuit diver course with Oceandivers at the moment. I was having trouble getting my buoyancy right, so had six pool sessions to get it right at no extra charge!! What a crew Oceandivers have. There was no pressure, just take your time and get it right. Dan is always on hand to help you out and the rest of the lads are so helpful. I had my first sea dive for the buoyancy certification today off Dalkey island. It was fantastic!! The extra lessons really paid off. I cannot recommend the Oceandivers crew highly enough. It is and has been a pleasure working with Oceandivers to get my drysuit certification. Can’t wait to get back in the water with the crew!!

I got my OW course with Oceandivers in the previous two months and they are really professional and helpful. Especially, I would like to thank my instructor Alan, he is really amazing experience diver and nice advisor. Great enjoy my training with him and also thank other instructors, divemasters and staffs from Oceandivers.
