Wonderful snorkeling! Had the best time with the kids snorkeling in the bay, going off the slide and even treated to a yummy lunch and snacks. Would do it again!

Omg this was one of the most amazing experiences. I highly suggest you fo with this comoany. Everyone is super chilled and nice. I love that it was onky a 3minute trip out to sea versus some of the others beinga 1/2hr, if you get sea sick definitely go with this one. We took our 4 kids ages 8 to 19. We also seen a SHARK in the depths below. The crew was well educated and very helpful with everything even though we got a mix up in our reservation. Very accommodating and 100% worth the money..... this is a MUST DO!!!

Mahalo Mahalo Mahalo to Team Poseidon! The most amazing 4 hrs at Oahu's western coastline. We were able to see a pod of spinner dolphins within 5mins of cruising. After a while, we were informed of spotting pilot whales by the direction we are heading to, we had the 1st/2nd jump off the ocean and they say these massive creatures (big in size after orca's) seldom show up. The crew ---Elena, Traviz, Hayato, Brooke, Abby, Jerome, Shanty and Matt (i hope i got all their names correct) were all professional, guides and helps you all the way, and keep everyone safe and ensures to enjoy every moment onboard. They feed you infos that are all useful, please listen on the safety instructions and ensure to respect the wildlife. Don't bring bananas, as they have this superstition that it will bring bad luck onboard. 3part will be the snorkeling, see the turtles and colorful fishes as well as enjoy other water activities such as the paddle boards and water slide. thank you for this wonderful experience Clap clap clap!!!
