The manta rays were AWESOME!! This is truly an unforgettable experience and you have to do it while in Kona.

Fantastic crew! Great experience. I’m so glad I met this outfit

Took this tour with my wife and it was just AMAZING ! An experience of lifetime. We are non swimmers and had no prior snorkeling experience but Casey made it possible for us. She helped, guided and inspired us so well that we enjoyed the 30 minutes in water. We saw in total 13 rays ! Wouldn’t have been possible without Hawaiian Coastline Adv. ! Highly recommended as I am sure they are the BEST.

What a great adventure. Indescribable, you have to experience it for yourself. This is a not to be missed adventure run by a professional company.

Fantastic experience! Loved every minute. Beyond description, you have to do it yourself. Professional company, a lot of experience, and very efficient.

Fantastic experience we will never forget! The Rays were beautiful and it was so fun to see them and learn about them in their natural habitat. We even got to know their names. They come up close and personal which was unbelievable!! The guides and captain were great and let you know exactly what to do to be safe and to keep the Rays safe! Do not miss this tour : )

What an awesome experience. I am not much for water (as my hubby is) but i am glad i went. We saw 8 different rays ages 3-55. Fantastic. They get so close!! They bump in to you so gracefully. lol. We were originally booked on the 7:15pm tour, but were rescheduled to the 5:45pm tour. Im glad we went earlier because i was getting cold being in the water.. even with a wet suit.

They were spectacular. Great trip. If you are going to do this, go with them. Small group, professional, safe, made sure everyone was ready to go. I can’t say enough positive things about the experience with them.
