Amazing experience! The...

Amazing experience! The surfing coaches were patient, encouraging, and incredibly helpful. They explained the techniques in a way that was easy to understand, especially as a beginner. The entire experience was fun from start to finish, and I left feeling more confident, excited, and ready to catch the next wave! 🌊🏄‍♀️

Afternoon Snorkeling Tour!

Great tour, lots of sea turtles and fish!! I am so glad we chose this tour as it was a lot smaller compared to other tours out there and was able to be more intimate. We went on the afternoon tour and in our exact tour group there was only 5 of us so it was really nice! Margaret & Riley were great tour guides in the water and were excellent crew! They had good recommendations for food and Riley was very knowledgeable about the sea life!! Would definitely book again with this company & crew!!

1 Hour Waikiki Sail on Na Hoku 3 Catamaran

Heather_G, Jul 2026

Loved it!

Our family had an amazing time! Our daughter absolutely loved sitting up front where she got splashed by the waves—it was the highlight of the trip for her. My husband preferred to stay farther back since he didn’t want to get wet, and he really enjoyed the ride and the beautiful views. It was the perfect experience because everyone could enjoy it their own way. We would definitely recommend this boat trip to families and would happily do it again!

Waikiki and Diamond Head Parasailing Experience

Staci_G, Apr 2026

Blast for 50+ First Time Parasailing

I was reluctant to try parasailing, but I'm so glad I did. I'm in my 50s and had a blast. My 22 year old son was my partner. Sundance and Dawson are fabulous. They had us all laughing and made us all comfortable. Julie that handles reservations and check in was so sweet and friendly. If you're thinking about parasailing, Extreme Parasailing with this crew is the only way to go!

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: USS Arizona Memorial & USS Missouri Battleship Tour from Waikiki

Harry_G, Sep 2025

Wonderful Experience at Pearl Harbor

Awesome 9 hour tour. Will was great. He explained the process that we had to go through to see the USS Arizona Memorial. Everyone on our bus got ample time to see the memorial as well as a tour on the USS Missouri. After seeing both areas he took us to the National Memorial Cemetery of the Pacific which was also so amazing and great views of Honolulu. He showed us and told us other highlights on the island. We really enjoyed the tour. He was prompt picking us up at our designated location.
