Reviews: Oahu Catamaran Snorkel Tour: See Turtles 100% Guaranteed
Guest User2026-09-19
We had a great time on the sea turtle snorkeling tour! The weather was beautiful, and we were lucky enough to see sea turtles. The captain and safety crew were very friendly and helpful, which made the experience even better. Our family really enjoyed the tour, and I would highly recommend it to other families visiting Hawaii!

Reviews: Waikiki: Turtle Canyon Snorkel Adventure on Oahu
Guest User2025-05-31
I booked this the night before and was happy with the experience. The guides were attentive and there were snack! We spent a considerable time looking at the dolphins and swimming around the turtles. Nice activity to do if you're looking for quick things to do in Oahu.

Reviews: Shark cage diving experience in Honolulu, Oahu North Shore | English join-in tour※
Guest User2026-09-30
The waves were too big when we went out to sea, and the waves were also huge when we went down into the harbor. It's super easy to get seasick. If you get seasick, I wouldn't recommend it. It's really tiring. There was no photo service either. I was hoping to pay extra to have staff take photos on the boat, but there wasn't. The staff said their camera equipment was broken. They offered to let us take photos on the boat with our phones, but the staff said they couldn't do it unless they had to check the boat. I felt like they could have taken photos for us, but it was a wasted trip. We didn't see many sharks in the water, and with the waves so big, it was difficult to see them. The whole experience was bad unless you're absolutely seasick and bring your own camera equipment.

Reviews: Oahu Dolphin and Snorkel Tour with Waikiki Pickup & Lunch
Guest User2026-01-01
Our family of four joined the Dolphins and You 3-hr tour in December 2025 and we had a blast! All staff members made the experience so enjoyable. Tyler was the bus guide and his positive energy set the tour off to a great start. He clearly laid out the outline of the tour: 1st hour to see sea animals, 2nd hour of snorkeling with a boat slide, 3rd hour boat ride back including lunch and hula dancing. Driver Mahea greeted us warmly and safely drove the large bus from and to Waikiki. Captain Jerry was informative and included our 6-year-old daughter to "drive" the boat and it was a highlight of her Oahu trip. Ben and Kainoa were friendly, made sure we had the appropriate snorkeling gear/life jackets for the kids, and gave beautiful hula dances. Cyre had great energy and was informative on the boat ride. Flo and Faavae were great in guiding the water activities. We saw dolphins, snorkeled with turtles, enjoyed the boat ride, and appreciated how a little bit of the Hawaiian culture was incorporated into the tour. Great vibes allover! Thank you to this crew!
