Reviews: Kona Manta Ray Snorkel Tour Guaranteed or come again free
Guest User2026-02-11
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!!!

Try scuba diving was amazing. My childhood friend and I had never gone scuba diving before. No experience needed; just simple swimming fundamentals. Faith and John have a great first time scuba experience for all. A must do if in Oahu, Hawaii. Faith was the best! Super kind, extremely helpful, and caring. Really made the whole experience a blast and a memory to last a lifetime. Thank you so much Faith. You are the best! Mahalo 🤙🌺😎

Reviews: Oahu: Swim with Dolphins on the West Coast
Guest User2024-07-07
Mother Nature wasn't so cooperative on our dolphin swim, but that did not stop the crew from delivering an awesome experience none the less. We got to see a bunch of dolphins, but due to the wave conditions the swimming part proved too difficult. The crew really did try their hardest, but they can't control the ocean. We did get to see a monk seal enjoying its octopus, and striking a pose for pictures. They did take us to a cove where we got to snorkel. We saw Spinner Dolphins, Honu, and various types of fish and sea urchins. They fed us a delicious lunch of rice, pork ,and sweet potato. All of the crew made this an amazing experience, especially for the kids. They were engaging, and we had the best time we could imagine. I really can't recommend Indigo Ocean enough! It was worth every penny and then some! If/when we're back in Oahu, I won't hesitate to book with Indigo Ocean again. All photo credits to Dave Rigaud. Insta: @lwdave
