Kona Manta Ray Night Dive – Hawaii – Big Island

Site Overview

The Kona Manta Ray Night Dive is widely regarded as one of the most extraordinary wildlife encounters on Earth, where giant Pacific manta rays with wingspans up to five meters perform graceful barrel rolls within inches of divers attracted by plankton illuminated under powerful dive lights. This iconic experience occurs nightly off the Kona coast at sites including Keauhou Bay, Garden Eel Cove, and Manta Village where mantas are resident year-round. Divers kneel on the ocean floor while lights attract dense plankton clouds that draw the massive rays in aerial ballet displays. The encounter is profoundly moving and has been featured in countless documentaries and nature programs bringing divers from around the world to witness this spectacular natural phenomenon. The manta rays off Kona are individually identified by researchers using their unique belly spot patterns allowing long-term monitoring of the population. Some individual mantas have been documented visiting the cleaning stations for over twenty years demonstrating remarkable site fidelity. The nightly feeding aggregation represents one of the most reliable large marine wildlife encounters available to recreational divers anywhere in the world. Local dive operators follow strict guidelines ensuring minimal impact on the manta ray behavior while providing divers with unforgettable close encounters with these gentle giants.
