This is the most amazing experience! I highly recommend Hang Loose for this experience. The captain and crew were great, very nice and eager to help anyone needing it. The boat is comfortable. A quick rinse under a hot shower when exciting the water was so nice. But the mantas…it was so beautiful.

Hang loose was amazing highly recommend to anyone. They went above and beyond to make sure we had a great experience.
Mixed for sure!
Zachary_C, Apr 2024
While the boat staff was friendly, they were borderline dangerous. No life vests for small children in rough seas. Drove very fast with the boat listing hard (a lot of screams!) the Mantas were worth it!!! But this outfit is best for a frat party not family with kids.

Absolutely amazing! Manta Rays were beautiful, and crew was awesome!! Thank you for this great experience!!
A not-to-miss experience
Erin_W, Apr 2024
Wow, what an amazing sight to see! Getting to see manta rays so up close and personal (some literally swimming directly beneath your body) is an experience that is not worth missing. The boat ride out to the area where we got to snorkel with them was a bit choppy, but definitely worth it. I appreciated that the crew stayed nearby in the water and kept checking in, in case anyone needed anything. I think it would have been helpful to have the noodles for our feet earlier so that getting in the snorkeling position would have been easier. It's important to be mindful of how close the mantas swim to the surface so as not to accidentally touch them, particularly when getting into the snorkel position.
Mantas in paradise
Dan_R, Apr 2024
Mind blowing. All we're amazed. Nothing like it anywhere. A unique encounter that cannot be duplicated. Book it!
Unforgettable experience!
Alona_M, Apr 2024
We had the best time, manta rays were so close to us and so magnificent! Would love to come back again!
John_C, Apr 2024
Captain kept it upbeat and fun. They made sure to put us on a perfect location. Must do while visiting Kona.
An Amazing Experience
Carolyn_H, Apr 2024
What an amazing experience! Watching the manta rays glide through the water circling and dancing below as they scooped up food was unbelievable. Guides were friendly, informative and helpful. We have done a scuba diving trip to see the manta rays in the past and we are so glad we snorkeled with them too. Both were unbelievable and well worth it.
Amazing Crew and Experience, Motion Sickness Warning
Staci_M, Apr 2024
This is a once in a life time mind blowing experience. For anyone unfamiliar, Manta Rays are larger, safer, and friendlier than you think. Simon, Noah, Danny and Vincent are super hospitable and fun and make the experience amazing. My only warning, if you’ve ever experience motion sickness or are new to boats take a Dramamine the night before and day of this, the rocking of the boat is pretty brutal. You don’t have to actually be able to swim long distance or float (my husband doesn’t float well) but it is best for you to be comfortable in the water before signing up as you will be floating on the surface using upper body strength to a degree.
Peter_B, Apr 2024
Having giant creatures swim up and then slide gracefully by us was amazing; a sight unlike no other. Our night on the ocean was magical
Up close with mantas!
Susan_C, Apr 2024
Bryce, Ryan, and Avery made sure that we had a great experience! The captain greeted us as we arrived and the crew helped us with our gear as we loaded onto the boat. We zipped across the ocean (great music!) and arrived where a couple of boats had already unloaded their passengers. We got a sneak peek of what to expect and we saw our first mantas from a distance. Instructions were clear and we were out on the water floating in no time. It took about 10 minutes for the first to appear under our lights and they were huge! I was on the end and loved the experience there because they turn up to scoop the krill and I could see straight down their mouths!! The mantas come very, very close to you and even brush against you. Excellent experience.
Wonderful experience! Would do again.
Matt_S, Apr 2024
The crew were friendly, helpful and knowledgeable. We were able to see lots of manta rays and enjoyed every minute.
