Great experience!

5.00Great experience. We were a group of 9, 10 to 77. Crew was very good. Friendly, safety conscious and good teachers. The younger 3 10, 11 and 13 had a really good first time experience. Parents were very relaxed and trusting of the staff.
Capt Crash was great.

5.00We had an incredible time on our snorkel trip with Oahu Catamarans—it was easily one of the highlights of our visit to Oahu! From start to finish, the crew made the entire experience fun, safe, and unforgettable. A huge shoutout to Captain Crash, Shannon, Lucy, and Sushi—they were absolutely amazing. Captain Crash kept everything running smoothly while making the ride exciting and enjoyable, and the crew’s energy was contagious. Shannon and Lucy were super attentive and helpful in the water, making sure everyone felt comfortable and confident while snorkeling. Sushi kept everyone laughing and added a great vibe to the whole trip. 🐠🌊 The snorkeling itself was fantastic, with clear water and tons of marine life. Being out on the catamaran with the views of Waikiki and the open ocean was an experience we won’t forget. The crew shared great tips, pointed out sea life, and made sure everyone got the most out of their time in the water. What really stood out was how friendly and personable the entire team was—they treated everyone like family and made the trip feel special rather than just another tour. Their professionalism and enthusiasm made the whole adventure feel safe, relaxed, and incredibly fun. 😄 If you’re visiting Oahu and considering a snorkel trip, we highly recommend booking with Oahu Catamarans and hoping you get this crew—you won’t regret it!
Well Worth It!

5.00Went out as a family. Had a great time. Saw plenty of turtles as promised. Lucy, Shannon, Krash and Sushi were all awesome! Lucy was very knowledgeable about the turtles and explained things while in the water. Light snack and drinks after the snorkel.
Thanks Sushi

2.00This caption. (I guess there.is more than 1) couldnt.not.have been more grouchy and unwelcoming. Barking orders. Even when asked for help w sons mask, he just said, "thats because he has it on wrong, like I said " the kid is nine! I didnt.find the 2 girls.very nice either. The worst parts were all the other boats (I counted 6) were having a grand old time. One.fellow passenger said, "thats the fun boat" re the boat nearest ours. I'd pay more and find a friendly crew.
You get what you pay for

2.00It was rainy which didn't help, but ive never met a grouchier, less fun crew. Capt. Didn't interact with us at all...barked out rules and put out tiny bags of chips. Capt. Never welcomed us, never smiled, just listed all the rules starting w our shoes... His two assistants weren't much friendlier. It just really didn't leave you feeling appreciated at all. Then they asked for tips! Thank God there were other passengers to talk to.

5.00This was a great experience. We saw lots of turtles, fish, and marine life! Krash, Lucy, Margaret, and Sushi made the experience awesome and seamless. If you have never swam in the ocean or snorkeled before, I would gain a bit of experience in that area before booking as you are swimming in water 25-35 ft deep (2-3 meters). Overall a highlight of our trip and we would highly recommend this excursion!

4.00Was a great trip with the crew, water wasn’t ideal for snorkeling as it was still cloudy from the storm, but on a good day it would have been great. Captured 3-4 turtles on my underwater camera, and lots of fish. Was worth the money for sure.
