Boat-dive remote Hilo reefs on a guided 2-tank trip
4 hours
Two tanks, weights, guide
Head out by boat to remote dive sites around Hilo Bay and the Hamakua Coast on a guided two-tank tour for certified, experienced divers. Explore volcanic topography like pinnacles, canyons, and lava tubes on boat-only sites.
You must be a certified diver with at least 15 logged dives and be able to swim and use a snorkel or regulator. If your last dive was more than 2 years ago, schedule a refresher course before booking. After a two-tank dive, wait at least 18 hours before ascending above 2,000–2,500 ft.
Cancel 48+ hours in advance for a full refund. Late cancellations and no-shows are non-refundable. If the operator cancels (for example due to weather), you receive a full refund.
Join if you are a certified diver with at least 15 logged dives, you can swim, and you can use a snorkel or regulator. Minors ages 15 and under must dive with an adult. You also need to understand detailed instruction in English and carry 50 lbs of equipment unassisted.
If your last dive was more than 2 years ago, schedule a refresher course before you book.
Bring your certification card, reef-safe sunscreen, a swimsuit, and a towel. Bring a camera if you want. If you are prone to seasickness, take motion sickness medicine before you arrive so it has time to take effect.
Hilo Ocean Adventures shines when it comes to their instructors and guides, who consistently earn glowing praise from visitors. Shayna, a PADI-certified Master Scuba Diver Trainer, gets mentioned repeatedly for making both beginners and experienced divers feel confident and comfortable. Other guides like Morgan, Alex, and Aulki also stand out for their knowledge, patience, and genuine enthusiasm. The staff accommodates solo travelers and small groups without hesitation, often personalizing tours when group sizes are minimal. The marine life around Hilo delivers too—multiple turtles spotted within minutes, beautiful reefs, and memorable underwater encounters. The operation offers variety beyond diving, including kayaking, paddleboarding, and snorkeling trips around Hilo Bay and beyond. Equipment rentals receive positive marks overall, though there's mention of some aging gear like fin straps. One review noted a particularly rough day where safety concerns and operational issues converged, though this appears to be an isolated incident during challenging surf conditions. The front desk staff, including Natalia, earns appreciation for being welcoming and helpful with scheduling. Most visitors leave calling their experience a highlight of their Big Island trip.
My wife and I went for the sunset cruise and had a great time. The ocean views were fantastic and the crew were friendly and outgoing. They told us about the area and about the fishing in the area. I would do this again and hope to soon. I highly recommend them. Thanks for a great evening.
