My wife and I were looking for a low key, no booze cruise excursion to Turtle Canyon. We were SO happy with Mana Kai. We picked up the boat right in Waikiki, were greeted by the first mate who was super nice. Boat was clean, crew and captain great and we had a lifeguard on board which I loved since my wife is not a strong swimmer. It was a very relaxing ride out with a gorgeous view of Diamondhead. We had about an hour in the water and saw three turtles and lots of fish. No amentiies on board, bring your own water, snacks and plan ahead. They had great equipment but you can also bring your own. It was the perfect length. We did the 11:30 am tour and were back for lunch. I only wonder if the visibility is better in the morning since the sun was shining down at noon. I would definitely go with them again and please tip the hardworking crew at the end of the tour.
