Captain Joey and the girls on 10/25/25 were absolutely amazing. The girls were very helpful and kind to everyone. I highly recommend this tour and we will be back in the future for a sunset cruise.

They cancelled the excursion less than 12 hours before start time. Said there was not enough people to make it worth their time. Two days later, I still have not received a refund. And, it should be noted, they avoided any use of the Viator platform when canceling the excursion.

The staff including Captain JoJo, Kelley and Whitney were phenomenal! Very attentive, informative, and professional. Ftom the time i arrived through the end of the excursion was a great experience. We saw many turtles and enjoyed the time in the boat as much as in the water. Highly recommend this turtle excursion! Also, the transportation was on time and prompt both arriving and returning!

This felt like a private cruise. The boat was fantastic, and the crew provided top service. If we are ever back in Honolulu we will definitely do this again.

Snorkelling with the turtles was absolutely unforgettable. We saw several turtles up close – some resting on the ocean floor, others swimming right by us without a care in the world. They were majestic and peaceful. Topper, Sofia & Natalie were knowledgeable and respectful of the sea life, making sure we kept a safe and non intrusive distance. Highly recommend!
