Thanks to your professional, experienced crew, the Oahu shark dive is completely safe as they know the predators’ behavior, and the underwater cage provides proven safety against all different species of sharks. Whether you’re in the cage with sharks right in front of you or watching from up in the boat, Oahu shark diving is a Hawaii activity you’ll definitely never forget.

Gabrielle_M, May 2026

Memories are priceless

This was an amazing experience! He is an excellent teacher and super motivating. My daughter and husband had an unbelievable time and amazing experience. The memories we made were priceless and the surf lessons were 100% worth it. We will book in the future on our next trip back

Adam_S, May 2026

Expect a lot of people...

Expect a lot of people from other excursions in the water. But once you're in the water, take your time to appreciate what you're doing. There's another world below the surface. Schools of fish everywhere. Turtles were on the bottom of the sea floor and some breached the surface for air before they dove back down. The ride was comfortable and the crew were very knowledgeable and super friendly. A great way to spend 2 hours of your day.

Family, Private & Group Surf Lessons w/ Waikiki Courtesy Shuttle

Cheyenne_L, Apr 2026

Awesome Surf Instructors

The people at Ohana Surf Project were helpful, supportive, and laid back. Maddie in the office was more than willing to answer any questions and help with anything before the trip. Our lesson was with Kevin and he was supportive and encouraging and told us exactly what we needed to do to get up and have the best surfing experience. He was knowledgeable and chose the waves that would give us the best chance. Chelsea was taking photos/videos also gave advice on surfing. We had a semi private lesson which meant that there were two of us in our group with one instructor and about three other groups with their instructors sharing the same space. The instructors would all look out for the group in terms of safety but they focused their lessons only on their students. We had an awesome time, everyone got up on the board who wanted to, and I would definitely recommend them to anyone looking for a surf lesson, especially beginners.

We had so much fun...

We had so much fun snorkeling. Everyone on the crew was super chill and knowledgeable. Haley was our guide in the water. You could tell she was in her element and loved what she did. I would highly recommend booking with this crew. We even got to seem some spinner dolphins.

100/10 experience.

It was fantastic! The crew was very informative and helpful as well as funny, very attentive. We saw quite a few different types of fish, as well as beautiful green turtles. They check before letting everyone off to make sure you see some ocean life :) the slide was great for all ages, the experience was more than I could asked for! I will recommend these guys time and time again! We rented a go pro and they were extremely helpful with getting the pictures uploaded to are phone. One tour guide even helped up get an amazing video of one of the turtles!!!! The boat was very clean and very nice. We saw dolphins and even a whale on the way out :) you won’t be disappointed:)! I do recommend you know how to swim, it doesn’t have to be life guard level but doggy paddle will get you pretty far with the floaters and flippers and all that they provide. They do make sure to address that, and are fine helping you and even encourage you to talk to the in private if it’s something you don’t want the whole boat knowing :) I would rate it 100/10

Captain Bruce Kaneohe Sandbar Experience

Very fun day with the Captain Bruce crew out on the Kaneohe sandbar! Great crew, lovely snorkeling and scenery, and tasty snacks! A great trip for all ages - easy to get on and off the boat, different water sports activities available, or just beautiful scenery out on the water if you didn't feel like doing much. All of us really enjoyed this activity and the day. It was definitely a highlight of our trip to Oahu!

Best Voyage Yet

What can I say? This boat ride was EVERYTHING and more! Kyle, Johnny, and Justin made sure everyone felt welcomed and included throughout the whole time. I beat cancer last year, and for them to go above and beyond to make me feel special was life-changing. Justin driving the boat was phenomenal! Don’t waste anytime just BOOK!

Be prepared to pay a little more when you arrive

These guys were very professional and helpful. We had a great time. Just be aware, you will end up paying another $100 on top of what you paid for this excursion. You'll pay fuel service charge, parking, pictures, and tip. But, it's Hawaii, so I guess it's par for the course with everything in paradise.

Rainbow Helicopters is first rate!

The Rainbow Helicopter team is professional and helpful. They are really responsive to questions through the Viator app. Josh was the pilot for today's flight. He was excellent handling the bird and answering questions. It was my first helicopter ride and I felt confident in his ability to show us around the island and get us safely back on the ground.

Pearl Harbor Remembered Tour

Scott_D, Jun 2025

Excellent tour

This was a great tour and the guide was excellent at both sharing stories on the way to and from Pearl Harbor, but also preparing us to get the most out of our time at the USS Arizona and USS Missouri. Our time was adjusted due to availability of the boat shuttle to the Arizona memorial, but that is common. Communication on the change was excellent: a text, call and email. I would recommend this tour to anyone. We appreciated the pickup in Waikiki near our hotel!
