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

This experience has been on my bucket list for a while and I was so thrilled to get to finally enjoy it! We went out at 9:30 PM so it was dark! Boating out to the site off the coast was so cool, with the beautifully lit up Kona Outrigger in view. The thrill of jumping off the "perfectly good boat" into the ocean at night gave a bit of pause but we went for it and easily swam out to the floating light ladders to wait for the mantas. As we got settled in to wait the guides talked about these huge creatures we were about to see and gave some really fascinating facts and background about them. When the first manta arrived it was amazing! Watching how gracefully they move and then watch them come up close and swim by, belly up was a thrill! They entertained us with amazing rolls through the water and even occasionally brushed against us as they swam by. I think we counted 7 mantas before we were finished. This experience was so much better than I ever imagined and well worth it!

The tour was amazing. One of the coolEat experiences I have ever had. The only issue I had was having to get out of the water 10 minutes early because I ended up feeling seasick and multiple other people got sicker so you might want to take Dramamine before you go

This was a great experience! The walk up/sign in was quick and easy. Staff was prompt and on time. Quick 5 minute boat ride with a fun crew. I went solo and the staff was very welcoming. This has been the highlight of my trip so far! Would 100% recommend seaquest!

What an amazing and unexpected experience! The guides really took care of us and we felt in good hands the entire time. You could tell everyone at sea quest really knew what they were doing and were very knowledgeable!

A great experience. Amazing really! A highlight of the trip.
