Full description

Experience an exciting 75-minute nighttime snorkeling expedition. Get up close and personal with stunning manta rays as they gracefully soar through the water. Your underwater adventure will take place in clear warm waters near protected reefs abundant with marine life.  

After the sun sets, head off into the nighttime waters to see a fascinating "manta ray ballet" along the Kona coast near the mouth of Keauhou Bay. This point of departure is one of the island’s most successful and consistent manta ray viewing locations. Your snorkeling guide will outfit you with all the necessary gear needed to embark on your experience including snorkel gear, wetsuits, and flotation devices. After a quick safety briefing, plunge into the dark waters and be captivated by these graceful creatures as they feast on plankton.

Grip onto the flotation swim ring with high-illumination blue water lights that attract the plankton on which the mantas feed. Soon afterward, rays will glide through the water almost at arm's length opening their enormous mouths to feast.

After your remarkable underwater adventure, return to your boat and warm up with a nighttime snack of hot chocolate and cookies

Seeing the Manta Rays is something we will never forget! What a unique and very cool experience! As for the company- there were several things they could improve on. One is providing more details about what to expect before you get there. It was all very rushed and confusing. They should have a detailed informational video or something explaining the process for loading in the boat, what to do once you're at the site, and the process for returning to shore. Many of the staff seemed uncertain as to what they were supposed to do. Our party of 4 felt more like we were being herded from one place to the next, rather than having the inviting and warm experiences of activities we participated in while visiting HI. It seems that the time they tell people to arrive isn't quite enough to get everyone ready to go, so it felt very rushed. Perhaps we were there on an off night or something. Of course the Manta Rays were the highlight and they were awesomely wonderful! Go if you can!!

The manta ray snorkel was the highlight of our Big Island trip. We had quite the showing and they seems to be doing tricks for us, inches from our faces. The crew was fantastic. Thanks!
