This was probably one of the best experience in my life. Snorkeling above the giant manta in the ocean is something unique that I strongly recommend. The manta were so close to our face and body, performing amazing evolutions while catching the plancton right in front of us. It looked like a dance and there were so many of them that we lost count at some point.
Captain Bill was very professional and his boat is neat and well equipped, and has a special light set underneath that attact more plancton, and therefore more manta, than the other boats in the bay. Shauna on the deck was very professional too, and gave us plenty of advices on how to behave in the water around the manta, to make sure that they weren't hurt or scared. By following the crew instructions, we had the best experience, and when the sky is dark, we could still see very well the white bellies of the manta, that seem to be glowing of their own light when illuminated by the magenta lights of the boat and floating board.
I recommend this company among others because even if relatively new, they have precise rules and techniques that guarantee a complete success. For example, we were out in the ocean before anybody else, so we could catch the best spot in the bay (first come first served). The boat is brand new, therefore even if we had to wait a bit longer before jumping in the water, it was super comfortable enjoying the sunset eating fresh Hawaiian pineapple.
Oh, and by the way, Captain Bill makes awesome home-made cookies, so you can fix your jaws after biting on the snorkles :)
Go for it guys, you will have the best time in Hawaii !!!
P.S. I am not adding photos or videos because I believe this is an expericen to be lived rather than recorded, so I don't want to spoil this opportunity.
