More ways to explore the area's outdoor wonders
The evening air on Kona’s harbor tastes of salt and warm lava rock as the boat slips away from shore and the shoreline lights recede. Below, black water becomes a theater: lights suspended from the stern attract plankton, plankton draw mantas, and soon silhouettes begin to glide — wide-winged shapes that circle and feed with deliberate calm.

History
The Kona coast’s maritime use dates to Hawaiian voyaging traditions; modern manta dives grew from local guide observations and scientific interest in the late 20th century.
Conservation
Operators emphasize no-touch policies, limited numbers in the water, and educational briefings; use reef-safe products and follow guides to minimize disturbance.

Bring a fitted mask
A well-sealed snorkel or dive mask keeps seawater out during long, still floats—rentals can fog; bring anti-fog or a mask strap.
Respect light rules
Follow guide instructions on dive lights—bright beams can disorient mantas; use lights only when directed.
Wear a thin wetsuit
A 3mm full or shorty provides warmth and buoyancy without overheating in Kona’s night water.
Prepare for boat motion
Take motion-sickness meds before boarding if you’re prone—the night ride and swell can be lumpy.
Mask & snorkel
A snug mask and simple snorkel keep your view clear during night floats.
3mm wetsuit or vest
Thin neoprene gives warmth and slight buoyancy in Kona’s night water.
Dive light (for divers)
Used under guide direction to navigate and signal; avoid shining at animals.
Reef-safe sunscreen
Protects skin pre- and post-activity while minimizing harm to coral ecosystems.
