Big Island: Eco-Friendly Twilight Manta Ray Adventure

1. Big Island: Eco-Friendly Twilight Manta Ray Adventure

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

A once in a lifetime experience! Lots of Manta Rays, the guides were great and gave lots of interesting facts. I got cold, even with a shorty wet suit and a long sleeve rash guard underneath. Your arms will get tired as well but all worth the chance to spend a bit of time with such magnificent creatures. If you are prone to sea sickness, take the necessary precautions.

Once in a life time experience you don't want to miss when you visit the Island. my 29 week pregnant lady and I floated along the manta rays and we had the blessing that a Monta ray touched the belly like sensing the double heart beat of my wife and baby. The cherry of the cake was a heavy rain over us while floating that made the experience more exited!

Had a great snorkling day. Capt choose good reef locations, protected, calm clear waters. Capt provided good facemasks, snorkle, and fins. Ladder on boat made getting back into the boat easy. The boat had comfortable seating. Good adventure. Thanks Capt !!!

The manta rays were dancing a few inches from us, it was very emotional. The crew is really professional and friendly and made us feel safe at all times. I recommend everyone to have this wonderful experience!

The boat drive is only 5min and you don‘t have to take any superprep for sea sickness. It‘s amazing to see these special creatures right next to you and it was a real highlight on this vacation for us!
