Ride a 48-passenger submarine from Kailua-Kona to explore a 25-acre lava-formed reef 100 feet below the surface. This 45-minute underwater tour combines close-up marine viewing with live naturalist narration and easy logistics from Kona Beach.
More ways to explore the area's outdoor wonders
The boat slips away from Kona’s shoreline and the island’s heat gives way to a cooler, salt-stung breeze as the shuttle pushes out to the dive site. Guests transfer to a 48-passenger Atlantis submarine, descend roughly 100 feet, and watch sunlight fracture across an 18,000-year-old lava-formed reef. Inside the viewing dome, fish thread through coral towers while eels and parrotfish inspect the slow-moving visitors.

Arrive early for check-in

Passengers must ascend/descend a near-vertical ladder; wear closed, grippy shoes and be ready to support small children.
Protect your camera from reflections

summer
Light windbreaker
Shuttle boat rides can be breezy; a thin jacket cuts wind and holds off sea spray.
winter
Motion-sickness medication or patch
Helps prevent nausea during the shuttle and while boarding the submarine.
Compact camera or phone with good low-light capability
Windows can be reflective; close, steady shots work best for reef photography.
