Diving with Manta Rays on the Big Island of Hawaii


The Big Island of Hawaii is a world-famous scuba diving destination, and a night dive with the manta rays is a must-do while on the island.

Among the three manta ray feeding stations, the site by the Sheraton Kona Resort Hotel is the most popular one. The shore dive started by the rocks and surf that sometimes made entry and exit challenging.

A short 10-minute dive over a shallow 20-feet (6-meter) deep reef led to the feeding station.

The coral was unfortunately dead due to recurring mooring activities, but we could rest there and hold our position against the potential surge that rocked us in all directions.

Sea urchins covered the reef; we had to be careful not to stick our fingers or any part of our body on any of these.

A Manta Ray Dive on Big Island is also a night dive adventure, making the experience twice as thrilling! After reaching the site, the divemaster set several dive lamps to attract the plankton, which in turn attracted the manta rays.

Shortly after setting the underwater lamps, small flashes of white appeared in the dark waters, increasing in size by the second. Soon the massive wings of the manta rays came in full view, as the gentle giants surrounded us in the artificial lights.

For about 40 minutes, we witnessed the dance of the manta rays.

They tangoed, swirled, and twisted around us. Fearless, they softly touched us with the tip of their wings. So gentle we first thought it was a dream. But so real as they repeated the same tap over and over again.

As I followed one of the manta rays swimming by, I turned my head back and suddenly faced the full open mouth of a giant manta. So large I thought it was going to swallow me whole.

For a second or two, I froze and held my breath, fearing my time was up. But the manta rays only care about plankton, and the open mouth just scraped by me. What an intense moment!

I had not expected manta rays to be so large. They were an impressive sight, with most with wingspans reaching about 15-18 feet (5-6 meters). And when three or four of them danced around us, the spectacle was magical.

Especially as the giant beasts only feed on such tiny plankton.

Watching manta rays is better done scuba-diving, but snorkeling is another good option. Several snorkelers would free-dive from the surface, enjoying their time snorkeling with manta rays as well.

As we returned slowly to the shore, we passed by other fascinating marine life. An unusual green crab with green spots, a white-and-black conger, unexpected encounters in the dark waters.

The exit was more challenging than the entry as the surf kept pushing us on the rocks, especially more so as we felt tired from the dive.

What an experience we had! A manta rays night dive is a one-in-a-lifetime experience, and a must-do while on the Big Island.
